AMC 10 and AMC 12 (American Mathematics Competitions)
The standard way to show quantitative rigour on an application to an American university, and the qualifying route to the AIME and the olympiad path beyond it. Twenty-five questions in 75 minutes on advanced algebra, geometry, number theory and combinatorics. For 2026/27 the A versions run November 5, 2026 and the B versions November 13, 2026. October 15, 2026 is the final registration deadline for a school that has never hosted before, so if no school near you offers it, ask a math teacher to sign up as a competition manager well ahead of that.
