AIME Qualification Changes
Starting in 2011, the qualification parameters slightly relaxed for the American Invitational Mathematics Examination (AIME). For students taking the 2013 AMC 10 contests, students in the top 2.5% of all scorers or scorers or with at least 120 points (whichever is more inclusive) to the AIME. This differs from the values of 1% (or 120 points) which have been in effect since 2004. For students taking the 2013 AMC 12, students in the top 5% of all scorers or scorers with at least 100 points to the AIME. These AMC 12 qualification values remain at the same level they have been since 2000.

For AMC 10 takers, the cutoff core to qualify for AIME was 115.5 in 2012. It is 108.0 in 2013 due to a little harder problems.
