AMC 12B 2026 — US registered sites

AMC 12B is the Nov 13, 2026 offering in the 2026–2027 MAA mathematical olympiad pathway. It contains 25 multiple-choice problems in high-school mathematics, including advanced algebra, geometry and trigonometry; calculus is excluded. A competition manager administers paper or digital answers in person at the registered venue; digital delivery does not allow home/remote proctoring. This entry covers US venues, which students select through their school or another registered institution. Success can lead to AIME and later USAMO/USAJMO under those stages’ separate eligibility rules; it does not guarantee selection.
