i Recruiting (Problem Writers & Test-solvers)
LauraZed   983
N May 8, 2025 by ItzsleepyXD
Do you need help writing a mock contest? Or just want some people to test-solve your mock? Post in this thread!

Make sure you clearly state how others should get in touch with you if they're interested in helping you write problems or test-solving. To keep this thread readable, I'd recommend having them contact you through PM or sign up on a form outside of this thread (but on the flip side, I would strongly advise against giving out your email address or any other personal contact information in this thread – and remember that you can't require people to give any personal information either, per the ToS.)

i Tips for Organizing a Mock Contest
Mudkipswims42   59
N Apr 2, 2025 by PhoenixMathClub
Hello peoples of AoPS! I have decided that for my 7218th post I will help aspiring young problem writers with the organization of their contests. (Note I did not say writing a contest, for that see here)

Well lets get on to it! Here are a few pointers:
[list]1. Write all the problems before making the "advertising" contest post.[/list]

If you need help on making the problems or with proofreading and test-solving, what I would recommend is making a post only asking for help and let them volunteer through PM. Once you have enough helpers, you can always just say in the thread that you have enough; no need for a signup list :). It is better to have two different threads which serve their purpose then one which is unprepared on either side.
[list]2. Make a private forum to create and propose problems in.[/list]

I think a really good way to organize your writing is to make a private forum in which you make the problems. This is helpful because you can individually propose a problem in each thread, and all discussion for that problem (difficulty, placement, quality, etc) can stay in that thread. This keeps everything very organized (you can make an outline thread an announcement, so its clear which problems you are deciding to put on the test). Another reason its helpful, is because you can include the people who are proofreaders or difficulty gauges into the forum, and they can work with you as you go. In order to increase activity, I would recommend telling the users involved to bookmark the private forum, that way they can see if there is a new development.

[list]3. Have a clear idea of how people will submit.[/list]

This is a crucial part in the organization of your contest. You should be clear about it in your contest thread, and clear about it in posts afterward. The two general submission processes are via PM (Private Message), or through a Google form. For a PM, make sure you specify who to add to the PM, and in what format they should submit their answers. Google forms is probably the best way of submitting, as you don't get a cluttered PM box where you might miss a submission or two. On the flip side, you can and may receive troll submissions, but you can delete them pretty easily. There are some general things you want to put on the form: [list]Name, (aka the AoPS username)

*Problem answers* (you can do this problem by problem, and if it's an AMC I would recommend giving the answer choice options)

Comments on the test (You can split this up however you want)

Thanks for submitting (^_^)[/list]
If you don't now how to make a google form and spreadsheet, either ask for someone who does (on the help thread) or learn! (learning how to do spreadsheets is a very helpful)

[list]4. Don't forget post-test management![/list]

It's always a bummer when someone takes the test but the host does not remember to officially end it and open discussion. When posting results be sure to include only those who want to be included in the results. The best way to find this out is asking users through PM when you send them their score report. LaTeX tables are fancy and look sophisticated when posting results, but I recognize that most people cannot make these (I for example can't :P). It's fine to use the old fashioned hidden text to announce the top few scorers and other honorable mentions. If you are a stats guy, be sure to show problem statistics in an organized way; aka don't say random statistics sporadically in your post but instead show a few related stats like most missed and most correct. Remember to thank everyone for their submissions!

[list]5. Create a forum for problem discussion, or post a few questions in main forum based on difficulty.[/list]

This is always a tough question when opening problem discussion: do I create a separate forum or do I post in the main fora. The answer is: it depends. If your contest has many problems, then you don't want to post all of them and end up flooding one of the main fora (Middle School Math, High School Math, or High School Olympiads) with a lot of posts. In that case you should either create a new forum to discuss all problems, or only post the last few on your test, I would recommend the former, as all problems can be discussed :). If your contest is an Olympiad, or something with not too many questions, then by all means post the questions in the main forums! But don't forget: post each question in a forum where its difficulty is accurate. For example, don't post problems from an AMC12 in Middle School Math, or problems from an AMC8 in High School Olympiads! If you have some problems that are Middle School Level, and some that are High School level on your test, then post them in different forums; you can always provide links to each problem in your contest thread. For example, when my group released problems from the All Algebra Assessment we posted some questions in Middle School Math, some in High School Math, and some in High School Olympiads.

When people are discussing be sure to wait to see other solutions, before posting your official ones. Waiting a few days before posting a solution is perfectly fine. You want your problem to be discussed don't you! If your official solution is the same as some other user's then there is no need to post it, as it's just a repeat :P.


Lastly, to help you guys organize your contest post, I have made a sort of template for it :-D! You don't have to follow it exactly, just be sure you include these things in your post:

*Greeting and Introduction*

*Present your contest with your other fellow problem writers* (Example "AceTheIMO, adriel, and I bring you (bigish text)Mudkips Mock!(bigish text))

*Quickly describe contest, including rules*

*Give credit to testsolvers, proofreaders, and other help*

*signups format* (this may or may not be necessary, considering you could just ask the people to submit and that would count as a participation)

*submissions format* (put Google form here if you made one)

*Submission deadline*

*leaderboard* (optional)

*TEST LINK* (if you want to title it use the[code]Title[/code] code or just attach the doc to your post)

*~Sign off*

lastly don't necessarily feel obligated to follow these rules too strictly (weird rule :P)

Well I hope this was helpful, and good luck on your mock! :)

Thanks for reading,

i Mock Contests Forum Guidelines
LauraZed   37
N Oct 11, 2024 by jb2015007
First, if you...
[list]
[*]...are interested in writing a mock contest yourself, check out this guide for writing a mock contest, and
this post for additional tips on how to organize a mock contest.
[*]...want to find great past mock contests, follow the links in the Mock Contests section of this AoPS Wiki page.
[*]...need other people to help you finish writing a mock contest, or want to help out someone else finish their mock contest, check out this thread.
[/list]
Now that we're past all that, here are the guidelines for how this forum will work:
[list=1]
[*]Don't advertise unfinished mock contests. If your mock contest isn't finished yet and you want to recruit other users to help you finish it or test-solve it, post in this thread instead.

[*]Make sure there's a clear way to participate when you make a post announcing your contest! In other words, if you want to send the contest out to people, let them know how to sign up to receive the contest. On the other hand, if you just include a link to the contest in your announcement, there's no need to ask people to sign up – but make sure to tell them how to submit their answers.

[*]Discussion of each mock contest can take place either in the announcement thread, in a new thread in this forum, or in a discussion forum for the contest. If you want to, it's fine to hold a discussion of the contest in the same thread you announced it. Alternatively, you could start a new thread for discussion once the mock contest is over (in this case, I'd recommend sending in a report on the announcement thread to request that it be locked – then you won't end up with people discussing the test in two places). Finally, you could create a new forum just for discussion of your mock contest if you want people to discuss each problem individually – or you could post a few of your favorite problems in the general math forums.

[*]And, of course, follow general AoPS Community rules, like the AoPS Terms of Service.
[/list]
Have fun creating and solving problems! :laugh:

i Hi! I'm Interested in Writing a Mock Contest!
djmathman   209
N Jan 16, 2023 by MrThinker
Well, that's great news! Art of Problem Solving has a long and storied tradition of mock competitions. It's great to see that you're interested in continuing this tradition! However, know that because the history of mock competitions goes back so long, there is a great deal of honour and responsibility placed onto the young ones who choose to embark on this journey.

I know what you're thinking: "How can I make sure I use this honor to my advantage?" Great question! It all starts with the idea....
[list]
[*]Decide what type of contest you want to write. This may seem like a simple step, but it goes a long way into deciding how the fate of the contest will play out. Choose whether you want to write an AMC8/10/12, an AIME, an USAMO, or something completely new and unexpected. By doing this now, you'll be able to gauge the difficulty of the questions and can set up your mind appropriately. (That being said, you don't have to necessarily stick to your original idea! However, knowing what you're going to write ahead of time is beneficial in terms of organization.)
[*]Start writing problems! Usually a .tex file will suffice. If you're collaborating with others, a Google Doc (with a $\LaTeX$ add-on such as Auto-Latex Equations enabled) or ShareLaTeX/Overleaf file works best. Keep your questions organized in some sort of shortlist, possibly sorted by category. Don't start organizing questions into the actual contest just yet - it's too early to start pigeonholing yourself! Just start exploring ideas and see what comes. This is probably the time when you'll write the most number of problems per day.
[*]Don't post about the contest on AoPS yet! As is often said... wait darn, I forgot the adage that's quoted here... oops
[/list]

"Wait", but you say, "writing problems is hard D:".

Well, I agree, young one! Nobody ever said administering a contest would be easy. (Well, almost no one.) How exactly does one go over the hurdle of writing problems?

[list]
[*]Write problems backwards. This is one of the standard problem-writing techniques. Essentially, it boils down to "here's an interesting idea - how can I mold it into a problem"?
As an example, consider this problem from NIMO Contest 15. Over the summer, I was interested in writing a problem that revolved around the factorization $n^4+n^2+1=(n^2+n+1)(n^2-n+1)$. After playing around a bit, I realized that the second factor could be written as $(n-1)^2+(n-1)+1$, meaning that I essentially had a functional equation of the form $f(n^2)=f(n)f(n-1)$. This then led me to try writing a telescoping problem. Trying things involving partial fractions didn't work, but working with products did yield something cool. I then realized that what I had created could be molded into a nice-looking form, and after a few more adjustments I came up with the finished product.
[*]Also write problems forwards. This is another one of the standard problem writing techniques. This technique in simplistic form is "here's an interesting idea - what results can I get from it that can turn it into problems"? It seems very similar to the previous bullet point, but in fact it's quite different: here, you have no idea what the end product is going to involve.
As a (very) extreme example, consider this problem from NIMO Contest 21. This problem actually started development two years ago, when I was inspired by an AMSP Team Round question to look at constructing triangles with a given inradius and circumradius. I made no progress on this for a long time, but in February of this year, I realized that the formula $OI^2=R(R-2r)$ essentially killed the problem I had in mind. With this breakthrough, I hid the true meaning of the question and eventually came up with this.
Around late July 2015, I gave this problem to Evan in a set of problems to check; his interpreted the problem in a completely different manner, responded with "the key observation is <something completely different from what I had intended>" and rephrased the problem in terms of perimeters. This new version I considered nice enough to end up submitting to the NIMO database.
However, the problem still wasn't finished evolving! When putting the problem onto Contest 21, I was unsure of the difficulty (and the configuration, but that's a different story) because it seemed like the problem was too focused around noticing one trick. I played around with the configuration a bit more and found that knowing the distance between the incenters and those two perimeters allowed one to uniquely determine the trapezoid! With this discovery in mind, the problem finally became the finished product put on the contest.

... what was I saying again? Oh right, problems!
[*]Don't artificially inflate the difficulty of problems by adding unnecessary components. This is a common pitfall for beginning problem writers (and experienced ones, too!) As a rule of thumb, the amount of work needed to compute the answer to a question should be at most the amount of work needed to find the main idea, unless the computation is part of the main idea itself. For instance, a problem asking to find the value of $1+7+7^2+\cdots+7^{10}$ is a bad problem because although the idea of geometric sums is easy, computing $7^{11}$ is not.
[*]Using well-known problems as inspiration is okay; using them for the finished product is less okay. Long story short, don't try to put problems that 90% of the participants will have seen before. Of course, if you're running a deadline and the problem is really really obscure, odds are high that nobody will notice, but leaning on this is bad practice, especially in the long run.
[*]Don't overestimate the difficulty of the early problems! This is an extremely common mistake that occurs in user-generated contests. Remember, the AMC's (for example) are meant to be accessible, and as such the early problems are not supposed to be hard. If you're having trouble determining whether a problem is appropriate for the beginning, look at early problems from previous contests and compare them! (Or better yet, have a friend compare them!)
[*]Try to be creative! The problems that are most remembered are the ones that take familiar concepts and twist them in new and interesting ways. This is one of the reasons why Mandelbrot problems are so highly revered - they may not be the hardest problems ever, but you sure can't accuse them for lack of originality! Take care into writing your problems - after all, the contest is your work, and how quality the finished product is can affect the way people perceive you for future projects. (This is easier said than done. Often times, the cure for badproblemaphobia is simple: practice writing more problems! Question-creation is just as much of an art form as mathematics itself.)[/list]

“Okay”, you say. “I have all the problems written, and I’ve made sure all the answers are correct. Now what?”
Well, it’s time to release to the world!
[list]
[*]Advertise your product! Be proud of what you’ve written. But don’t release the test yet! Give your contest time to spread through the community.
[*]Make clear the method in which you have participants sign up. Also, make sure it’s organized. Recently, there have been some mock contests which have had flawed methods of signup and suffered because of it. Think through how you want to administer the contest before you announce it to the AoPS-verse. (These are all important things to ensure a successful mock!)
[*]Recruit testsolvers! It’s easy to look over potentially fatal flaws if you’re the only one who looks over the test before it’s released. Get a few friends to help look it over! Some contests prefer to do this through sign-ups analogous to the normal ones; others just prefer to PM their prospective targets directly. Either way, get a bunch of people to agree, because not everyone will ultimately have time to follow up. (I’m not saying this in an evil and bitter way – it’s just human nature!)
[*]Prepare for the big day! It’s almost here!
[/list]

All right, the lights are on, the stage is set, and the cameras are ready. Action!
[list]
[*]Make the location of your test clear. Once again, be proud of your work!
[*]Take errors with grace. Sometimes, even with test-solvers, mistakes happen! Don’t let them pull you down too much. Make changes to the actual test, notify users (whether in-thread or through PM) of the changes, and adjust scores accordingly.
[*]Ask for feedback! Problem writers are always looking for ways to improve, so give honest criticism! I usually like to achieve this through a few questions at the end of a Google Form. This usually generates healthy participation, although other methods can probably work just as well.
[*]Watch as scores pour in! Whoo!
[/list]

And that’s all! If you have any ques…

“… that’s a lot of work. Are there any examples I can use to convince myself something like this is even possible?”
[list]
[*]All official AMC/AIME contests. These are contests written by people, too! More importantly, many of the individuals who contribute problems to these contests are not professional problem writers – they’re volunteers, willing to put in time to write interesting questions for the world to see.

But I imagine this was not the answer you were looking for? Fine….
[*]Mildorf’s Mock AIMEs. These five AIMEs are often referred to as the gold standards for mock contests. These are really hard (especially for pre-2005 times), and can give you a sense of the potential of what a mock contest can look like.
[*]djmathman’s Mock AMC10/12. Okay, maybe I’m a bit biased here, but I can afford to be a little biased, right? In any case, this AMC was met with generally positive criticism, so there’s that. The AMC10 is probably similar if not a bit easier than usual, while the AMC12 is much easier than usual. (This was the result of announcing the contest prematurely!)
[*]The 2015 Mock AIME I. “Okay seriously man, what’s up with all the bias?” Eh, I still think this is an objectively good example of what a mock AIME should look like, even if the difficulty curve is a bit wonky. (This was originally designed to be a Mock Mandelbrot competition, after all!)
[*]The 2015 Mock AIME II (henrikjb). I haven’t been able to look at all the problems in detail, but I can say that the ones I have looked at are of high quality! Another example of the potential a mock contest can deliver.
[*]Many other examples! These are just the contests I remember. If there’s a good example that I’ve overlooked, feel free to link to it in the comments!
[/list]

“I’ll check those out, thanks!”

Any last questions, young fellow?

“I’m still not sure if this thing is right for me. Can you provide some words of encouragement?”
[list]
[*]Even though AoPS can be a divisive community at times, just remember that we’re all here to support you! Writing contests is hard. Nobody’s gonna give you a hard time for a contest you genuinely put thought and effort into! Just remember: as budding mathematicians, we’re constantly looking for good problems to chow down on; as long as that goal is accomplished, the contest was a success. We’re rooting for you!
[/list]
“Yay! Thanks for all the advice, Mr. Omniscient Voice! Time to start writing problems!”

77 AMC 10, 41 AMC 12, and Other Mocks Compiled in Google Drive Folder
zhaohm   10
N 3 hours ago by mpcnotnpc
I always had the dream of having an unlimited amount of high quality and easily accessible AMC mock tests to practice. However, the AoPS Wiki's Mock Contests page takes time to navigate, and there isn't a lot of actual past AMC tests to practice. Therefore, I came to spend 37 hours compiling a folder of the problem (and if available, solution) files of most mock AMC 10/12 tests and some mock AIME, USA(J)MO, etc. tests mentioned in the AoPS Wiki. The folder can be accessed here in google drive.

The AIME, USA(J)MO, and other mocks are not as completely compiled as the AMC 10/12 mocks since although their original problem and solution files may not have been compiled, I realized after working for 10 hours that the user parmenides51 already created compilations of their problem descriptions here in the AoPS Contest Collections page.

Feel free to PM me or post in this topic if you have any comments or suggestions.

Enjoy!

Theory Notes: I will share helpful theory and insights relevant to the problem set, giving you the tools you need to approach the problems.
Submission Opportunity: You can work on the problems and submit your solutions. I’ll review your work and provide feedback.
End of the Week: Solutions Post: I’ll release detailed solutions to all problems from the problem set.
Leaderboard: For those interested, we can maintain a table tracking participants who solve the most problems during the week.

Cycle Finale – Mock Contest
At the end of each 4-week cycle, we’ll host a Mock Contest featuring 4 problems (one from each topic). This is a great chance to simulate the competition environment and test your skills in a timed setting. I will review and provide feedback on your contest submissions.

Starting date: June 2

How to participate? Just write /signup under this post.

I believe these workshops will provide a comprehensive, engaging, and collaborative way to tackle Math Olympiad problems. I'm looking forward to seeing your creativity and problem-solving prowess!

[center]Thanks to peace09, ghu_who, and ChaitraliKA for testsolving and providing invaluable feedback! :D

All of the problem writers have extensive experience with math competitions and MATHCOUNTS, with 3 of our problem writers qualifying for MATHCOUNTS nationals, 4 AIME qualifers, and with many achieving scores of over 130 on the AMCs. Furthermore, our problem writers have led 4 contests that have had over 1,150 participants combined. In addition, this series have been in development for nearly two years, during which hundreds of problems were produced, testsolved, and carefully evaluated to ensure you the best testing experience possible.

Please note that everything listed below is subject to change, and will become more specific as details are finallized.

$\begin{tabular}{|c|c|c|} \hline
\textbf{Competition} & \textbf{Release} & \textbf{Deadline} \\ \hline
School & December 14 & February 1st \\ \hline
Chapter & January 11 & March 14th \\ \hline
State & March 6 & Mid April \\ \hline
National & May 10th & Mid June \\ \hline
\end{tabular}$

The deadline is for prize elligibility, but you can still take it even if the deadline has passed for practice.

The tests will be released through MathDash. You can take it whenever you wish, but you must take it before the deadline to be elligible for prizes. As soon as you finish, you will be able to access solutions immediately. Please make sure that you use the same MathDash account throughout the competition!

[rule]
How do I sign up?
There isn't actually any need to sign up! However, we recommend signing up in the main thread to gauge interest and to promote the threads visibility for more people to see. :)

To sign up, quote the message of the most recent person who has signed up, put your name in the hide tag, and increment the number on the hide tag by one. After that, remove the quote tags to make sure that it is brand new for the next person that signs up. However, if you are unfamiliar with this method, simply typing /signup is okay; someone will sign up for you. If you wish, you can start off sign-ups by copy and pasting this: Signups(0)
[rule]
Will there be prizes?
Indeed! MathDash has generously agreed to give cash prizes to top performers, and we are trying to get sponsors to add to a potential prize pool as well. This is all subject to change, but we are planning to have the prizes increasing from school to nationals, for a total prize pool of around 500 dollars.
[rule]
How will team rounds work?
On MathDash, it's actually to do team rounds without meeting in person, so teams aren't limited by geographic barriers! To register a team on MathDash, have a designated captain create a team. Then, he'll recieve a code, which the rest of the team can fill in to join the captain's team.
[rule]
Will there be a countdown round?
Not decided yet.
[rule]
Message about cheating:
This goes without saying, but please don't cheat. Above all, we want to foster a supportive and welcoming environment, built on trust, where math enthusiasts of all skill levels can thrive. Cheating undermines all of that; by cheating, you are depriving yourself of an opportunity to develop your math skill and learn from mistakes. Math is about struggle, and taking the easy way out goes against these core ideals. On the other hand, acting honestly builds character and a sense of genuine achievement that lasts for a lifetime.

Additionally, MathDash has implemented anti-cheating methods that make potential cheating extremely difficult, and we will deal with any potential suspicious activity on a case-by-case basis. However, if you behave honestly, you won't need to worry about any of that. :)
[rule]
We sincerely hope you enjoy taking part of this competition as much as we did making it, and wish you all best of luck in this years contest series!

Welcome to the first ever MAMC (lame name, it stands for Mock AMC)! This time, the MAMC committee (evt917, MathLoverYeah, and PatTheKing806), has released another mock: The second MAMC 8 (obviously a mock AMC 8).

evt917 and the MAMC committee will also create AMC 10 and possibly 12 mocks in the future (not until very soon though).

Type \signup to signup! Note that you have one week time to finish and give your answers to me once you signup. The signup deadline is all the way until three days before the AMC 8 (you can take the test after the deadline, but evt917 will not grade them and will not put you on the leaderboard). However, the solutions will be released in mid-January. Please do not look at the answers (unless you already took the test)!!! Please don't post your scores unless you signup! :D

Note that there wouldn't be a signup list because evt917 is too lazy to do it.

Wait! I don't want to be recorded into the leaderboard!

What if I find something wrong in the answer key?

How about errors other than the answer key?

What audience is this test intended for?

Can I take this multiple times?

One of my questions isn't answered here!

Thank you for taking it! I hope you have a fun time (and remember not to cheat!) :)

2024 MATHCOUNTS Nationals alumni from all across the nation have come together to administer the first-ever ELMOCOUNTS Competition, a mock written by the 2024 Nationals alumni given to the 2025 Nationals participants. By providing the next generation of mathletes with free, high quality practice, we're here to boast how strong of an alumni community MATHCOUNTS has, as well as foster interest in the beautiful art that is problem writing!

The tests and their corresponding submissions forms will be released here, on this thread, on Monday, April 21, 2025. The deadline is May 10, 2025. Tests can be administered asynchronously at your home or school, and your answers should be submitted to the corresponding submission form. If you include your AoPS username in your submission, you will be granted access to the private discussion forum on AoPS, where you can discuss the tests even before the deadline.

[RELEASED] Mock State MATHCOUNTS (an OMO Team Project)

The phat bohan carries 3 n00bs OMO Team present to you a [center]MOCK STATE MATHCOUNTS[/center]

Originally, mathleticguyyy and I started creating this around the time of our chapter contests, in the hope that we'd have a beneficial resource for you guys to practice for your State competitions. Then quarantine came, so we didn't have as much pressure to create it so quickly, and we spent more time trying to make this test the best quality possible. The Online Math Open came around, and we got solver1104 and I-_-I on board.

Of course, you guys are sad that the MATHCOUNTS season was cancelled. 8th graders, you can use this test for REVENGE for your missing National qualifications. Anyone else can take this just for practice, of course!
-----
You may sign up, though it's not necessary.

To submit, shoot me (Mathscienceclass), mathleticguyyy, or I-_-I (all capital "i"s) a Private Message. There's nothing special here, just submit the answers in a way that we can read them! Note that if you edit the initial message in which you sent the answers, we reserve the right to disqualify you.

There is no set deadline yet, but if we wish to end this, we will announce the date ahead of time. Once over, the solutions will be released here. All discussion should only happen in the discussion forum, which you obtain access to after submitting. It is linked here!
