What is the AIME?

The American Invitational Math Exam (AIME) is an invitational exam for top-scoring students from AMC 10 and AMC 12. It is a 15 question, 3-hour examination, each answer is an integer number between 0 to 999. Top scoring participants on the AIME are invited to take the USA Math Olympiads (USAMO) or USA Junior Math Olympiads (USAJMO). Starting in 2022, it is offered in February. AIME is the second exam in a series of competitions that eventually lead all the way to the International Mathematical Olympiad (see Invitational Competitions).
