The AIME is the second of two tests used to determine qualification for the United States Mathematical Olympiad (USAMO), the first being the AMC.
Concepts typically covered in the competition include topics in elementary algebra, geometry, trigonometry, as well as number theory, probability, and combinatorics.
Many of these concepts are not directly covered in typical high school mathematics courses; thus, participants often turn to supplementary resources to prepare for the competition.
[4] Hence, there will be a total of 8 published USAMO and USAJMO qualification cutoffs per year, and a student can have up to 2 USAMO/USAJMO indices (via participating in both AMC contests).
However, in 1994, an unprecedented 99 students achieved perfect scores on the AHSME, causing delays in result distribution.
The second date serves as an alternate test for students who miss the first due to conflicts such as spring break or illness.
The alternate competition, commonly called the "AIME2" or "AIME-II," is usually given exactly two weeks after the first test, on a Tuesday in early April.
Instead, qualifying students were able to take the American Online Invitational Mathematics Examination, which contained the problems that were originally going to be on the AIME II.
