In addition, high scorers on the AMC 10 and AMC 12 qualify to take the next round of competitions, the 3-hour long American Invitational Mathematics Examination (AIME), typically held in March or April. Any student who scores in the top 1% on the AMC 10 (or 2.5% as of 2011), scores in the top 5% on the AMC 12, scores at least 100 points on the AMC 12, or scores at least 120 on the AMC 10 is invited to take the AIME. The answer to each of the 15 questions on the AIME is an integer between 0 and 999 inclusive, so while it is technically a multiple-choice test, it is not one in practice.
