Cheating on the MCR
published by savir 2024-09-12.
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)
You're not authenticated at the moment. Let's get you signed up or logged in.
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!
Want to track how much you've progressed? Our smart skill level indicator tells you exactly how good you are at math right now.
The Math Contest Repository grades solutions based on MCRX 3.4, the world's most advanced online contest grading technology. We use algorithms that feature support for both offline grading and adaptive index grading.
