<div>== Introduction ==<br />
The best way to prepare for math contests is to '''do lots of practice problems''' and learn the material necessary to solve the problems. There are also many books and online handouts/lectures you can use to improve your problem-solving skills. Depending on your current abilities, you will want to start out with different practice problems, different books, and in different areas of the forums. You should also try to strengthen in the areas you are not as good at. This guide is intended to help you get started.<br />
<br />
== Books ==<br />
AoPS has a list of books available through the website, separated by contest level, [http://www.artofproblemsolving.com/Books/AoPS_B_CP.php here]. <br />
<br />
The '''Art of Problem Solving books''' are an excellent resource to help prepare for math contests. They cover a broad range of topics, from algebra to geometry to number theory to combinatorics and much much more. <br />
<br />
* Art of Problem Solving Volume 1 - [[Mathcounts]], [[AMC 8]], [[AMC 10]]<br />
* Art of Problem Solving Volume 2 - [[AMC 12]], [[AIME]], [[USAMO]], [[MOP]]<br />
<br />
The '''AoPS textbooks''' break down specific areas of mathematics. These books are on 3 levels, Introductory, Intermediate, and Advanced. The Advanced series, as well as part of the Intermediate series, has not yet been published. These books are indexed [https://artofproblemsolving.com/store/recommendations.php#state/240 here]. Excerpts are provided, as well as pretests and posttests to see if the books are on the right level for you. '''Alcumus''' is a good resource even if you do not own any of the AoPS books.<br />

<br />
Here are some old contest archives that may be useful for practicing with:<br />

* [[USAMO Problems and Solutions]] - [http://www.artofproblemsolving.com/Forum/resources.php?c=182&cid=27 USAMO] is a proof-based contest which must be qualified for through a combination of AMC & AIME scores.<br />
<br />

<br />
<br />
<br />
<br />
<br />
There are certain strategies in preparing for the AMC 10/12- especially qualification for the AIME. <br />
<br />
<br />
<br />
The AIME cutoff on the AMC 12 have ranged throughout (84-96) in the recent years. The top 5% of scorers qualify. In order to get a score in the range, a simple way is to answer 13 questions right and leave the rest blank which earns a score of 96. In the past, cutoffs have been around 100.5 but it’s very rare as contests are getting slightly harder year by year. This means, since the first 10 questions should be solved by nearly anyone, they are 60 “free” points. Throughout questions 10-20, answering 3-5 shall be enough.<br />
<br />
<br />
<br />
<br />
Qualification for the USAMO however is much harder. Only 260-270 people qualify every year. USAMO qualifiers need a good combination of AMC & AIME scores. The average score on the AMC 12 for a USAMO qualifier is around 114-132. There are simple ways to do this but it takes a lot of work. Answering the first 15 right, and then getting 5 out of the 10 left would usually qualify.<br />
<br />
<br />
<br />
<br />
The AIME cutoff on the AMC 10 have ranged throughout (102-120) in recent years. The top 2.5% of scorers qualify. The AMC 10 does test less topics than the AMC 12 but many questions go into much more depth. Cutoffs on the AMC 10 are higher since the testing only tests topics up to Geometry. AIME ranges from Algebra to precalculus, which means only very elite scorers make it. Though the qualifying scores are high, there is indeed a good strategy. Since you get 1.5 points for each question blank, it’s good just to do what you know. Answering 15 questions right and leaving the rest blank would earn a score of 105 while answering 20 right and leaving the rest blank would earn a score of 127.5. Since contests are getting harder as said earlier, 15-18 right should be enough. <br />
<br />
<br />
<br />
<br />
Qualifications for the USAJMO is similar to that for the USAMO except they use AMC 10 scores.<br />

Harvard-MIT Mathematics Tournament:<br />
* [https://www.hmmt.co/archive/problems/ HMMT] is a nice contest on a hard AIME level.<br />

<br />
There are certain strategies in preparing for the AMC 10/12- especially qualification for the AIME. <br />
<br />
<br />
<br />
The AIME cutoff on the AMC 12 have ranged throughout (84-96) in the recent years. The top 5% of scorers qualify. In order to get a score in the range, a simple way is to answer 13 questions right and leave the rest blank which earns a score of 96. In the past, cutoffs have been around 100.5 but it’s very rare as contests are getting slightly harder year by year. This means, since the first 10 questions should be solved by nearly anyone, they are 60 “free” points. Throughout questions 10-20, answering 3-5 shall be enough.<br />
<br />
<br />
<br />
<br />
Qualification for the USAMO however is much harder. Only 260-270 people qualify every year. USAMO qualifiers need a good combination of AMC & AIME scores. The average score on the AMC 12 for a USAMO qualifier is around 114-132. There are simple ways to do this but it takes a lot of work. Answering the first 15 right, and then getting 5 out of the 10 left would usually qualify.<br />
<br />
<br />
<br />
<br />
The AIME cutoff on the AMC 10 have ranged throughout (102-120) in recent years. The top 2.5% of scorers qualify. The AMC 10 does test less topics than the AMC 12 but many questions go into much more depth. Cutoffs on the AMC 10 are higher since the testing only tests topics up to Geometry. AIME ranges from Algebra to precalculus, which means only very elite scorers make it. Though the qualifying scores are high, there is indeed a good strategy. Since you get 1.5 points for each question blank, it’s good just to do what you know. Answering 15 questions right and leaving the rest blank would earn a score of 105 while answering 20 right and leaving the rest blank would earn a score of 127.5. Since contests are getting harder as said earlier, 15-18 right should be enough. <br />
<br />
<br />
<br />
<br />
Qualifications for the USAJMO is similar to that for the USAMO except they use AMC 10 scores.<br />

<br />
==Solution 1==<br />
<br />
We compute <math>2^8+1=257</math>. We're all familiar with what <math>6^3</math> is, namely <math>216</math>, which is too small. The smallest cube greater than it is <math>7^3=343</math>. <math>2^{18}+1</math> is too large to calculate, but we notice that <math>2^{18}=(2^6)^3=64^3</math>, which therefore clearly will be the largest cube less than <math>2^{18}+1</math>. So, the required number of cubes is <math>64-7+1= \boxed{\textbf{(E) }58}</math><br />
<br />
==Solution 2 (Brute force)==<br />
First, <math>2^8+1=257</math>. Then, <math>2^{18}+1=262145</math>. Now, we can see how many perfect cubes are between these two parameters. By guessing and checking, we find that it starts from <math>7</math> and ends with <math>64</math>. Now, by counting how many numbers are between these, we find the answer to be <math>\boxed{\textbf{(E) }58}</math><br />

<hr />
<div>==Problem 1==<br />
An amusement park has a collection of scale models, with a ratio <math> 1: 20</math>, of buildings and other sights from around the country. The height of the United States Capitol is 289 feet. What is the height in feet of its duplicate to the nearest whole number?<br />
<br />
<math>\textbf{(A) }14\qquad\textbf{(B) }15\qquad\textbf{(C) }16\qquad\textbf{(D) }18\qquad\textbf{(E) }20</math><br />
<br />
==Solution 1==<br />
<br />
<br />
You can see that since the ratios of real building's heights to the model building's height is 1:20. We also know that the U.S Capitol is 289 feet in real life so to find the height of the model, we divide by 20. That gives us 14.45 which rounds to 14. So the answer is <math>\boxed{\textbf{(A)}14}</math>. That is how I did it ~avamarora.<br />
<br />
==Solution 2==<br />
<br />
<br />
You can just do <math>\frac{289}{20}</math> and round your answer to get <math>\boxed{\textbf{(A)}14}</math>.<br />
It is basically Solution 1 without the ratio calculation, which might not be necessary.<br />
<br />
==Solution 3==<br />
We know that <math> 20 \cdot 14 = 280 ,</math> and that <math> 20 \cdot 15 = 300 .</math> These are the multiples of <math>20</math> around <math>289 ,</math> and the closest one of those is <math>280.</math> Therefore, the answer is <math> \dfrac {280} {14} = \boxed{\textbf{(A) }14} .</math><br />

<br />
This is a community created list of Frequently Asked Questions about Art of Problem Solving. If you have a request to edit or add a question on this page, please make it [http://www.artofproblemsolving.com/Forum/viewtopic.php?f=416&t=414129 here].<br />
<br />
== General==<br />
<br />
<br />
==== Can I change my username? ====<br />
<br />
: It is possible for you to contact AoPS and change your username. However, AoPS typically only changes usernames for privacy reasons (e.g., your current username reveals personal information) or if the username contains inappropriate content. AoPS will not change your username for other reasons (e.g., current username is too "cringy").<br />
<br />
==== What Will Happen to My Account if I change my username? ====<br />
In the extremely rare case that your username does get switched, your contribution history will not be transferred to your new account<br />
: *You will have the same AoPS friends, messages, and post in the my message section<br />
: *Your scores or data for Reaper, Greed Control, and For The Win will be transferred to your new account<br />
: *Your account information will update for AoPS Academy and Beast Academy<br />
<br />
==== Why can't I change my avatar? ====<br />
: You must be a user for two weeks before changing your avatar. You can customize your avatar by downloading a picture and changing the dimensions via computer; however, it's really hard to get a good-looking picture under the size limit. Instead, you could visit one of the many avatar shops to get one (try searching "avatar shop" in other forums on the community page).<br />
<br />
==== Something looks weird (e.g., blurry, missing line, etc.) ====<br />
<br />
:This likely to be because of zoom-in area. Please make sure your zoom level is at 100% or is reset for correct rendering of the web page. If it is at 100% and still doesn't look right, try to refresh or hard refresh. If it still continues looking weird, follow the instructions [https://artofproblemsolving.com/community/c10h1076079_red_me_first__how_to_write_a_bug_report here] to submit a bug report about it in Site Support.<br />
<br />
==== Can I make more than one account?==== <br />
<br />
: Short answer: No.<br />
<br />
: Long answer: Multiple accounts (multis) are banned on AoPS. Having more than one account leads to issues of not remembering on what account you did what. Using multiple accounts in an attempt to "game" the system, (e.g. reaper in some way) or otherwise violate the ToS without consequences will lead to all or some of your accounts being deactivated. If you have already made additional accounts, please choose one account and stop using the others.<br />
<br />
====What software does Art of Problem Solving use to run the website?====<br />
<br />
:* Search: Solr<br />
:* Wiki: MediaWiki<br />
:* Asymptote and <math>\text{\LaTeX}</math> are generated through their respective binary packages<br />
:* Videos: YouTube<br />
:* PyWindow: Skulpt<br />
<br />
:All other parts of the website are custom built.<br />
<br />
== Forums ==<br />
<br />
====How do I create a forum?====<br />
<br />
:To create an AoPS forum, a user must be on the AoPS community for at least 2 weeks. To create a forum, hover over the community tab, then click "My AoPS." You should now see your avatar, along with your profile info, and a list of your friends. Now, click on the "My Forums" tab. There, you would be able to see which forum you moderate or administrate, as well as the private forums you can access. Click on the "+" button at the top right. This should lead you to a forum creating page.<br />
<br />
:Your forum name must be unique and it must be 50 characters or less and your forum description must be 240 characters or less.<br />
<br />
====Why do some posts say they were posted in the future?====<br />
:The AoPS clock is based on the official Naval Observatory time. This is considered the most accurate time. If your computer's system clock is behind the correct time, recent posts may indicate they were posted in the future. Please correct your computer's clock or enable clock synchronization so that your clock is always correct. Mac users may wish to check [http://www.macinstruct.com/node/92 Synchronize your Mac's Clock With A Time Server]. You can also check [http://www.time.gov the US offical time] which will also show you how much your clock is off.<br />
<br />
====Why do some threads have less posts than the number of the latest post?====<br />
:This is because of deleted posts. When posts get deleted, their post number is not reused.<br />
<br />
====I've lost admin access to a forum or blog I created, how do I get it back?====<br />
:Please send an email to sheriff@aops.com with the issue and URL of your forum. They will research your request and restore admin access to your forum if appropriate.<br />
<br />
====What should I do if I find a glitch in the community?====<br />
:First, search the Site Support forum to check if your issue has already been reported.<br />
<br />
:If your issue isn't reported, try refreshing your browser page. Most issues go away after a refresh and there is no need to report the issue unless it continues after you refresh your browser. You can refresh on most browsers in Windows and Chrome OS with Ctrl + R and on Mac with Cmd + R. To Hard Refresh, click Shift between Ctrl/Cmd and R.<br />
<br />
:Some commonly known glitches that should not be reported are avatars appearing twice in the topic list or private message, friends appearing more than once in the friend list, the edit icon showing next to a message when it shouldn't, and not being able to search for a forum after going back a page in the community.<br />
<br />
==== How do I format my post, e.g. bold text, add URLs, etc.? ====<br />
<br />
:AoPS is based on a markup language called BBCode. A tutorial of its functions on AoPS and how to use them can be found [[BBCode:Tutorial|here]].<br />
<br />
==== How do I hide content in the forums? ====<br />
:Wrap the content you want to hide in [hide] tags. This will make a clickable label that, once clicked, will reveal the content.<br />
[hide]Content[/hide]<br />
:If you want to customize the label, or have it says something other than "Click here to reveal hidden text", you can do something like:<br />
[hide=Label to display]Content[/hide]<br />
<br />
:Alternatively, wrap the content you want to hide in [tip] tags. This will make a hoverable label that, once hovered over, will reveal the content.<br />
[tip]Content[/tip]<br />
:If you want to customize the label, instead of saying "Hover for tip", you can do something like:<br />
[tip=Label to display]Content[/tip]<br />
<br />
====I got the message "Too many messages." when trying to send a private message, why?====<br />
:To prevent PM spam abuse like "hvbowibvibviorybvirusbshbiuovvisuvib", users with less than five forum posts are limited to four private messages within a forty-eight hour period.<br />
<br />
==== Posting often makes me a better user, right? ====<br />
<br />
:No. The quality of your posts matter far more than the number of posts you make. In fact, if you make too many unnecessary and spammy posts, you may find your posting privileges revoked.<br />
<br />
==== I have made some posts but my post count did not increase. Why? ====<br />
:Some forums, including the Test Forum, Mafia!, Fun Factory, The Learning Forum, and most user created forums, do not count toward total posts.<br />
<br />
==== I believe a post needs corrective action. What should I do? ====<br />
:If you believe a post needs moderative action, you may report it by clicking the <font face="aops">Z</font> icon on the upper-right corner of that post. If it's a minor mistake, you may want to PM the offending user instead and explain how they can make their post better.<br />
<br />
==== How do I post images? ====<br />
:While AoPS forums have the ability to attach images, we do not generally recommend doing so, as we can not guarantee the images will be available through upgrades, restorations, etc. We also have limited disk space which causes us to remove attachments from time to time. Therefore, we recommend using a third party image hosting solution. There are many options, but we recommend imgur.com.<br />
<br />
:* Go to https://imgur.com<br />
:* Click New Post<br />
:* Upload your image<br />
:* Mouse over image<br />
:* Click the 3 dots in upper right corner<br />
:* Click <b>Get Share Links</b><br />
:* Find the BBCode option and click the green Copy Link button<br />
:* Paste the copied info into your forum or blog post.<br />
<br />
:Or, if you are using an online picture you can right click on it, click inspect, get the image link (usually ends in '.jpg') and paste it into AoPS [img][/img] tags.<br />
<br />
====How do I become a moderator of a forum?====<br />
:The creators of user-created forums select moderators in several different ways. Contact the creator(s) of the forum for more information.<br />
<br />
== Blogs ==<br />
==== How come I can't create a blog? ====<br />
:In order to be able to create a blog on AoPS, you must be a member of the community for at least 2 weeks, before creating any sort of blog, forum, or etc.<br />
<br />
==== How do I make my blog look nice? ====<br />
:Many AoPSers make their blogs look nice by applying CSS, which is a high-level stylesheet language. This can be done by typing code into the CSS box in the Blog Control Panel.<br />
:Try copying CSS of other blogs but give them credit!<br />
<br />
==== Blog Settings ====<br />
:The maximum amount of characters for the Post Comment Text, Comments Text, One Comment Text, and No Comments Text is '''40 characters'''<br />
<br />
== Alcumus ==<br />
<br />
==== How is rating computed? ====<br />
:The rating is more of a prediction of what percentage of problems in the topic the Alcumus engine believes you will get correct. As you get more and more correct, the rating will go up slower and slower. However, if you are predicted to get most correct, and you miss one or two problems, the rating, or prediction of percentage correct, will go down.<br />
<br />
==== I am stuck on a problem, and changing the topic does not change the problem. ====<br />
:Alcumus provides review problems to make sure you still recall information learned from the past. You may not skip these problems.<br />
<br />
== Contests ==<br />
==== Where can I find past contest questions and solutions? ====<br />
:You can find them in the [http://www.artofproblemsolving.com/Forum/resources.php Contests] section.<br />
<br />
==== How do I get problems onto the contest page? ====<br />
<br />
:Make a topic for each question in the appropriate forum, copy/paste the urls to the National Olympiad. Your problems may eventually be submitted into the Contest page.<br />
<br />
==== What are the guidelines for posting problems to be added to the contests section? ====<br />
:Refer to the [http://www.artofproblemsolving.com/Forum/viewtopic.php?f=144&t=195579 guidelines in this post].<br />
<br />
==== Why are the contest collections missing many contest questions ? ====<br />
:Generally, it is because users have not yet posted them onto the wiki (translation difficulties, not having access to the actual problems, lack of interest, etc). If you have a copy, please post the problems in the Community Section! In some cases, however, problems may be missing due to copyright claims from maths organizations.<br />
<br />
====Where are all of the mock contests?====<br />
:User-generated mock contests are now in its separate subforum, [https://artofproblemsolving.com/community/c594864_aops_mock_contests AoPS Mock Contests]. Please use that forum for creating, hosting, participating in, or recruiting writers/test solvers for mock contests.<br />
<br />
====How can I host a mock contest?====<br />
:See posts on [https://artofproblemsolving.com/community/c594864h1168324_hi__im_interested_in_writing_a_mock_contest writing a mock contest] and [https://artofproblemsolving.com/community/c594864h1349281_tips_for_organizing_a_mock_contest Tips for Organizing a Mock Contest].<br />

<br />
Please see the [//artofproblemsolving.com/ftw/faq For the Win! FAQ] for many common questions.<br />
<br />
== School ==<br />
<br />
==== What if I miss a class? ====<br />
:There are classroom transcripts available under My Classes, available at the top right of the web site. You can view these transcripts in order to review any missed material. You can also ask questions on the class message board. Don't worry, though, classroom participation usually isn't weighted heavily.<br />
<br />
==== Is there audio or video in class? ====<br />
:For classes that runs online normally, there is generally no audio or video in the class. The classes are generally text and image based, in an interactive chat room environment, which allows students to ask questions at any time during the class. However, for classes that usually run in the academy, because of the current pandemic, the classes needs to be ran online. To simulate the academy environment, classes will be run on Zoom instead of the AoPS Schoolhouse. As a result, audio will be required and video is recommended.<br />
<br />
==== What if I want to drop out of a class? ====<br />
:For any course with more than 2 classes, students can drop the course any time before the third class begins and receive a full refund. No drops are allowed after the third class has started. To drop the class, go to the My Classes section by clicking the My Classes link at the top-right of the website. Then find the area on the right side of the page that lets you drop the class. A refund will be processed within 10 business days.<br />
<br />
==== For my homework, there is supposed to be a green bar but it's orange, why? ====<br />
<br />
:The bar turns green if and only if the required writing problem(s) is/are attempted.<br />
<br />
==== I need more time for my homework, what should I do? ====<br />
<br />
:There is a "Request Extension" button in the homework tab of your class. This will automatically extend the due date to 2 days after the normal deadline. If you want more time you need to ask for it in the little comment box, stating the reason why you want the extension, and how much time you want. This request will be looked at by the teachers and they will decide if you get the extension or not. Note that you can only use this button 3 times. After, you will need administrator approval.<br />
:Otherwise, you can send an email to extensions@aops.com with your username, class name and ID (the number in the class page URL after https://artofproblemsolving.com/class/) and reason for extension. Someone should get back to you within a couple days.<br />
<br />
==== Why is my post in the AoPS schoolhouse too long? ====<br />
<br />
:The minimum number number of characters allowed in an individual post in the AoPS Schoolhouse is 8 characters. The maximum number of characters allowed in an individual post in the AoPS Schoolhouse is 512 characters.</div>Yelly314https://artofproblemsolving.com/wiki/index.php?title=AoPS_Wiki:FAQ&diff=134055AoPS Wiki:FAQ2020-09-25T18:13:25Z<p>Yelly314: /* I have a question about LaTeX or asymptote, and it's not answered in the wiki.

This is a community created list of Frequently Asked Questions about Art of Problem Solving. If you have a request to edit or add a question on this page, please make it [http://www.artofproblemsolving.com/Forum/viewtopic.php?f=416&t=414129 here].<br />
<br />
== General==<br />
<br />
<br />
==== Can I change my username? ====<br />
<br />
: It is possible for you to contact AoPS and change your username. However, AoPS typically only changes usernames for privacy reasons (e.g., your current username reveals personal information) or if the username contains inappropriate content. AoPS will not change your username for other reasons (e.g., current username is too "cringy").<br />
<br />
==== What Will Happen to My Account if I change my username? ====<br />
In the extremely rare case that your username does get switched, your contribution history will not be transferred to your new account<br />
: *You will have the same AoPS friends, messages, and post in the my message section<br />
: *Your scores or data for Reaper, Greed Control, and For The Win will be transferred to your new account<br />
: *Your account information will update for AoPS Academy and Beast Academy<br />
<br />
==== Why can't I change my avatar? ====<br />
: You must be a user for two weeks before changing your avatar. You can customize your avatar by downloading a picture and changing the dimensions via computer; however, it's really hard to get a good-looking picture under the size limit. Instead, you could visit one of the many avatar shops to get one (try searching "avatar shop" in other forums on the community page).<br />
<br />
==== Something looks weird (e.g., blurry, missing line, etc.) ====<br />
<br />
:This likely to be because of zoom-in area. Please make sure your zoom level is at 100% or is reset for correct rendering of the web page. If it is at 100% and still doesn't look right, try to refresh or hard refresh. If it still continues looking weird, follow the instructions [https://artofproblemsolving.com/community/c10h1076079_red_me_first__how_to_write_a_bug_report here] to submit a bug report about it in Site Support.<br />
<br />
==== Can I make more than one account?==== <br />
<br />
: Short answer: No.<br />
<br />
: Long answer: Multiple accounts (multis) are banned on AoPS. Having more than one account leads to issues of not remembering on what account you did what. Using multiple accounts in an attempt to "game" the system, (e.g. reaper in some way) or otherwise violate the ToS without consequences will lead to all or some of your accounts being deactivated. If you have already made additional accounts, please choose one account and stop using the others.<br />
<br />
====What software does Art of Problem Solving use to run the website?====<br />
<br />
:* Search: Solr<br />
:* Wiki: MediaWiki<br />
:* Asymptote and <math>\text{\LaTeX}</math> are generated through their respective binary packages<br />
:* Videos: YouTube<br />
:* PyWindow: Skulpt<br />
<br />
:All other parts of the website are custom built.<br />
<br />
== Forums ==<br />
<br />
====How do I create a forum?====<br />
<br />
:To create an AoPS forum, a user must be on the AoPS community for at least 2 weeks. To create a forum, hover over the community tab, then click "My AoPS." You should now see your avatar, along with your profile info, and a list of your friends. Now, click on the "My Forums" tab. There, you would be able to see which forum you moderate or administrate, as well as the private forums you can access. Click on the "+" button at the top right. This should lead you to a forum creating page.<br />
<br />
:Your forum name must be unique and it must be 50 characters or less and your forum description must be 240 characters or less.<br />
<br />
====Why do some posts say they were posted in the future?====<br />
:The AoPS clock is based on the official Naval Observatory time. This is considered the most accurate time. If your computer's system clock is behind the correct time, recent posts may indicate they were posted in the future. Please correct your computer's clock or enable clock synchronization so that your clock is always correct. Mac users may wish to check [http://www.macinstruct.com/node/92 Synchronize your Mac's Clock With A Time Server]. You can also check [http://www.time.gov the US offical time] which will also show you how much your clock is off.<br />
<br />
====Why do some threads have less posts than the number of the latest post?====<br />
:This is because of deleted posts. When posts get deleted, their post number is not reused.<br />
<br />
====I've lost admin access to a forum or blog I created, how do I get it back?====<br />
:Please send an email to sheriff@aops.com with the issue and URL of your forum. They will research your request and restore admin access to your forum if appropriate.<br />
<br />
====What should I do if I find a glitch in the community?====<br />
:First, search the Site Support forum to check if your issue has already been reported.<br />
<br />
:If your issue isn't reported, try refreshing your browser page. Most issues go away after a refresh and there is no need to report the issue unless it continues after you refresh your browser. You can refresh on most browsers in Windows and Chrome OS with Ctrl + R and on Mac with Cmd + R. To Hard Refresh, click Shift between Ctrl/Cmd and R.<br />
<br />
:Some commonly known glitches that should not be reported are avatars appearing twice in the topic list or private message, friends appearing more than once in the friend list, the edit icon showing next to a message when it shouldn't, and not being able to search for a forum after going back a page in the community.<br />
<br />
==== How do I format my post, e.g. bold text, add URLs, etc.? ====<br />
<br />
:AoPS is based on a markup language called BBCode. A tutorial of its functions on AoPS and how to use them can be found [[BBCode:Tutorial|here]].<br />
<br />
==== How do I hide content in the forums? ====<br />
:Wrap the content you want to hide in [hide] tags. This will make a clickable label that, once clicked, will reveal the content.<br />
[hide]Content[/hide]<br />
:If you want to customize the label, or have it says something other than "Click here to reveal hidden text", you can do something like:<br />
[hide=Label to display]Content[/hide]<br />
<br />
:Alternatively, wrap the content you want to hide in [tip] tags. This will make a hoverable label that, once hovered over, will reveal the content.<br />
[tip]Content[/tip]<br />
:If you want to customize the label, instead of saying "Hover for tip", you can do something like:<br />
[tip=Label to display]Content[/tip]<br />
<br />
====I got the message "Too many messages." when trying to send a private message, why?====<br />
:To prevent PM spam abuse like "hvbowibvibviorybvirusbshbiuovvisuvib", users with less than five forum posts are limited to four private messages within a forty-eight hour period.<br />
<br />
==== Posting often makes me a better user, right? ====<br />
<br />
:No. The quality of your posts matter far more than the number of posts you make. In fact, if you make too many unnecessary and spammy posts, you may find your posting privileges revoked.<br />
<br />
==== I have made some posts but my post count did not increase. Why? ====<br />
:Some forums, including the Test Forum, Mafia!, Fun Factory, The Learning Forum, and most user created forums, do not count toward total posts.<br />
<br />
==== I believe a post needs corrective action. What should I do? ====<br />
:If you believe a post needs moderative action, you may report it by clicking the <font face="aops">Z</font> icon on the upper-right corner of that post. If it's a minor mistake, you may want to PM the offending user instead and explain how they can make their post better.<br />
<br />
==== How do I post images? ====<br />
:While AoPS forums have the ability to attach images, we do not generally recommend doing so, as we can not guarantee the images will be available through upgrades, restorations, etc. We also have limited disk space which causes us to remove attachments from time to time. Therefore, we recommend using a third party image hosting solution. There are many options, but we recommend imgur.com.<br />
<br />
:* Go to https://imgur.com<br />
:* Click New Post<br />
:* Upload your image<br />
:* Mouse over image<br />
:* Click the 3 dots in upper right corner<br />
:* Click <b>Get Share Links</b><br />
:* Find the BBCode option and click the green Copy Link button<br />
:* Paste the copied info into your forum or blog post.<br />
<br />
:Or, if you are using an online picture you can right click on it, click inspect, get the image link (usually ends in '.jpg') and paste it into AoPS [img][/img] tags.<br />
<br />
====How do I become a moderator of a forum?====<br />
:The creators of user-created forums select moderators in several different ways. Contact the creator(s) of the forum for more information.<br />
<br />
== Blogs ==<br />
==== How come I can't create a blog? ====<br />
:In order to be able to create a blog on AoPS, you must be a member of the community for at least 2 weeks, before creating any sort of blog, forum, or etc.<br />
<br />
==== How do I make my blog look nice? ====<br />
:Many AoPSers make their blogs look nice by applying CSS, which is a high-level stylesheet language. This can be done by typing code into the CSS box in the Blog Control Panel.<br />
:Try copying CSS of other blogs but give them credit!<br />
<br />
==== Blog Settings ====<br />
:The maximum amount of characters for the Post Comment Text, Comments Text, One Comment Text, and No Comments Text is '''40 characters'''<br />
<br />
== Alcumus ==<br />
<br />
==== How is rating computed? ====<br />
:The rating is more of a prediction of what percentage of problems in the topic the Alcumus engine believes you will get correct. As you get more and more correct, the rating will go up slower and slower. However, if you are predicted to get most correct, and you miss one or two problems, the rating, or prediction of percentage correct, will go down.<br />
<br />
==== I am stuck on a problem, and changing the topic does not change the problem. ====<br />
:Alcumus provides review problems to make sure you still recall information learned from the past. You may not skip these problems.<br />
<br />
== Contests ==<br />
==== Where can I find past contest questions and solutions? ====<br />
:You can find them in the [http://www.artofproblemsolving.com/Forum/resources.php Contests] section.<br />
<br />
==== How do I get problems onto the contest page? ====<br />
<br />
:Make a topic for each question in the appropriate forum, copy/paste the urls to the National Olympiad. Your problems may eventually be submitted into the Contest page.<br />
<br />
==== What are the guidelines for posting problems to be added to the contests section? ====<br />
:Refer to the [http://www.artofproblemsolving.com/Forum/viewtopic.php?f=144&t=195579 guidelines in this post].<br />
<br />
==== Why are the contest collections missing many contest questions ? ====<br />
:Generally, it is because users have not yet posted them onto the wiki (translation difficulties, not having access to the actual problems, lack of interest, etc). If you have a copy, please post the problems in the Community Section! In some cases, however, problems may be missing due to copyright claims from maths organizations.<br />
<br />
====Where are all of the mock contests?====<br />
:User-generated mock contests are now in its separate subforum, [https://artofproblemsolving.com/community/c594864_aops_mock_contests AoPS Mock Contests]. Please use that forum for creating, hosting, participating in, or recruiting writers/test solvers for mock contests.<br />
<br />

Please see the [//artofproblemsolving.com/ftw/faq For the Win! FAQ] for many common questions.<br />
<br />
== School ==<br />
<br />
==== What if I miss a class? ====<br />
:There are classroom transcripts available under My Classes, available at the top right of the web site. You can view these transcripts in order to review any missed material. You can also ask questions on the class message board. Don't worry, though, classroom participation usually isn't weighted heavily.<br />
<br />
==== Is there audio or video in class? ====<br />
:For classes that runs online normally, there is generally no audio or video in the class. The classes are generally text and image based, in an interactive chat room environment, which allows students to ask questions at any time during the class. However, for classes that usually run in the academy, because of the current pandemic, the classes needs to be ran online. To simulate the academy environment, classes will be run on Zoom instead of the AoPS Schoolhouse. As a result, audio will be required and video is recommended.<br />
<br />
==== What if I want to drop out of a class? ====<br />
:For any course with more than 2 classes, students can drop the course any time before the third class begins and receive a full refund. No drops are allowed after the third class has started. To drop the class, go to the My Classes section by clicking the My Classes link at the top-right of the website. Then find the area on the right side of the page that lets you drop the class. A refund will be processed within 10 business days.<br />
<br />
==== For my homework, there is supposed to be a green bar but it's orange, why? ====<br />
<br />
:The bar turns green if and only if the required writing problem(s) is/are attempted.<br />
<br />
==== I need more time for my homework, what should I do? ====<br />
<br />
:There is a "Request Extension" button in the homework tab of your class. This will automatically extend the due date to 2 days after the normal deadline. If you want more time you need to ask for it in the little comment box, stating the reason why you want the extension, and how much time you want. This request will be looked at by the teachers and they will decide if you get the extension or not. Note that you can only use this button 3 times. After, you will need administrator approval.<br />
:Otherwise, you can send an email to extensions@aops.com with your username, class name and ID (the number in the class page URL after https://artofproblemsolving.com/class/) and reason for extension. Someone should get back to you within a couple days.<br />
<br />
==== Why is my post in the AoPS schoolhouse too long? ====<br />
<br />
:The minimum number number of characters allowed in an individual post in the AoPS Schoolhouse is 8 characters. The maximum number of characters allowed in an individual post in the AoPS Schoolhouse is 512 characters.</div>Yelly314https://artofproblemsolving.com/wiki/index.php?title=AoPS_Wiki:FAQ&diff=134054AoPS Wiki:FAQ2020-09-25T18:11:19Z<p>Yelly314: /* LaTeX and Asymptote */</p>

==== How do I format my post, e.g. bold text, add URLs, etc.? ====<br />
<br />
:AoPS is based on a markup language called BBCode. A tutorial of its functions on AoPS and how to use them can be found [[BBCode:Tutorial|here]].<br />
<br />
==== How do I hide content in the forums? ====<br />
:Wrap the content you want to hide in [hide] tags. This will make a clickable label that, once clicked, will reveal the content.<br />
[hide]Content[/hide]<br />
:If you want to customize the label, or have it says something other than "Click here to reveal hidden text", you can do something like:<br />
[hide=Label to display]Content[/hide]<br />
<br />
:Alternatively, wrap the content you want to hide in [tip] tags. This will make a hoverable label that, once hovered over, will reveal the content.<br />
[tip]Content[/tip]<br />
:If you want to customize the label, instead of saying "Hover for tip", you can do something like:<br />
[tip=Label to display]Content[/tip]<br />
<br />
====I got the message "Too many messages." when trying to send a private message, why?====<br />
:To prevent PM spam abuse like "hvbowibvibviorybvirusbshbiuovvisuvib", users with less than five forum posts are limited to four private messages within a forty-eight hour period.<br />
<br />
==== Posting often makes me a better user, right? ====<br />
<br />
:No. The quality of your posts matter far more than the number of posts you make. In fact, if you make too many unnecessary and spammy posts, you may find your posting privileges revoked.<br />
<br />
==== I have made some posts but my post count did not increase. Why? ====<br />
:Some forums, including the Test Forum, Mafia!, Fun Factory, The Learning Forum, and most user created forums, do not count toward total posts.<br />
<br />
==== I believe a post needs corrective action. What should I do? ====<br />
:If you believe a post needs moderative action, you may report it by clicking the <font face="aops">Z</font> icon on the upper-right corner of that post. If it's a minor mistake, you may want to PM the offending user instead and explain how they can make their post better.<br />
<br />
==== How do I post images? ====<br />
:While AoPS forums have the ability to attach images, we do not generally recommend doing so, as we can not guarantee the images will be available through upgrades, restorations, etc. We also have limited disk space which causes us to remove attachments from time to time. Therefore, we recommend using a third party image hosting solution. There are many options, but we recommend imgur.com.<br />
<br />
:* Go to https://imgur.com<br />
:* Click New Post<br />
:* Upload your image<br />
:* Mouse over image<br />
:* Click the 3 dots in upper right corner<br />
:* Click <b>Get Share Links</b><br />
:* Find the BBCode option and click the green Copy Link button<br />
:* Paste the copied info into your forum or blog post.<br />
<br />
:Or, if you are using an online picture you can right click on it, click inspect, get the image link (usually ends in '.jpg') and paste it into AoPS [img][/img] tags.<br />
<br />
====How do I become a moderator of a forum?====<br />
:The creators of user-created forums select moderators in several different ways. Contact the creator(s) of the forum for more information.<br />
<br />
== Blogs ==<br />
==== How come I can't create a blog? ====<br />
:In order to be able to create a blog on AoPS, you must be a member of the community for at least 2 weeks, before creating any sort of blog, forum, or etc.<br />
<br />
==== How do I make my blog look nice? ====<br />
:Many AoPSers make their blogs look nice by applying CSS, which is a high-level stylesheet language. This can be done by typing code into the CSS box in the Blog Control Panel.<br />
:Try copying CSS of other blogs but give them credit!<br />
<br />
==== Blog Settings ====<br />
:The maximum amount of characters for the Post Comment Text, Comments Text, One Comment Text, and No Comments Text is '''40 characters'''<br />
<br />
== Alcumus ==<br />
<br />
==== How is rating computed? ====<br />
:The rating is more of a prediction of what percentage of problems in the topic the Alcumus engine believes you will get correct. As you get more and more correct, the rating will go up slower and slower. However, if you are predicted to get most correct, and you miss one or two problems, the rating, or prediction of percentage correct, will go down.<br />
<br />
==== I am stuck on a problem, and changing the topic does not change the problem. ====<br />
:Alcumus provides review problems to make sure you still recall information learned from the past. You may not skip these problems.<br />

Please see the [//artofproblemsolving.com/ftw/faq For the Win! FAQ] for many common questions.<br />
<br />
== School ==<br />
<br />
==== What if I miss a class? ====<br />
:There are classroom transcripts available under My Classes, available at the top right of the web site. You can view these transcripts in order to review any missed material. You can also ask questions on the class message board. Don't worry, though, classroom participation usually isn't weighted heavily.<br />
<br />
==== Is there audio or video in class? ====<br />
:For classes that runs online normally, there is generally no audio or video in the class. The classes are generally text and image based, in an interactive chat room environment, which allows students to ask questions at any time during the class. However, for classes that usually run in the academy, because of the current pandemic, the classes needs to be ran online. To simulate the academy environment, classes will be run on Zoom instead of the AoPS Schoolhouse. As a result, audio will be required and video is recommended.<br />
<br />
==== What if I want to drop out of a class? ====<br />
:For any course with more than 2 classes, students can drop the course any time before the third class begins and receive a full refund. No drops are allowed after the third class has started. To drop the class, go to the My Classes section by clicking the My Classes link at the top-right of the website. Then find the area on the right side of the page that lets you drop the class. A refund will be processed within 10 business days.<br />
<br />
==== For my homework, there is supposed to be a green bar but it's orange, why? ====<br />
<br />
:The bar turns green if and only if the required writing problem(s) is/are attempted.<br />
<br />
==== I need more time for my homework, what should I do? ====<br />
<br />
:There is a "Request Extension" button in the homework tab of your class. This will automatically extend the due date to 2 days after the normal deadline. If you want more time you need to ask for it in the little comment box, stating the reason why you want the extension, and how much time you want. This request will be looked at by the teachers and they will decide if you get the extension or not. Note that you can only use this button 3 times. After, you will need administrator approval.<br />
:Otherwise, you can send an email to extensions@aops.com with your username, class name and ID (the number in the class page URL after https://artofproblemsolving.com/class/) and reason for extension. Someone should get back to you within a couple days.<br />
<br />
==== Why is my post in the AoPS schoolhouse too long? ====<br />
<br />
:The minimum number number of characters allowed in an individual post in the AoPS Schoolhouse is 8 characters. The maximum number of characters allowed in an individual post in the AoPS Schoolhouse is 512 characters.</div>Yelly314https://artofproblemsolving.com/wiki/index.php?title=AoPS_Wiki:FAQ&diff=134053AoPS Wiki:FAQ2020-09-25T18:07:26Z<p>Yelly314: /* How do I post images? */</p>

<br />
This is a community created list of Frequently Asked Questions about Art of Problem Solving. If you have a request to edit or add a question on this page, please make it [http://www.artofproblemsolving.com/Forum/viewtopic.php?f=416&t=414129 here].<br />
<br />
== General==<br />
<br />
<br />
==== Can I change my username? ====<br />
<br />
: It is possible for you to contact AoPS and change your username. However, AoPS typically only changes usernames for privacy reasons (e.g., your current username reveals personal information) or if the username contains inappropriate content. AoPS will not change your username for other reasons (e.g., current username is too "cringy").<br />
<br />
==== What Will Happen to My Account if I change my username? ====<br />
In the extremely rare case that your username does get switched, your contribution history will not be transferred to your new account<br />
: *You will have the same AoPS friends, messages, and post in the my message section<br />
: *Your scores or data for Reaper, Greed Control, and For The Win will be transferred to your new account<br />
: *Your account information will update for AoPS Academy and Beast Academy<br />
<br />
==== Why can't I change my avatar? ====<br />
: You must be a user for two weeks before changing your avatar. You can customize your avatar by downloading a picture and changing the dimensions via computer; however, it's really hard to get a good-looking picture under the size limit. Instead, you could visit one of the many avatar shops to get one (try searching "avatar shop" in other forums on the community page).<br />
<br />
==== Something looks weird (e.g., blurry, missing line, etc.) ====<br />
<br />
:This likely to be because of zoom-in area. Please make sure your zoom level is at 100% or is reset for correct rendering of the web page. If it is at 100% and still doesn't look right, try to refresh or hard refresh. If it still continues looking weird, follow the instructions [https://artofproblemsolving.com/community/c10h1076079_red_me_first__how_to_write_a_bug_report here] to submit a bug report about it in Site Support.<br />
<br />
==== Can I make more than one account?==== <br />
<br />
: Short answer: No.<br />
<br />
: Long answer: Multiple accounts (multis) are banned on AoPS. Having more than one account leads to issues of not remembering on what account you did what. Using multiple accounts in an attempt to "game" the system, (e.g. reaper in some way) or otherwise violate the ToS without consequences will lead to all or some of your accounts being deactivated. If you have already made additional accounts, please choose one account and stop using the others.<br />
<br />
====What software does Art of Problem Solving use to run the website?====<br />
<br />
:* Search: Solr<br />
:* Wiki: MediaWiki<br />
:* Asymptote and <math>\text{\LaTeX}</math> are generated through their respective binary packages<br />
:* Videos: YouTube<br />
:* PyWindow: Skulpt<br />
<br />
:All other parts of the website are custom built.<br />
<br />
== Forums ==<br />
<br />
====How do I create a forum?====<br />
<br />
:To create an AoPS forum, a user must be on the AoPS community for at least 2 weeks. To create a forum, hover over the community tab, then click "My AoPS." You should now see your avatar, along with your profile info, and a list of your friends. Now, click on the "My Forums" tab. There, you would be able to see which forum you moderate or administrate, as well as the private forums you can access. Click on the "+" button at the top right. This should lead you to a forum creating page.<br />
<br />
:Your forum name must be unique and it must be 50 characters or less and your forum description must be 240 characters or less.<br />
<br />
====Why do some posts say they were posted in the future?====<br />
:The AoPS clock is based on the official Naval Observatory time. This is considered the most accurate time. If your computer's system clock is behind the correct time, recent posts may indicate they were posted in the future. Please correct your computer's clock or enable clock synchronization so that your clock is always correct. Mac users may wish to check [http://www.macinstruct.com/node/92 Synchronize your Mac's Clock With A Time Server]. You can also check [http://www.time.gov the US offical time] which will also show you how much your clock is off.<br />
<br />
====Why do some threads have less posts than the number of the latest post?====<br />
:This is because of deleted posts. When posts get deleted, their post number is not reused.<br />
<br />
====I've lost admin access to a forum or blog I created, how do I get it back?====<br />
:Please send an email to sheriff@aops.com with the issue and URL of your forum. They will research your request and restore admin access to your forum if appropriate.<br />
<br />
====What should I do if I find a glitch in the community?====<br />
:First, search the Site Support forum to check if your issue has already been reported.<br />
<br />
:If your issue isn't reported, try refreshing your browser page. Most issues go away after a refresh and there is no need to report the issue unless it continues after you refresh your browser. You can refresh on most browsers in Windows and Chrome OS with Ctrl + R and on Mac with Cmd + R. To Hard Refresh, click Shift between Ctrl/Cmd and R.<br />
<br />
:Some commonly known glitches that should not be reported are avatars appearing twice in the topic list or private message, friends appearing more than once in the friend list, the edit icon showing next to a message when it shouldn't, and not being able to search for a forum after going back a page in the community.<br />
<br />
==== How do I format my post, e.g. bold text, add URLs, etc.? ====<br />
<br />
:AoPS is based on a markup language called BBCode. A tutorial of its functions on AoPS and how to use them can be found [[BBCode:Tutorial|here]].<br />
<br />
==== How do I hide content in the forums? ====<br />
:Wrap the content you want to hide in [hide] tags. This will make a clickable label that, once clicked, will reveal the content.<br />
[hide]Content[/hide]<br />
:If you want to customize the label, or have it says something other than "Click here to reveal hidden text", you can do something like:<br />
[hide=Label to display]Content[/hide]<br />
<br />
:Alternatively, wrap the content you want to hide in [tip] tags. This will make a hoverable label that, once hovered over, will reveal the content.<br />
[tip]Content[/tip]<br />
:If you want to customize the label, instead of saying "Hover for tip", you can do something like:<br />
[tip=Label to display]Content[/tip]<br />
<br />
====I got the message "Too many messages." when trying to send a private message, why?====<br />
:To prevent PM spam abuse like "hvbowibvibviorybvirusbshbiuovvisuvib", users with less than five forum posts are limited to four private messages within a forty-eight hour period.<br />
<br />
==== Posting often makes me a better user, right? ====<br />

:If you believe a post needs moderative action, you may report it by clicking the <font face="aops">Z</font> icon on the upper-right corner of that post. If it's a minor mistake, you may want to PM the offending user instead and explain how they can make their post better.<br />
<br />
==== How do I post images? ====<br />
:While AoPS forums have the ability to attach images, we do not generally recommend doing so, as we can not guarantee the images will be available through upgrades, restorations, etc. We also have limited disk space which causes us to remove attachments from time to time.

<br />
Please see the [//artofproblemsolving.com/ftw/faq For the Win! FAQ] for many common questions.<br />
<br />
== School ==<br />
<br />
==== What if I miss a class? ====<br />
:There are classroom transcripts available under My Classes, available at the top right of the web site. You can view these transcripts in order to review any missed material. You can also ask questions on the class message board. Don't worry, though, classroom participation usually isn't weighted heavily.<br />
<br />
==== Is there audio or video in class? ====<br />
:For classes that runs online normally, there is generally no audio or video in the class. The classes are generally text and image based, in an interactive chat room environment, which allows students to ask questions at any time during the class. However, for classes that usually run in the academy, because of the current pandemic, the classes needs to be ran online. To simulate the academy environment, classes will be run on Zoom instead of the AoPS Schoolhouse. As a result, audio will be required and video is recommended.<br />
<br />
==== What if I want to drop out of a class? ====<br />
:For any course with more than 2 classes, students can drop the course any time before the third class begins and receive a full refund. No drops are allowed after the third class has started. To drop the class, go to the My Classes section by clicking the My Classes link at the top-right of the website. Then find the area on the right side of the page that lets you drop the class. A refund will be processed within 10 business days.<br />
<br />
==== For my homework, there is supposed to be a green bar but it's orange, why? ====<br />
<br />
:The bar turns green if and only if the required writing problem(s) is/are attempted.<br />
<br />
==== I need more time for my homework, what should I do? ====<br />
<br />
:There is a "Request Extension" button in the homework tab of your class. This will automatically extend the due date to 2 days after the normal deadline. If you want more time you need to ask for it in the little comment box, stating the reason why you want the extension, and how much time you want. This request will be looked at by the teachers and they will decide if you get the extension or not. Note that you can only use this button 3 times. After, you will need administrator approval.<br />
:Otherwise, you can send an email to extensions@aops.com with your username, class name and ID (the number in the class page URL after https://artofproblemsolving.com/class/) and reason for extension. Someone should get back to you within a couple days.<br />
<br />
==== Why is my post in the AoPS schoolhouse too long? ====<br />
<br />
:The minimum number number of characters allowed in an individual post in the AoPS Schoolhouse is 8 characters. The maximum number of characters allowed in an individual post in the AoPS Schoolhouse is 512 characters.</div>Yelly314https://artofproblemsolving.com/wiki/index.php?title=AoPS_Wiki:FAQ&diff=134052AoPS Wiki:FAQ2020-09-25T18:07:06Z<p>Yelly314: /* Posting often makes me a better user, right? */</p>

<br />
This is a community created list of Frequently Asked Questions about Art of Problem Solving. If you have a request to edit or add a question on this page, please make it [http://www.artofproblemsolving.com/Forum/viewtopic.php?f=416&t=414129 here].<br />
<br />
== General==<br />
<br />
<br />
==== Can I change my username? ====<br />
<br />
: It is possible for you to contact AoPS and change your username. However, AoPS typically only changes usernames for privacy reasons (e.g., your current username reveals personal information) or if the username contains inappropriate content. AoPS will not change your username for other reasons (e.g., current username is too "cringy").<br />
<br />
==== What Will Happen to My Account if I change my username? ====<br />
In the extremely rare case that your username does get switched, your contribution history will not be transferred to your new account<br />
: *You will have the same AoPS friends, messages, and post in the my message section<br />
: *Your scores or data for Reaper, Greed Control, and For The Win will be transferred to your new account<br />
: *Your account information will update for AoPS Academy and Beast Academy<br />
<br />
==== Why can't I change my avatar? ====<br />
: You must be a user for two weeks before changing your avatar. You can customize your avatar by downloading a picture and changing the dimensions via computer; however, it's really hard to get a good-looking picture under the size limit. Instead, you could visit one of the many avatar shops to get one (try searching "avatar shop" in other forums on the community page).<br />
<br />
==== Something looks weird (e.g., blurry, missing line, etc.) ====<br />
<br />
:This likely to be because of zoom-in area. Please make sure your zoom level is at 100% or is reset for correct rendering of the web page. If it is at 100% and still doesn't look right, try to refresh or hard refresh. If it still continues looking weird, follow the instructions [https://artofproblemsolving.com/community/c10h1076079_red_me_first__how_to_write_a_bug_report here] to submit a bug report about it in Site Support.<br />
<br />
==== Can I make more than one account?==== <br />
<br />
: Short answer: No.<br />
<br />
: Long answer: Multiple accounts (multis) are banned on AoPS. Having more than one account leads to issues of not remembering on what account you did what. Using multiple accounts in an attempt to "game" the system, (e.g. reaper in some way) or otherwise violate the ToS without consequences will lead to all or some of your accounts being deactivated. If you have already made additional accounts, please choose one account and stop using the others.<br />
<br />
====What software does Art of Problem Solving use to run the website?====<br />
<br />
:* Search: Solr<br />
:* Wiki: MediaWiki<br />
:* Asymptote and <math>\text{\LaTeX}</math> are generated through their respective binary packages<br />
:* Videos: YouTube<br />
:* PyWindow: Skulpt<br />
<br />
:All other parts of the website are custom built.<br />
<br />
== Forums ==<br />
<br />
====How do I create a forum?====<br />
<br />
:To create an AoPS forum, a user must be on the AoPS community for at least 2 weeks. To create a forum, hover over the community tab, then click "My AoPS." You should now see your avatar, along with your profile info, and a list of your friends. Now, click on the "My Forums" tab. There, you would be able to see which forum you moderate or administrate, as well as the private forums you can access. Click on the "+" button at the top right. This should lead you to a forum creating page.<br />
<br />
:Your forum name must be unique and it must be 50 characters or less and your forum description must be 240 characters or less.<br />
<br />
====Why do some posts say they were posted in the future?====<br />
:The AoPS clock is based on the official Naval Observatory time. This is considered the most accurate time. If your computer's system clock is behind the correct time, recent posts may indicate they were posted in the future. Please correct your computer's clock or enable clock synchronization so that your clock is always correct. Mac users may wish to check [http://www.macinstruct.com/node/92 Synchronize your Mac's Clock With A Time Server]. You can also check [http://www.time.gov the US offical time] which will also show you how much your clock is off.<br />
<br />
====Why do some threads have less posts than the number of the latest post?====<br />
:This is because of deleted posts. When posts get deleted, their post number is not reused.<br />
<br />
====I've lost admin access to a forum or blog I created, how do I get it back?====<br />
:Please send an email to sheriff@aops.com with the issue and URL of your forum. They will research your request and restore admin access to your forum if appropriate.<br />
<br />
====What should I do if I find a glitch in the community?====<br />
:First, search the Site Support forum to check if your issue has already been reported.<br />
<br />
:If your issue isn't reported, try refreshing your browser page. Most issues go away after a refresh and there is no need to report the issue unless it continues after you refresh your browser. You can refresh on most browsers in Windows and Chrome OS with Ctrl + R and on Mac with Cmd + R. To Hard Refresh, click Shift between Ctrl/Cmd and R.<br />
<br />
:Some commonly known glitches that should not be reported are avatars appearing twice in the topic list or private message, friends appearing more than once in the friend list, the edit icon showing next to a message when it shouldn't, and not being able to search for a forum after going back a page in the community.<br />
<br />
==== How do I format my post, e.g. bold text, add URLs, etc.? ====<br />
<br />
:AoPS is based on a markup language called BBCode. A tutorial of its functions on AoPS and how to use them can be found [[BBCode:Tutorial|here]].<br />
<br />
==== How do I hide content in the forums? ====<br />
:Wrap the content you want to hide in [hide] tags. This will make a clickable label that, once clicked, will reveal the content.<br />
[hide]Content[/hide]<br />
:If you want to customize the label, or have it says something other than "Click here to reveal hidden text", you can do something like:<br />
[hide=Label to display]Content[/hide]<br />
<br />
:Alternatively, wrap the content you want to hide in [tip] tags. This will make a hoverable label that, once hovered over, will reveal the content.<br />
[tip]Content[/tip]<br />
:If you want to customize the label, instead of saying "Hover for tip", you can do something like:<br />
[tip=Label to display]Content[/tip]<br />
<br />
====I got the message "Too many messages." when trying to send a private message, why?====<br />
:To prevent PM spam abuse like "hvbowibvibviorybvirusbshbiuovvisuvib", users with less than five forum posts are limited to four private messages within a forty-eight hour period.<br />
<br />
==== Posting often makes me a better user, right? ====<br />
<br />
:No. The quality of your posts matter far more than the number of posts you make. In fact, if you make too many unnecessary and spammy posts, you may find your posting privileges revoked.<br />
<br />
==== I have made some posts but my post count did not increase. Why? ====<br />
:Some forums, including the Test Forum, Mafia!, Fun Factory, The Learning Forum, and most user created forums, do not count toward total posts.<br />
<br />
==== I believe a post needs corrective action. What should I do? ====<br />
:If you believe a post needs moderative action, you may report it by clicking the <font face="aops">Z</font> icon on the upper-right corner of that post. If it's a minor mistake, you may want to PM the offending user instead and explain how they can make their post better.<br />
<br />
==== How do I post images? ====<br />
:While AoPS forums have the ability to attach images, we do not generally recommend doing so, as we can not guarantee the images will be available through upgrades, restorations, etc. We also have limited disk space which causes us to remove attachments from time to time. Therefore, we recommend using a third party image hosting solution. There are many options, but we recommend imgur.com.<br />
<br />
:* Go to https://imgur.com<br />
:* Click New Post<br />
:* Upload your image<br />
:* Mouse over image<br />
:* Click the 3 dots in upper right corner<br />
:* Click <b>Get Share Links</b><br />
:* Find the BBCode option and click the green Copy Link button<br />
:* Paste the copied info into your forum or blog post.<br />
<br />
Or, if you are using an online picture you can right click on it, click inspect, get the image link (usually ends in '.jpg') and paste it into AoPS [img][/img] tags.<br />
<br />
====How do I become a moderator of a forum?====<br />
:The creators of user-created forums select moderators in several different ways. Contact the creator(s) of the forum for more information.<br />
<br />
== Blogs ==<br />
==== How come I can't create a blog? ====<br />
:In order to be able to create a blog on AoPS, you must be a member of the community for at least 2 weeks, before creating any sort of blog, forum, or etc.<br />
<br />
==== How do I make my blog look nice? ====<br />
:Many AoPSers make their blogs look nice by applying CSS, which is a high-level stylesheet language. This can be done by typing code into the CSS box in the Blog Control Panel.<br />
:Try copying CSS of other blogs but give them credit!<br />
<br />
==== Blog Settings ====<br />
:The maximum amount of characters for the Post Comment Text, Comments Text, One Comment Text, and No Comments Text is '''40 characters'''<br />
<br />
== Alcumus ==<br />
<br />
==== How is rating computed? ====<br />
:The rating is more of a prediction of what percentage of problems in the topic the Alcumus engine believes you will get correct. As you get more and more correct, the rating will go up slower and slower. However, if you are predicted to get most correct, and you miss one or two problems, the rating, or prediction of percentage correct, will go down.<br />
<br />
==== I am stuck on a problem, and changing the topic does not change the problem. ====<br />
:Alcumus provides review problems to make sure you still recall information learned from the past. You may not skip these problems.<br />
<br />
== Contests ==<br />
==== Where can I find past contest questions and solutions? ====<br />
:You can find them in the [http://www.artofproblemsolving.com/Forum/resources.php Contests] section.<br />
<br />
==== How do I get problems onto the contest page? ====<br />
<br />
:Make a topic for each question in the appropriate forum, copy/paste the urls to the National Olympiad. Your problems may eventually be submitted into the Contest page.<br />
<br />
==== What are the guidelines for posting problems to be added to the contests section? ====<br />
:Refer to the [http://www.artofproblemsolving.com/Forum/viewtopic.php?f=144&t=195579 guidelines in this post].<br />
<br />
==== Why are the contest collections missing many contest questions ? ====<br />
:Generally, it is because users have not yet posted them onto the wiki (translation difficulties, not having access to the actual problems, lack of interest, etc). If you have a copy, please post the problems in the Community Section! In some cases, however, problems may be missing due to copyright claims from maths organizations.<br />
<br />
====Where are all of the mock contests?====<br />
:User-generated mock contests are now in its separate subforum, [https://artofproblemsolving.com/community/c594864_aops_mock_contests AoPS Mock Contests]. Please use that forum for creating, hosting, participating in, or recruiting writers/test solvers for mock contests.<br />

:Otherwise, you can send an email to extensions@aops.com with your username, class name and ID (the number in the class page URL after https://artofproblemsolving.com/class/) and reason for extension. Someone should get back to you within a couple days.<br />
<br />
==== Why is my post in the AoPS schoolhouse too long? ====<br />
<br />
:The minimum number number of characters allowed in an individual post in the AoPS Schoolhouse is 8 characters. The maximum number of characters allowed in an individual post in the AoPS Schoolhouse is 512 characters.</div>Yelly314https://artofproblemsolving.com/wiki/index.php?title=AoPS_Wiki:FAQ&diff=134051AoPS Wiki:FAQ2020-09-25T18:06:36Z<p>Yelly314: /* Forums */</p>

<br />
This is a community created list of Frequently Asked Questions about Art of Problem Solving. If you have a request to edit or add a question on this page, please make it [http://www.artofproblemsolving.com/Forum/viewtopic.php?f=416&t=414129 here].<br />
<br />
== General==<br />
<br />
<br />
==== Can I change my username? ====<br />
<br />
: It is possible for you to contact AoPS and change your username. However, AoPS typically only changes usernames for privacy reasons (e.g., your current username reveals personal information) or if the username contains inappropriate content. AoPS will not change your username for other reasons (e.g., current username is too "cringy").<br />
<br />
==== What Will Happen to My Account if I change my username? ====<br />
In the extremely rare case that your username does get switched, your contribution history will not be transferred to your new account<br />
: *You will have the same AoPS friends, messages, and post in the my message section<br />
: *Your scores or data for Reaper, Greed Control, and For The Win will be transferred to your new account<br />
: *Your account information will update for AoPS Academy and Beast Academy<br />
<br />
==== Why can't I change my avatar? ====<br />
: You must be a user for two weeks before changing your avatar. You can customize your avatar by downloading a picture and changing the dimensions via computer; however, it's really hard to get a good-looking picture under the size limit. Instead, you could visit one of the many avatar shops to get one (try searching "avatar shop" in other forums on the community page).<br />
<br />
==== Something looks weird (e.g., blurry, missing line, etc.) ====<br />
<br />
:This likely to be because of zoom-in area. Please make sure your zoom level is at 100% or is reset for correct rendering of the web page. If it is at 100% and still doesn't look right, try to refresh or hard refresh. If it still continues looking weird, follow the instructions [https://artofproblemsolving.com/community/c10h1076079_red_me_first__how_to_write_a_bug_report here] to submit a bug report about it in Site Support.<br />
<br />
==== Can I make more than one account?==== <br />
<br />
: Short answer: No.<br />
<br />
: Long answer: Multiple accounts (multis) are banned on AoPS. Having more than one account leads to issues of not remembering on what account you did what. Using multiple accounts in an attempt to "game" the system, (e.g. reaper in some way) or otherwise violate the ToS without consequences will lead to all or some of your accounts being deactivated. If you have already made additional accounts, please choose one account and stop using the others.<br />
<br />
====What software does Art of Problem Solving use to run the website?====<br />
<br />
:* Search: Solr<br />
:* Wiki: MediaWiki<br />
:* Asymptote and <math>\text{\LaTeX}</math> are generated through their respective binary packages<br />
:* Videos: YouTube<br />
:* PyWindow: Skulpt<br />
<br />
:All other parts of the website are custom built.<br />
<br />
== Forums ==<br />
<br />
====How do I create a forum?====<br />
<br />
:To create an AoPS forum, a user must be on the AoPS community for at least 2 weeks. To create a forum, hover over the community tab, then click "My AoPS." You should now see your avatar, along with your profile info, and a list of your friends. Now, click on the "My Forums" tab. There, you would be able to see which forum you moderate or administrate, as well as the private forums you can access. Click on the "+" button at the top right. This should lead you to a forum creating page.<br />
<br />
:Your forum name must be unique and it must be 50 characters or less and your forum description must be 240 characters or less.<br />
<br />
====Why do some posts say they were posted in the future?====<br />
:The AoPS clock is based on the official Naval Observatory time. This is considered the most accurate time. If your computer's system clock is behind the correct time, recent posts may indicate they were posted in the future. Please correct your computer's clock or enable clock synchronization so that your clock is always correct. Mac users may wish to check [http://www.macinstruct.com/node/92 Synchronize your Mac's Clock With A Time Server]. You can also check [http://www.time.gov the US offical time] which will also show you how much your clock is off.<br />
<br />
====Why do some threads have less posts than the number of the latest post?====<br />
:This is because of deleted posts. When posts get deleted, their post number is not reused.<br />
<br />
====I've lost admin access to a forum or blog I created, how do I get it back?====<br />
:Please send an email to sheriff@aops.com with the issue and URL of your forum. They will research your request and restore admin access to your forum if appropriate.<br />
<br />
====What should I do if I find a glitch in the community?====<br />
:First, search the Site Support forum to check if your issue has already been reported.<br />
<br />
:If your issue isn't reported, try refreshing your browser page. Most issues go away after a refresh and there is no need to report the issue unless it continues after you refresh your browser. You can refresh on most browsers in Windows and Chrome OS with Ctrl + R and on Mac with Cmd + R. To Hard Refresh, click Shift between Ctrl/Cmd and R.<br />
<br />
:Some commonly known glitches that should not be reported are avatars appearing twice in the topic list or private message, friends appearing more than once in the friend list, the edit icon showing next to a message when it shouldn't, and not being able to search for a forum after going back a page in the community.<br />
<br />
==== How do I format my post, e.g. bold text, add URLs, etc.? ====<br />
<br />
:AoPS is based on a markup language called BBCode. A tutorial of its functions on AoPS and how to use them can be found [[BBCode:Tutorial|here]].<br />
<br />
==== How do I hide content in the forums? ====<br />
:Wrap the content you want to hide in [hide] tags. This will make a clickable label that, once clicked, will reveal the content.<br />
[hide]Content[/hide]<br />
:If you want to customize the label, or have it says something other than "Click here to reveal hidden text", you can do something like:<br />
[hide=Label to display]Content[/hide]<br />
<br />
:Alternatively, wrap the content you want to hide in [tip] tags. This will make a hoverable label that, once hovered over, will reveal the content.<br />
[tip]Content[/tip]<br />
:If you want to customize the label, instead of saying "Hover for tip", you can do something like:<br />
[tip=Label to display]Content[/tip]<br />
<br />
====I got the message "Too many messages." when trying to send a private message, why?====<br />
:To prevent PM spam abuse like "hvbowibvibviorybvirusbshbiuovvisuvib", users with less than five forum posts are limited to four private messages within a forty-eight hour period.<br />
<br />
==== Posting often makes me a better user, right? ====<br />
<br />
No. The quality of your posts matter far more than the number of posts you make. In fact, if you make too many unnecessary and spammy posts, you may find your posting privileges revoked.<br />
<br />
==== I have made some posts but my post count did not increase. Why? ====<br />
:Some forums, including the Test Forum, Mafia!, Fun Factory, The Learning Forum, and most user created forums, do not count toward total posts.<br />
<br />
==== I believe a post needs corrective action. What should I do? ====<br />
:If you believe a post needs moderative action, you may report it by clicking the <font face="aops">Z</font> icon on the upper-right corner of that post. If it's a minor mistake, you may want to PM the offending user instead and explain how they can make their post better.<br />
<br />
==== How do I post images? ====<br />
:While AoPS forums have the ability to attach images, we do not generally recommend doing so, as we can not guarantee the images will be available through upgrades, restorations, etc. We also have limited disk space which causes us to remove attachments from time to time. Therefore, we recommend using a third party image hosting solution. There are many options, but we recommend imgur.com.<br />
<br />
:* Go to https://imgur.com<br />
:* Click New Post<br />
:* Upload your image<br />
:* Mouse over image<br />
:* Click the 3 dots in upper right corner<br />
:* Click <b>Get Share Links</b><br />
:* Find the BBCode option and click the green Copy Link button<br />
:* Paste the copied info into your forum or blog post.<br />
<br />
Or, if you are using an online picture you can right click on it, click inspect, get the image link (usually ends in '.jpg') and paste it into AoPS [img][/img] tags.<br />
<br />
====How do I become a moderator of a forum?====<br />
:The creators of user-created forums select moderators in several different ways. Contact the creator(s) of the forum for more information.<br />
<br />
== Blogs ==<br />
==== How come I can't create a blog? ====<br />
:In order to be able to create a blog on AoPS, you must be a member of the community for at least 2 weeks, before creating any sort of blog, forum, or etc.<br />
<br />
==== How do I make my blog look nice? ====<br />
:Many AoPSers make their blogs look nice by applying CSS, which is a high-level stylesheet language. This can be done by typing code into the CSS box in the Blog Control Panel.<br />
:Try copying CSS of other blogs but give them credit!<br />
<br />
==== Blog Settings ====<br />
:The maximum amount of characters for the Post Comment Text, Comments Text, One Comment Text, and No Comments Text is '''40 characters'''<br />
<br />
== Alcumus ==<br />
<br />
==== How is rating computed? ====<br />
:The rating is more of a prediction of what percentage of problems in the topic the Alcumus engine believes you will get correct. As you get more and more correct, the rating will go up slower and slower. However, if you are predicted to get most correct, and you miss one or two problems, the rating, or prediction of percentage correct, will go down.<br />
<br />
==== I am stuck on a problem, and changing the topic does not change the problem. ====<br />
:Alcumus provides review problems to make sure you still recall information learned from the past. You may not skip these problems.<br />
<br />
== Contests ==<br />
==== Where can I find past contest questions and solutions? ====<br />
:You can find them in the [http://www.artofproblemsolving.com/Forum/resources.php Contests] section.<br />
<br />
==== How do I get problems onto the contest page? ====<br />
<br />
:Make a topic for each question in the appropriate forum, copy/paste the urls to the National Olympiad. Your problems may eventually be submitted into the Contest page.<br />
<br />
==== What are the guidelines for posting problems to be added to the contests section? ====<br />
:Refer to the [http://www.artofproblemsolving.com/Forum/viewtopic.php?f=144&t=195579 guidelines in this post].<br />
<br />
==== Why are the contest collections missing many contest questions ? ====<br />
:Generally, it is because users have not yet posted them onto the wiki (translation difficulties, not having access to the actual problems, lack of interest, etc). If you have a copy, please post the problems in the Community Section! In some cases, however, problems may be missing due to copyright claims from maths organizations.<br />
<br />
====Where are all of the mock contests?====<br />
:User-generated mock contests are now in its separate subforum, [https://artofproblemsolving.com/community/c594864_aops_mock_contests AoPS Mock Contests]. Please use that forum for creating, hosting, participating in, or recruiting writers/test solvers for mock contests.<br />
<br />
====How can I host a mock contest?====<br />
:See posts on [https://artofproblemsolving.com/community/c594864h1168324_hi__im_interested_in_writing_a_mock_contest writing a mock contest] and [https://artofproblemsolving.com/community/c594864h1349281_tips_for_organizing_a_mock_contest Tips for Organizing a Mock Contest].<br />

This is a community created list of Frequently Asked Questions about Art of Problem Solving. If you have a request to edit or add a question on this page, please make it [http://www.artofproblemsolving.com/Forum/viewtopic.php?f=416&t=414129 here].<br />
<br />
== General==<br />
<br />
<br />
==== Can I change my username? ====<br />
<br />
: It is possible for you to contact AoPS and change your username. However, AoPS typically only changes usernames for privacy reasons (e.g., your current username reveals personal information) or if the username contains inappropriate content. AoPS will not change your username for other reasons (e.g., current username is too "cringy").<br />
<br />
==== What Will Happen to My Account if I change my username? ====<br />
In the extremely rare case that your username does get switched, your contribution history will not be transferred to your new account<br />
: *You will have the same AoPS friends, messages, and post in the my message section<br />
: *Your scores or data for Reaper, Greed Control, and For The Win will be transferred to your new account<br />
: *Your account information will update for AoPS Academy and Beast Academy<br />
<br />
==== Why can't I change my avatar? ====<br />
: You must be a user for two weeks before changing your avatar. You can customize your avatar by downloading a picture and changing the dimensions via computer; however, it's really hard to get a good-looking picture under the size limit. Instead, you could visit one of the many avatar shops to get one (try searching "avatar shop" in other forums on the community page).<br />
<br />
==== Something looks weird (e.g., blurry, missing line, etc.) ====<br />
<br />
:This likely to be because of zoom-in area. Please make sure your zoom level is at 100% or is reset for correct rendering of the web page. If it is at 100% and still doesn't look right, try to refresh or hard refresh. If it still continues looking weird, follow the instructions [https://artofproblemsolving.com/community/c10h1076079_red_me_first__how_to_write_a_bug_report here] to submit a bug report about it in Site Support.<br />
<br />
==== Can I make more than one account?==== <br />
<br />
: Short answer: No.<br />
<br />
: Long answer: Multiple accounts (multis) are banned on AoPS. Having more than one account leads to issues of not remembering on what account you did what. Using multiple accounts in an attempt to "game" the system, (e.g. reaper in some way) or otherwise violate the ToS without consequences will lead to all or some of your accounts being deactivated. If you have already made additional accounts, please choose one account and stop using the others.<br />
<br />
====What software does Art of Problem Solving use to run the website?====<br />
<br />
:* Search: Solr<br />
:* Wiki: MediaWiki<br />
:* Asymptote and <math>\text{\LaTeX}</math> are generated through their respective binary packages<br />
:* Videos: YouTube<br />
:* PyWindow: Skulpt<br />
<br />
:All other parts of the website are custom built.<br />
<br />
== Forums ==<br />
<br />
====How do I create a forum?====<br />
<br />
:To create an AoPS forum, a user must be on the AoPS community for at least 2 weeks. To create a forum, hover over the community tab, then click "My AoPS." You should now see your avatar, along with your profile info, and a list of your friends. Now, click on the "My Forums" tab. There, you would be able to see which forum you moderate or administrate, as well as the private forums you can access. Click on the "+" button at the top right. This should lead you to a forum creating page.<br />
<br />
:Your forum name must be unique and it must be 50 characters or less and your forum description must be 240 characters or less.<br />
<br />
====Why do some posts say they were posted in the future?====<br />
:The AoPS clock is based on the official Naval Observatory time. This is considered the most accurate time. If your computer's system clock is behind the correct time, recent posts may indicate they were posted in the future. Please correct your computer's clock or enable clock synchronization so that your clock is always correct. Mac users may wish to check [http://www.macinstruct.com/node/92 Synchronize your Mac's Clock With A Time Server]. You can also check [http://www.time.gov the US offical time] which will also show you how much your clock is off.<br />
<br />
====Why do some threads have less posts than the number of the latest post?====<br />
This is because of deleted posts. When posts get deleted, their post number is not reused.<br />
<br />
====I've lost admin access to a forum or blog I created, how do I get it back?====<br />
:Please send an email to sheriff@aops.com with the issue and URL of your forum. They will research your request and restore admin access to your forum if appropriate.<br />
<br />
====What should I do if I find a glitch in the community?====<br />
:First, search the Site Support forum to check if your issue has already been reported.<br />
<br />
:If your issue isn't reported, try refreshing your browser page. Most issues go away after a refresh and there is no need to report the issue unless it continues after you refresh your browser. You can refresh on most browsers in Windows and Chrome OS with Ctrl + R and on Mac with Cmd + R. To Hard Refresh, click Shift between Ctrl/Cmd and R.<br />
<br />
:Some commonly known glitches that should not be reported are avatars appearing twice in the topic list or private message, friends appearing more than once in the friend list, the edit icon showing next to a message when it shouldn't, and not being able to search for a forum after going back a page in the community.<br />
<br />
==== How do I format my post, e.g. bold text, add URLs, etc.? ====<br />
<br />
:AoPS is based on a markup language called BBCode. A tutorial of its functions on AoPS and how to use them can be found [[BBCode:Tutorial|here]].<br />
<br />
==== How do I hide content in the forums? ====<br />
:Wrap the content you want to hide in [hide] tags. This will make a clickable label that, once clicked, will reveal the content.<br />
[hide]Content[/hide]<br />
:If you want to customize the label, or have it says something other than "Click here to reveal hidden text", you can do something like:<br />
[hide=Label to display]Content[/hide]<br />
<br />
:Alternatively, wrap the content you want to hide in [tip] tags. This will make a hoverable label that, once hovered over, will reveal the content.<br />
[tip]Content[/tip]<br />
:If you want to customize the label, instead of saying "Hover for tip", you can do something like:<br />
[tip=Label to display]Content[/tip]<br />
<br />
====I got the message "Too many messages." when trying to send a private message, why?====<br />
:To prevent PM spam abuse like "hvbowibvibviorybvirusbshbiuovvisuvib", users with less than five forum posts are limited to four private messages within a forty-eight hour period.<br />
<br />
==== Posting often makes me a better user, right? ====<br />
<br />
No. The quality of your posts matter far more than the number of posts you make. In fact, if you make too many unnecessary and spammy posts, you may find your posting privileges revoked.<br />
<br />
==== I have made some posts but my post count did not increase. Why? ====<br />
:Some forums, including the Test Forum, Mafia!, Fun Factory, The Learning Forum, and most user created forums, do not count toward total posts.<br />
<br />
==== I believe a post needs corrective action. What should I do? ====<br />
:If you believe a post needs moderative action, you may report it by clicking the <font face="aops">Z</font> icon on the upper-right corner of that post. If it's a minor mistake, you may want to PM the offending user instead and explain how they can make their post better.<br />
<br />
==== How do I post images? ====<br />
:While AoPS forums have the ability to attach images, we do not generally recommend doing so, as we can not guarantee the images will be available through upgrades, restorations, etc. We also have limited disk space which causes us to remove attachments from time to time. Therefore, we recommend using a third party image hosting solution. There are many options, but we recommend imgur.com.<br />
<br />
:* Go to https://imgur.com<br />
:* Click New Post<br />
:* Upload your image<br />
:* Mouse over image<br />
:* Click the 3 dots in upper right corner<br />
:* Click <b>Get Share Links</b><br />
:* Find the BBCode option and click the green Copy Link button<br />
:* Paste the copied info into your forum or blog post.<br />
<br />
Or, if you are using an online picture you can right click on it, click inspect, get the image link (usually ends in '.jpg') and paste it into AoPS [img][/img] tags.<br />
<br />
====How do I become a moderator of a forum?====<br />
:The creators of user-created forums select moderators in several different ways. Contact the creator(s) of the forum for more information.<br />
<br />
== Blogs ==<br />
==== How come I can't create a blog? ====<br />
:In order to be able to create a blog on AoPS, you must be a member of the community for at least 2 weeks, before creating any sort of blog, forum, or etc.<br />
<br />
==== How do I make my blog look nice? ====<br />
:Many AoPSers make their blogs look nice by applying CSS, which is a high-level stylesheet language. This can be done by typing code into the CSS box in the Blog Control Panel.<br />
:Try copying CSS of other blogs but give them credit!<br />
<br />
==== Blog Settings ====<br />
:The maximum amount of characters for the Post Comment Text, Comments Text, One Comment Text, and No Comments Text is '''40 characters'''<br />
<br />
== Alcumus ==<br />
<br />
==== How is rating computed? ====<br />
:The rating is more of a prediction of what percentage of problems in the topic the Alcumus engine believes you will get correct. As you get more and more correct, the rating will go up slower and slower. However, if you are predicted to get most correct, and you miss one or two problems, the rating, or prediction of percentage correct, will go down.<br />
<br />
==== I am stuck on a problem, and changing the topic does not change the problem. ====<br />
:Alcumus provides review problems to make sure you still recall information learned from the past. You may not skip these problems.<br />
<br />
== Contests ==<br />
==== Where can I find past contest questions and solutions? ====<br />
:You can find them in the [http://www.artofproblemsolving.com/Forum/resources.php Contests] section.<br />
<br />
==== How do I get problems onto the contest page? ====<br />
<br />
:Make a topic for each question in the appropriate forum, copy/paste the urls to the National Olympiad. Your problems may eventually be submitted into the Contest page.<br />
<br />
==== What are the guidelines for posting problems to be added to the contests section? ====<br />
:Refer to the [http://www.artofproblemsolving.com/Forum/viewtopic.php?f=144&t=195579 guidelines in this post].<br />
<br />
==== Why are the contest collections missing many contest questions ? ====<br />
:Generally, it is because users have not yet posted them onto the wiki (translation difficulties, not having access to the actual problems, lack of interest, etc). If you have a copy, please post the problems in the Community Section! In some cases, however, problems may be missing due to copyright claims from maths organizations.<br />
<br />
====Where are all of the mock contests?====<br />
:User-generated mock contests are now in its separate subforum, [https://artofproblemsolving.com/community/c594864_aops_mock_contests AoPS Mock Contests]. Please use that forum for creating, hosting, participating in, or recruiting writers/test solvers for mock contests.<br />
<br />
====How can I host a mock contest?====<br />

Please see the [//artofproblemsolving.com/ftw/faq For the Win! FAQ] for many common questions.<br />
<br />
== School ==<br />
<br />
==== What if I miss a class? ====<br />
:There are classroom transcripts available under My Classes, available at the top right of the web site. You can view these transcripts in order to review any missed material. You can also ask questions on the class message board. Don't worry, though, classroom participation usually isn't weighted heavily.<br />
<br />
==== Is there audio or video in class? ====<br />
:For classes that runs online normally, there is generally no audio or video in the class. The classes are generally text and image based, in an interactive chat room environment, which allows students to ask questions at any time during the class. However, for classes that usually run in the academy, because of the current pandemic, the classes needs to be ran online. To simulate the academy environment, classes will be run on Zoom instead of the AoPS Schoolhouse. As a result, audio will be required and video is recommended.<br />
<br />
==== What if I want to drop out of a class? ====<br />
:For any course with more than 2 classes, students can drop the course any time before the third class begins and receive a full refund. No drops are allowed after the third class has started. To drop the class, go to the My Classes section by clicking the My Classes link at the top-right of the website. Then find the area on the right side of the page that lets you drop the class. A refund will be processed within 10 business days.<br />
<br />
==== For my homework, there is supposed to be a green bar but it's orange, why? ====<br />
<br />
:The bar turns green if and only if the required writing problem(s) is/are attempted.<br />
<br />
==== I need more time for my homework, what should I do? ====<br />
<br />
:There is a "Request Extension" button in the homework tab of your class. This will automatically extend the due date to 2 days after the normal deadline. If you want more time you need to ask for it in the little comment box, stating the reason why you want the extension, and how much time you want. This request will be looked at by the teachers and they will decide if you get the extension or not. Note that you can only use this button 3 times. After, you will need administrator approval.<br />
:Otherwise, you can send an email to extensions@aops.com with your username, class name and ID (the number in the class page URL after https://artofproblemsolving.com/class/) and reason for extension. Someone should get back to you within a couple days.<br />
<br />
==== Why is my post in the AoPS schoolhouse too long? ====<br />
<br />
:The minimum number number of characters allowed in an individual post in the AoPS Schoolhouse is 8 characters. The maximum number of characters allowed in an individual post in the AoPS Schoolhouse is 512 characters.</div>Yelly314https://artofproblemsolving.com/wiki/index.php?title=AoPS_Wiki:FAQ&diff=134049AoPS Wiki:FAQ2020-09-25T18:06:00Z<p>Yelly314: /* Forums */</p>

:Some commonly known glitches that should not be reported are avatars appearing twice in the topic list or private message, friends appearing more than once in the friend list, the edit icon showing next to a message when it shouldn't, and not being able to search for a forum after going back a page in the community.<br />
<br />
==== How do I format my post, e.g. bold text, add URLs, etc.? ====<br />
<br />
:AoPS is based on a markup language called BBCode. A tutorial of its functions on AoPS and how to use them can be found [[BBCode:Tutorial|here]].<br />
<br />
==== How do I hide content in the forums? ====<br />
:Wrap the content you want to hide in [hide] tags. This will make a clickable label that, once clicked, will reveal the content.<br />
[hide]Content[/hide]<br />
:If you want to customize the label, or have it says something other than "Click here to reveal hidden text", you can do something like:<br />
[hide=Label to display]Content[/hide]<br />
<br />
:Alternatively, wrap the content you want to hide in [tip] tags. This will make a hoverable label that, once hovered over, will reveal the content.<br />
[tip]Content[/tip]<br />
:If you want to customize the label, instead of saying "Hover for tip", you can do something like:<br />
[tip=Label to display]Content[/tip]<br />
<br />
====I got the message "Too many messages." when trying to send a private message, why?====<br />
:To prevent PM spam abuse like "hvbowibvibviorybvirusbshbiuovvisuvib", users with less than five forum posts are limited to four private messages within a forty-eight hour period.<br />
<br />
==== Posting often makes me a better user, right? ====<br />
<br />
No. The quality of your posts matter far more than the number of posts you make. In fact, if you make too many unnecessary and spammy posts, you may find your posting privileges revoked.<br />
<br />
==== I have made some posts but my post count did not increase. Why? ====<br />
:Some forums, including the Test Forum, Mafia!, Fun Factory, The Learning Forum, and most user created forums, do not count toward total posts.<br />
<br />
==== I believe a post needs corrective action. What should I do? ====<br />
:If you believe a post needs moderative action, you may report it by clicking the <font face="aops">Z</font> icon on the upper-right corner of that post. If it's a minor mistake, you may want to PM the offending user instead and explain how they can make their post better.<br />
<br />
==== How do I post images? ====<br />
:While AoPS forums have the ability to attach images, we do not generally recommend doing so, as we can not guarantee the images will be available through upgrades, restorations, etc. We also have limited disk space which causes us to remove attachments from time to time. Therefore, we recommend using a third party image hosting solution. There are many options, but we recommend imgur.com.<br />
<br />
:* Go to https://imgur.com<br />
:* Click New Post<br />
:* Upload your image<br />
:* Mouse over image<br />
:* Click the 3 dots in upper right corner<br />
:* Click <b>Get Share Links</b><br />
:* Find the BBCode option and click the green Copy Link button<br />
:* Paste the copied info into your forum or blog post.<br />
<br />
Or, if you are using an online picture you can right click on it, click inspect, get the image link (usually ends in '.jpg') and paste it into AoPS [img][/img] tags.<br />
<br />
====How do I become a moderator of a forum?====<br />
:The creators of user-created forums select moderators in several different ways. Contact the creator(s) of the forum for more information.<br />
<br />
== Blogs ==<br />
==== How come I can't create a blog? ====<br />
:In order to be able to create a blog on AoPS, you must be a member of the community for at least 2 weeks, before creating any sort of blog, forum, or etc.<br />
<br />
==== How do I make my blog look nice? ====<br />
:Many AoPSers make their blogs look nice by applying CSS, which is a high-level stylesheet language. This can be done by typing code into the CSS box in the Blog Control Panel.<br />
:Try copying CSS of other blogs but give them credit!<br />
<br />
==== Blog Settings ====<br />
:The maximum amount of characters for the Post Comment Text, Comments Text, One Comment Text, and No Comments Text is '''40 characters'''<br />
<br />
== Alcumus ==<br />
<br />
==== How is rating computed? ====<br />
:The rating is more of a prediction of what percentage of problems in the topic the Alcumus engine believes you will get correct. As you get more and more correct, the rating will go up slower and slower. However, if you are predicted to get most correct, and you miss one or two problems, the rating, or prediction of percentage correct, will go down.<br />
<br />
==== I am stuck on a problem, and changing the topic does not change the problem. ====<br />
:Alcumus provides review problems to make sure you still recall information learned from the past. You may not skip these problems.<br />
<br />
== Contests ==<br />
==== Where can I find past contest questions and solutions? ====<br />
:You can find them in the [http://www.artofproblemsolving.com/Forum/resources.php Contests] section.<br />
<br />
==== How do I get problems onto the contest page? ====<br />
<br />
:Make a topic for each question in the appropriate forum, copy/paste the urls to the National Olympiad. Your problems may eventually be submitted into the Contest page.<br />
<br />
==== What are the guidelines for posting problems to be added to the contests section? ====<br />
:Refer to the [http://www.artofproblemsolving.com/Forum/viewtopic.php?f=144&t=195579 guidelines in this post].<br />
<br />
==== Why are the contest collections missing many contest questions ? ====<br />
:Generally, it is because users have not yet posted them onto the wiki (translation difficulties, not having access to the actual problems, lack of interest, etc). If you have a copy, please post the problems in the Community Section! In some cases, however, problems may be missing due to copyright claims from maths organizations.<br />
<br />
====Where are all of the mock contests?====<br />
:User-generated mock contests are now in its separate subforum, [https://artofproblemsolving.com/community/c594864_aops_mock_contests AoPS Mock Contests]. Please use that forum for creating, hosting, participating in, or recruiting writers/test solvers for mock contests.<br />

<br />
Please see the [//artofproblemsolving.com/ftw/faq For the Win! FAQ] for many common questions.<br />
<br />
== School ==<br />
<br />
==== What if I miss a class? ====<br />
:There are classroom transcripts available under My Classes, available at the top right of the web site. You can view these transcripts in order to review any missed material. You can also ask questions on the class message board. Don't worry, though, classroom participation usually isn't weighted heavily.<br />
<br />
==== Is there audio or video in class? ====<br />
:For classes that runs online normally, there is generally no audio or video in the class. The classes are generally text and image based, in an interactive chat room environment, which allows students to ask questions at any time during the class. However, for classes that usually run in the academy, because of the current pandemic, the classes needs to be ran online. To simulate the academy environment, classes will be run on Zoom instead of the AoPS Schoolhouse. As a result, audio will be required and video is recommended.<br />
<br />
==== What if I want to drop out of a class? ====<br />
:For any course with more than 2 classes, students can drop the course any time before the third class begins and receive a full refund. No drops are allowed after the third class has started. To drop the class, go to the My Classes section by clicking the My Classes link at the top-right of the website. Then find the area on the right side of the page that lets you drop the class. A refund will be processed within 10 business days.<br />
<br />
==== For my homework, there is supposed to be a green bar but it's orange, why? ====<br />
<br />
:The bar turns green if and only if the required writing problem(s) is/are attempted.<br />
<br />
==== I need more time for my homework, what should I do? ====<br />
<br />
:There is a "Request Extension" button in the homework tab of your class. This will automatically extend the due date to 2 days after the normal deadline. If you want more time you need to ask for it in the little comment box, stating the reason why you want the extension, and how much time you want. This request will be looked at by the teachers and they will decide if you get the extension or not. Note that you can only use this button 3 times. After, you will need administrator approval.<br />
:Otherwise, you can send an email to extensions@aops.com with your username, class name and ID (the number in the class page URL after https://artofproblemsolving.com/class/) and reason for extension. Someone should get back to you within a couple days.<br />
<br />
==== Why is my post in the AoPS schoolhouse too long? ====<br />
<br />
:The minimum number number of characters allowed in an individual post in the AoPS Schoolhouse is 8 characters. The maximum number of characters allowed in an individual post in the AoPS Schoolhouse is 512 characters.</div>Yelly314https://artofproblemsolving.com/wiki/index.php?title=Math_Jam&diff=132253Math Jam2020-08-20T20:20:43Z<p>Yelly314: </p>

<hr />
<div>AoPS Schoolhouse is the system used for [[Math Jam|MathJams]] and online school. The instructors are able to type what they need to and send it out to everyone. Usually, there are more than one instructor. The main instructor is responsible for posting the learning materials, other moderators serve as backup if the main instructor cannot make it to class or has to leave during a class. Some moderators will also answer questions posted by students. For example, in [[The World’s Largest Countdown Round]], there were 17 moderators.<br />
<br />
==Posting==<br />
If the chatroom is moderated, which is always the case during class and usually the case during MathJams, when students type things into the chatroom, the message is going to go to the instructors. From there, the instructors have the choice of sharing the question with the class, whispering an answer back, or doing nothing. Your post will show up in the classroom in a green color if it is chosen. Other people's chosen posts will show up in a blue color. If you get a reply back in a whisper, it will show up in a pink or purple color. If a moderator feels a question requires further discussion, they will open a mini window with you to more deeply discuss the question.<br />
<br />
==Character Limit==<br />
The character limit for posts in the AoPS Schoolhouse is <b>512 characters</b>. You can split your posts into two to bypass this limit. There is no limit for the number of posts you can send. However, you could get a warning for posting spam messages.<br />
<br />
==Emojis==<br />
