Where AMC 8, 10, and 12 Overlap — and Where They Split

Every module below matches the real contest's question count and per-question pacing. Work through the shared foundation first, then branch into each level's own territory — hints and concept notes appear the instant you answer.

Shared Foundation

AMC 8 & 10
Arithmetic, ratios/percents, linear equations, basic geometry, number theory, counting & probability

Core Bridge

AMC 10 & 12
Quadratics & Vieta's, exponents/logs, sequences, coordinate geometry, basic trig

AMC 12 Exclusive

Complex numbers, trig identities, vectors, 3D solids, advanced combinatorics & modular arithmetic

EASY → HARD · WORD PROBLEMS WOVEN THROUGHOUT EACH MODULE
