Hey guys! I barely passed my AMC 12A this year with a 99 score and I’m about to take AIME. I was just curious as to what the cutoff score for USAMO is, because some websites mention that the cutoff score is a cumulative score of the AMC and AIME score, while others just give a set amount of questions that need to be correct. Does anyone know if the USAMO cutoff score is calculated cumulatively or just through a minimum amount of correct AIME questions? Thanks!
In recent years, they use your index, which is defined as AMC score + 10*AIME score, for a max. index of 300. In past years, USAMO cutoff from the AMC 10 was usually determined by a certain AIME score (such as 7+, 9+).
USAMO cutoff indices are usually around 200-210, although I took the 2011 AIME I, which had an awfully low cutoff of ~188 if I remember correctly.
