The AIME (American Invitational Mathematics Examination) is an intermediate examination between the AMC 10 or AMC 12 and the USAMO. All students who took the AMC 12 and achieved a score of 100 or more out of a possible 150 or were in the top 5% are invited to take the AIME. All students who took the AMC 10 and had a score of 120 or more out of a possible 150, or were in the top 2.5% also qualify for the AIME.

The Mathematical Association of America wants to increase interest in mathematics and to develop problem solving through a friendly and fun competition. The purpose of the AMC 8 is to demonstrate the broad range of topics available for the junior high school mathematics curriculum. The AMC 12 covers the high school mathematics curriculum, excluding calculus. The AMC 10 covers subject matter normally associated with grades 9 and 10. Site includes past AMC Archives.

Math Contests contains the actual math contests given to students participating in Math League Contests, Grades 4, 5, and 6, School Years 1979-1980 through 2010-2011, and Grades 7, 8, and Algebra Course 1, School Years 1996-1997 through 2010-2011. The contests are designed to build student interest and confidence in mathematics.

The USAMO provides a means of identifying and encouraging the most creative secondary mathematics students in the country. It serves to indicate the talent of those who may become leaders in the mathematical sciences of the next generation. The USAMO is part of a worldwide system of national mathematics competitions. Sponsored by MAA American Mathematics Competitions.
