AMC 8 The AMC 8 is a 25 multiple-choice question, 40-minute competition designed for middle schoolers. High scores on the AMC 10 or 12 can qualify the participant for the American Invitational Mathematics Examination (AIME). Since 2002, two AMC 10/12's are offered annually (known as the AMC 10/12A and AMC 10/12B) Students are eligible to compete in an A competition and a B competition, (e.g., the AMC 10A and the AMC 12B), though they may not take both the AMC 10 and AMC 12 from the same date.
