Hello fellow brilliant members.
I am 99.9% sure that a classmate of mine cheated on a math olympiad contest (the USA Mathematical Talent Search/USAMTS) because of several reasons. I'll save you the details, but he scores low (average 3) out of 6 at mathletes meets (he's not on the A-team). And, he has never qualified for the AIME (of the people who didn't qualify, he wasn't in the top 3. The top 3 scorers were in the high 80's range).
Yet somehow he managed to submit 15 flawless proofs on much harder problems. Me and my fellow mathletes and classmates (along with the Calculus teacher) are very dubious of his achievements.
Do you guys have any suggestions on how to deal with abominations as this? Is it best to just leave it alone? If not, how can I and how should I report it?
Thanks for reading. I hope this fits the submitting guidelines as I think the brilliant community will be good at answering this question.
