• Cheating on the MCR

  published by savir 2 days ago.

  Hi all,
  I regret that I must address this matter, however cheating has become very prevalent on the MCR. We have had cases where users use scripts or bots to answer questions, and even users cheating on rated contests. The most recent offense was committed by a participant with the handle "nickname", who engaged in cheating both during the "Challenge for the Weak 1" contest and subsequently fraudulently achieved a 1st place ranking. I would like to remind everyone that such misconduct is dealt with harshly, and penalties include:
  i) being permanently banned from the MCR service
  ii) a public announcement regarding your misconduct
  iii) repeated offences may result in our admins contacting you or your institution
  Please be reminded that the MCR operates as a not-for-profit mathematics community. Disregarding its principles is equivalent to showing disregard for the value of free education. Additionally, you are diminishing the experience of your peers who are diligently working to achieve a high ranking.

• Using the MCR for a Club or Organization

  published by savir 2024-07-09.

  We've recently received several requests from tutors and organizations for an instance or "clone" of the MCR for their business. While our platform is not open source (and thus we can't provide traditional clones), we have two solutions for this.
  - You can request for an MCR organization to be created for your club or company at just \$10/month (\$100/year). You will be able to host your own problems on our database, and they will only be visible to your students. You can also create special examinations and homework that only your students can see.
  - You can request for an API key for \$5/month (\$50/year) which allows you to use problems from our collection and check answers in real-time. Programming experience is required, of course, to create a private platform based on this.
  
  Please email mathcontestrepository@gmail.com or ping @savir on any MCR community to get started with one of these options! (More API information will be added to this announcement as it rolls out)

• MCR Mock PCF Contests

  published by savir, herosoulz, yujhtheyujh, snowfall, taras 2024-02-25.

  Hi everyone,
  We're excited to announce a mock PCF contest on the MCR. The contest opens around noon on Monday, February 26 and will be available until the evening of Thursday, February 29. The actual Fermat contest will be on Wednesday, February 28.
  Once the contest opens, it will be available on this page.
  This contest was tested and set by savir, herosoulz, yujhtheyujh, snowfall, taras, and some other anonymous users. As such, the round will not be rated for these users.
  The mock round will not emulate the contest format, however it will emulate the difficulty level(s).
  More information will be available when the contest opens on the contest page! Good luck everyone!

This platform allows you to access, submit answers to, and view solutions for past math contests, olympiads, and curriculum problems. We also host some of our own contests once in a while to prepare you for the real deal! While this site is intended for high school and/or undergrad students, others may also find it useful for preparing!
