==== Can I change my user name? ====
+
==== Can I change my username? ====
  
:As indicated during the time of your registration, you are unable to change your username.
+
: Yes, 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").
  
==== Can I make more than one account? ====
+
==== Why can't I change my profile picture? ====
 +
: If you are a new user less than 2 weeks old, you cannot change your profile in any way. You may also be profile picture banned, if your previous profile picture contained inappropriate content. Otherwise, contact AoPS.
  
:It is preferred that you have one and only one account. Having more leads to issues of not remembering on what account you did what. Using multiple accounts to "game" the system, (e.g., increase rating for posts or in online games) will lead to bans on all accounts associated to you. If you have already made additional accounts, please choose one account and stop using the others.
+
==== Something looks weird (e.g., blurry, missing line, etc.) ====
 +
 
 +
: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 not to refresh or hard refresh. If it still continues looking weird, follow the instructions [https://artofproblemsolving.com/community/c10h1076079_read_me_first__how_to_write_a_bug_report here] to submit a bug report about it in Site Support.
 +
 
 +
==== What is a 'multi' and can I have one? ====
 +
 
 +
:A multi stands for multiple accounts. You are not allowed to have multiple accounts; see [https://artofproblemsolving.com/wiki/index.php/AoPS_Wiki:FAQ#Can_I_make_more_than_one_account.3F here] for more info.
 +
 
 +
==== Can I make more than one account?====
 +
 
 +
: Short answer: No.
 +
 +
: 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 AoPS 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.
 +
 
 +
And, with more than one account, it may cause problems with the system and interfere with the programs that are running in the background to provide a seamless experience. And so, if you have another account that you are using in addition to the one that you already have, please, stop using it. It truly benefits all of us.

== Forums ==
 +
====Why can't I use a forum name (or description)?====
 +
:Your forum name must be unique and it must be between 3 and 50 characters and your forum description must be 240 characters or less.
  
====Can you make an AoPS App?====
+
====Why do some posts say they were posted in the future?====
 +
:The AoPS clock is based on the official Naval Observatory time, which 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]. Windows users can go [https://www.windowscentral.com/how-manage-time-servers-windows-10 here.] You can also check [http://www.time.gov the US official time] which will also show you how much your clock is off.
  
:There are currently no plans to build an app. Any app built would work almost identically to the website, and not be any faster, so there is little value in building an app.
+
====Why do some threads have fewer posts than the number of the latest post?====
 +
: This is because of deleted posts. When posts get deleted, their post number is not reused.
  
== Forums ==
+
====I've lost admin access to a forum or blog I created, how do I get it back?====
 +
:Please send an email to sheriff@artofproblemsolving.com with the issue and URL of your forum. They will research your request and restore admin access to your forum if appropriate.
 +
 
 +
====What should I do if I find a glitch in the community?====
 +
:First, search the Site Support forum to check if your issue has already been reported.
 +
 
 +
: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.
 +
 
 +
: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.

==== How do I hide content in the forums? ====
:Wrap the content you want to hide in [hide] tags.
+
:Wrap the content you want to hide in [hide] tags. This will make a clickable label that, once clicked, will reveal the content.
 
     [hide]Content[/hide]
 
     [hide]Content[/hide]
:If you want to customize the label, instead of saying "Click here to reveal hidden text", you can do something like:
+
:If you want to customize the label, or have it says something other than "Click to reveal hidden text", you can do something like:
     [hide=Label to display]Content[/hide]
+
     [hide="Label to display"]Content[/hide]
  
==== I got the message "You can not post at this time" when trying to post, why? ====
+
: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.
 
+
    [tip]Content[/tip]
:New users are not allowed to post messages with URLs and various other things. Once you have five posts you can post normally.
+
:If you want to customize the label, instead of saying "Hover for tip", you can do something like:
 +
    [tip="Label to display"]Content[/tip]
  
 
====I got the message "Too many messages." when trying to send a private message, why?====
 
====I got the message "Too many messages." when trying to send a private message, why?====
:To prevent PM spam abuse, users with less than five forum posts are limited to four private messages within a forty-eight hour period.
+
:To prevent PM spam abuse like "asdfghjklkjhgfdsasdfghjklkjhgfdsa", users with less than five forum posts are limited to four private messages within a forty-eight hour period.
  
==== If I make more posts, it means I'm a better user, right? ====
+
====How do you tell if someone has blocked private messages?====
 +
If you're not sure, try to private message them. It should say you can't. Or go to their user page. It should say so (Private message). Finally, you can check their posts, because generally you can private message about a post.
  
:Absolutely not. Post quality is far more important than post quantity. Users making a lot of senseless posts are often considered worse users, or spammers.
+
====How do you private message yourself?====
 +
If you want to private message yourself to remember something, you have to go to one of your posts, and click the PM button in the top right corner. Then you reach a private message screen where you can backspace the text and write your message.
  
==== I have made some posts but my post count did not increase. Why? ====
+
==== Posting often makes me a better user, right? ====
  
:When you post in some of the forums, such as the Test Forum, Mafia Forum, and the Fun Factory, it does not count towards your post count.
+
:It will depend. Often, it's just the opposite. The quality of your posts matters 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.
  
==== How does AoPS select moderators? ====
+
==== I have posted in a forum, but my post count did not increase. Why? ====
 +
:Some forums, including the Test Forum, Mafia, Fun Factory, and other user created forums, do not count toward total posts.
  
:When a new moderator is needed in the forums, AoPS administrators first check if any current moderators could serve as a moderator of the forum which needs a moderator. Should none be found, AoPS administrators and/or other moderators scour the forum looking for productive users. They may also ask for suggestions from other moderators or trusted users on the site. Once they have pinpointed a possible candidate based on their long term usage of the site, productive posts in the forum, and having no recent behavioral issues, that user is asked if he or she would like to moderate the forum.  
+
'''Please do not edit the Wiki just for advertising.
 +
I see you, Ultim@te G@mes staff members.
  
:Less active forums often have no moderator. Inappropriate posts should be reported by users and administrators will take appropriate action.
+
~SpeedCuber7'''
 
 
:AoPS receives MANY requests to be a moderator. As they receive so many, it is possible that you won't get a response should you request to be one. Also, AoPS very rarely makes someone a mod for asking to be one, so '''please do not ask'''.
 
  
 
==== I believe a post needs corrective action. What should I do? ====
 
==== I believe a post needs corrective action. What should I do? ====
 +
: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.
  
:If you believe a post needs moderative action, you may report it by clicking the "!" 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. Usually, you shouldn't publicly post such things on a thread itself, which is called "backseat moderation" and is considered rude.
+
==== How do I post images? ====
 +
: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.
  
==== How long of a non-commented thread is considered reviving? ====
+
:* Go to https://imgur.com/upload
 +
:* Upload your image, and wait for it to complete
 +
:* Hover your cursor over the image
 +
:* Click the 3 dots in the upper right corner
 +
:* Click <b>Get Share Links</b>
 +
:* Find the BBCode option, which should start with "[img]", and click the green <b>Copy Link</b> button
 +
:* Paste the copied text into your forum or blog post.
  
:If any post is still on-topic and isn't spammy or anything, it isn't considered reviving.  However, everyone has a different period of time that they consider reviving. In general, apply common sense.
+
:In general, if you have any online image that you want to post, you can right-click on it, click <b>copy image address</b>, and paste it into AoPS, in between an [img][/img] tags.
  
==== Someone is marking all my posts as spam, what should I do? ====
+
====How do I become a moderator of a forum?====
 +
:The creators of user-created forums select moderators in several different ways. Contact the creator(s) of the forum for information.
 +
:To see the list of moderators, click the little <b>i</b> icon on the slight-upper-left corner, next to where the name of that forum is.
 +
:If you are the creator, and want to know how to make a user a moderator, follow these steps:
  
:It happens to everyone. There's really not much you can do.
+
:* Click the little <b>i</b> icon on the slight-upper-left corner, next to where the name of that forum is.
 +
:* Below the <b>Permissions</b> section, there should be a list of moderators. Click the pencil button to edit.
  
==== Are posts marked spam more often than good? ====
+
====Many users often ask and talk about "forum rankings." How do I see it?====
 +
:Forum rankings are how forums are ranked. There is no confirmation from a site administrator on how these are ranked, but most users suspect that they are ranked on activity.
 +
:Here is how to view forum rankings:
 +
:* Go the the community.
 +
:* Scroll down to the section <b>Other Forums and Collections</b>
 +
:* In that section, find the folder <b>Other Forums</b>. The direct link is https://artofproblemsolving.com/community/c9
 +
:* Scroll down the first few rows of forums until you reach a forum called <b>College</b>
 +
:* Every forum after that is user-created and ranked. The first forum after <b>College</b> is the first in rankings, the second one is second, third one is third(user created forums usually) etc.
  
:No.
+
== Blogs ==
 +
==== How come I can't create a blog? ====
 +
:In order to be able to create a blog on AoPS, you have to be a member of the community for at least 2 weeks, before creating any sort of blog, forum, or etc.
  
==== How do I post images? ====
+
==== How do I make my blog look nice? ====
 +
: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.
 +
:Try copying CSS of other blogs but remember to give them credit!
  
: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.
+
==== Blog Settings ====
 +
:The maximum amount of characters for the Post Comment Text, Comments Text, One Comment Text, and No Comments Text is '''40 characters'''.
  
:* Go to imgur.com
+
==== Why are usernames a different color? ====
:* Click upload images
+
Blogs use a different stylesheet than the rest of the site and blog owners can customize their blog, including some portions of the feed widget, and therefore usernames show differently in a blog than on the community. Additionally, in the forums, black means a regular user, green means a moderator, red means an administrator, and blue means Site Admin.
:* Follow the on screen instructions to upload the image to imgur.
+
== Alcumus ==
:* After uploading, you'll be presented the uploaded image along with links on the left.
 
:* Find the link labeled BBCode (message boards & forums)
 
:* Copy the code, and paste into your post. It will look something like:
 
  
    [img]http://i.imgur.com/aBcDeFgH.jpg[/img]
+
==== How is rating computed? ====
 +
: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.
  
== Blogs ==
+
==== I am stuck on a problem, and changing the topic does not change the problem. ====
==== How come I can't create a blog? ====
+
:Alcumus provides review problems to make sure you still recall information learned from the past. These problems cannot be skipped unless you go to an entirely different subject.
:One needs to have at least 5 posts in order to make a blog.
 
==== How do I make my blog look nice? ====
 
:Many AoPSers make their blogs look awesome by applying [[CSS|CSS]], which is a high-level stylesheet language. This can be done by typing CSS code into the CSS box in the Blog Control Panel.

==== How do you access FTW? ====
+
Please see the [https://artofproblemsolving.com/ftw/ftw For the Win! FAQ] for many common questions. (To get to the FAQ, click on the three lines in the top left and then on FAQ).
You can access FTW by clicking For the Win! from the Resources menu at the top of the page.
 
  
==== Did FTW miscount my number of games?====
+
== School ==
  
No! However, the (Overall) rating statistics do not count games with less than 6 problems or less than 15 seconds.
+
Please refer to the [https://artofproblemsolving.com/school/handbook AoPS Classes Handbook] in the dropdown menu under "ONLINE SCHOOL."
  
For example, if you have played 30 games, but not all of them were 6 problems or higher, then you will still be muted.
+
==== What if I miss a class? ====
 +
: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. Keep in mind, though, that whispers (Things the instructors say to you, and only you, to help you understand stuff) won't be shown, and you won't get to ask questions. However, class moves quicker! You can also ask questions on the class message board. Don't worry, though, classroom participation usually isn't weighted heavily.
  
== School ==
+
==== Is there audio or video in class? ====
 +
: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. Classes taken at the AoPS Academy Virtual Campus will have video. During the COVID-19 crisis, all AoPS Academy classes are running online using the Zoom video conferencing platform. However, there are AoPS videos with audio in some classes, and they can be very helpful, in case the class material doesn't seem easy.
  
 
==== What if I want to drop out of a class? ====
 
==== What if I want to drop out of a class? ====
 
: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.

:The bar turns green if and only if the required writing problems are saved.
 +
 
 +
==== I need more time for my homework, how to get it? ====
 +
 
 +
:There is a "Request Extension" button in the homework tab of your class.  This will automatically extend the due date to 1-3 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 2-4 times depending on how many weeks your class is. After, you will need administrator approval.
 +
: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.
  
==== Is there audio or video in class? ====
+
==== Why is my post in the AoPS schoolhouse too long? ====
:There is generally no audio or video in the class. The classes are generally completely text based, in an interactive chat room environment, which allows students to ask questions at any time during the class. In addition to audio and video limiting interactivity, the technology isn't quite there yet for all students to be able to adequately receive streaming audio and video.
 
  
====I feel like joining! What are my class choices? ====
+
:The minimum number of characters allowed in an individual post in the AoPS Schoolhouse is 1 character. The maximum number of characters allowed in an individual post in the AoPS Schoolhouse is 512 characters.

General

Can I change my username?

Yes, 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").

Why can't I change my profile picture?

If you are a new user less than 2 weeks old, you cannot change your profile in any way. You may also be profile picture banned, if your previous profile picture contained inappropriate content. Otherwise, contact AoPS.

Something looks weird (e.g., blurry, missing line, etc.)

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 not to refresh or hard refresh. If it still continues looking weird, follow the instructions here to submit a bug report about it in Site Support.

What is a 'multi' and can I have one?

A multi stands for multiple accounts. You are not allowed to have multiple accounts; see here for more info.

Can I make more than one account?

Short answer: No.
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 AoPS 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.

And, with more than one account, it may cause problems with the system and interfere with the programs that are running in the background to provide a seamless experience. And so, if you have another account that you are using in addition to the one that you already have, please, stop using it. It truly benefits all of us.

What software does Art of Problem Solving use to run the website?

  • Search: Solar
  • Wiki: MediaWiki
  • Asymptote and Latex are generated through their respective binary packages
  • Videos: YouTube
  • PyWindow: Skulpt
  • Classroom and Reaper: Socket.IO
All other parts of the website are custom built.

Forums

Why can't I use a forum name (or description)?

Your forum name must be unique and it must be between 3 and 50 characters and your forum description must be 240 characters or less.

Why do some posts say they were posted in the future?

The AoPS clock is based on the official Naval Observatory time, which 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 Synchronize your Mac's Clock With A Time Server. Windows users can go here. You can also check the US official time which will also show you how much your clock is off.

Why do some threads have fewer posts than the number of the latest post?

This is because of deleted posts. When posts get deleted, their post number is not reused.

I've lost admin access to a forum or blog I created, how do I get it back?

Please send an email to sheriff@artofproblemsolving.com with the issue and URL of your forum. They will research your request and restore admin access to your forum if appropriate.

What should I do if I find a glitch in the community?

First, search the Site Support forum to check if your issue has already been reported.
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.
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.

How do I format my post, e.g. bold text, add URLs, etc.?

AoPS is based on a markup language called BBCode. A tutorial of its functions on AoPS and how to use them can be found here.

How do I hide content in the forums?

Wrap the content you want to hide in [hide] tags. This will make a clickable label that, once clicked, will reveal the content.
   [hide]Content[/hide]
If you want to customize the label, or have it says something other than "Click to reveal hidden text", you can do something like:
   [hide="Label to display"]Content[/hide]
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.
   [tip]Content[/tip]
If you want to customize the label, instead of saying "Hover for tip", you can do something like:
   [tip="Label to display"]Content[/tip]

I got the message "Too many messages." when trying to send a private message, why?

To prevent PM spam abuse like "asdfghjklkjhgfdsasdfghjklkjhgfdsa", users with less than five forum posts are limited to four private messages within a forty-eight hour period.

How do you tell if someone has blocked private messages?

If you're not sure, try to private message them. It should say you can't. Or go to their user page. It should say so (Private message). Finally, you can check their posts, because generally you can private message about a post.

How do you private message yourself?

If you want to private message yourself to remember something, you have to go to one of your posts, and click the PM button in the top right corner. Then you reach a private message screen where you can backspace the text and write your message.

Posting often makes me a better user, right?

It will depend. Often, it's just the opposite. The quality of your posts matters 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.

I have posted in a forum, but my post count did not increase. Why?

Some forums, including the Test Forum, Mafia, Fun Factory, and other user created forums, do not count toward total posts.

Please do not edit the Wiki just for advertising. I see you, Ultim@te G@mes staff members.

I believe a post needs corrective action. What should I do?

If you believe a post needs moderative action, you may report it by clicking the Z 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.

How do I post images?

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.
  • Go to https://imgur.com/upload
  • Upload your image, and wait for it to complete
  • Hover your cursor over the image
  • Click the 3 dots in the upper right corner
  • Click Get Share Links
  • Find the BBCode option, which should start with "[img]", and click the green Copy Link button
  • Paste the copied text into your forum or blog post.
In general, if you have any online image that you want to post, you can right-click on it, click copy image address, and paste it into AoPS, in between an [img][/img] tags.

How do I become a moderator of a forum?

The creators of user-created forums select moderators in several different ways. Contact the creator(s) of the forum for information.
To see the list of moderators, click the little i icon on the slight-upper-left corner, next to where the name of that forum is.
If you are the creator, and want to know how to make a user a moderator, follow these steps:
  • Click the little i icon on the slight-upper-left corner, next to where the name of that forum is.
  • Below the Permissions section, there should be a list of moderators. Click the pencil button to edit.

Many users often ask and talk about "forum rankings." How do I see it?

Forum rankings are how forums are ranked. There is no confirmation from a site administrator on how these are ranked, but most users suspect that they are ranked on activity.
Here is how to view forum rankings:
  • Go the the community.
  • Scroll down to the section Other Forums and Collections
  • In that section, find the folder Other Forums. The direct link is https://artofproblemsolving.com/community/c9
  • Scroll down the first few rows of forums until you reach a forum called College
  • Every forum after that is user-created and ranked. The first forum after College is the first in rankings, the second one is second, third one is third(user created forums usually) etc.

Blogs

How come I can't create a blog?

In order to be able to create a blog on AoPS, you have to be a member of the community for at least 2 weeks, before creating any sort of blog, forum, or etc.

How do I make my blog look nice?

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.
Try copying CSS of other blogs but remember to give them credit!

Blog Settings

The maximum amount of characters for the Post Comment Text, Comments Text, One Comment Text, and No Comments Text is 40 characters.

Why are usernames a different color?

Blogs use a different stylesheet than the rest of the site and blog owners can customize their blog, including some portions of the feed widget, and therefore usernames show differently in a blog than on the community. Additionally, in the forums, black means a regular user, green means a moderator, red means an administrator, and blue means Site Admin.

Alcumus

How is rating computed?

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.

I am stuck on a problem, and changing the topic does not change the problem.

Alcumus provides review problems to make sure you still recall information learned from the past. These problems cannot be skipped unless you go to an entirely different subject.

Contests

Where can I find past contest questions and solutions?

You can find them in the Contest Collections section.

How do I get problems onto the contest page?

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.

What are the guidelines for posting problems to be added to the contests section?

Refer to the guidelines in this post.

Why are the contest collections missing many contest questions ?

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.

Where are all of the mock contests?

User-generated mock contests are now in its separate subforum, AoPS Mock Contests. Please use that forum for creating, hosting, participating in, or recruiting writers/test solvers for mock contests.

How can I host a mock contest?

See posts on writing a mock contest and Tips for Organizing a Mock Contest.

LaTeX and Asymptote

What is LaTeX, and how do I use it?

$\text{\LaTeX}$ is a typesetting markup language and document preparation system. It is widely used for typesetting expressions containing mathematical formulas. AoPS LaTeX Quick Start Video. See also LaTeX:About.

How can I download LaTeX to use on the forums?

There are actually no downloads necessary; the forums and the wiki renders LaTeX commands between dollar signs.

How can I download LaTeX for personal use?

You can download TeXstudio here or TeXnicCenter here

Where can I find a list of LaTeX commands?

See here.

Where can I test LaTeX commands?

Sandbox or TeXeR. You can also use our Test Forum.

Where can I find examples of Asymptote diagrams and code?

Search this wiki for the <asy> tag or the Forums for the [asy] tag. See also these examples and this article (click on the images to obtain the code). See also this Quick Start Asymptote Video.

How can I draw 3D diagrams?

See Asymptote: 3D graphics.

What is the cse5 package?

See here. The package contains a set of shorthand commands that implement the behavior of usual commands, for example D() for draw() and dot(), and so forth.

What is the olympiad package?

See here. The package contains a set of commands useful for drawing diagrams related to olympiad geometry problems.

I have a question about LaTeX or Asymptote, and it's not answered in the wiki. What should I do?

Go here. This is a forum for $\LaTeX$ and Asymptote. If you have a question, search to see if it's been asked before, and, if not, you can make a new post.

AoPSWiki

How do I sign posts on the discussion forums if I have a question?

Type four tildes (~) and it will sign for you.

Is there a guide for wiki syntax?

See wiki markup, AoPS_Wiki:Tutorial, and Help:Contents.

What do I do if I see a mistake in the wiki?

Click "edit" and correct the error. If it's just a typo, check the "This is a minor edit" box.

What if I need more information because I suspect it's a mistake, but I'm not sure?

Post it on the discussion board! Also, note that if it is about contests, many contests release their questions after the contest, so you can double-check there.

Miscellaneous

Is it possible to join the AoPS Staff?

Yes. Mr. Rusczyk sometimes hires college students to work as interns, graders, and teaching assistants. You must be at least in the second semester of your senior year of high school and you must be at least 18. See the careers page for more information.

What is the minimum age to be an assistant in an Art of Problem Solving class?

You must have graduated from high school, or at least be in the second term of your senior year.

How do I befriend someone on AoPS?

From your My AoPS page, you send out a friend request by typing their username in the corresponding box. You can also go to their account and press the 'add friend' button. They can then choose to accept or decline from their My AoPS page. You can also accept or decline friend requests from your My AoPS page. If you mean to make friends, that takes time and interaction.

What if I miss a class?

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. Keep in mind, though, that whispers (Things the instructors say to you, and only you, to help you understand stuff) won't be shown, and you won't get to ask questions. However, class moves quicker! You can also ask questions on the class message board. Don't worry, though, classroom participation usually isn't weighted heavily.

Is there audio or video in class?

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. Classes taken at the AoPS Academy Virtual Campus will have video. During the COVID-19 crisis, all AoPS Academy classes are running online using the Zoom video conferencing platform. However, there are AoPS videos with audio in some classes, and they can be very helpful, in case the class material doesn't seem easy.

What if I want to drop out of a class?

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.

For my homework, there is supposed to be a green bar but it's orange, why?

The bar turns green if and only if the required writing problems are saved.

I need more time for my homework, how to get it?

There is a "Request Extension" button in the homework tab of your class. This will automatically extend the due date to 1-3 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 2-4 times depending on how many weeks your class is. After, you will need administrator approval.
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.
