This mock exactly follows the real AMC 12 structure: 25 multiple-choice questions in 75 minutes, five answer choices per question, difficulty rising from Q1 to Q25.
Real AMC 12 scoring rewards restraint: +6 for a correct answer, 0 for wrong, +1.5 for leaving a question blank. Guessing blindly is usually a losing strategy — this tool tracks your live score the same way.

This is an AMC 12–format practice tool designed as USAMO-pipeline preparation — the actual USAMO is a proof-based exam and is not multiple choice.
