The AMC 12 is a mathematics competition designed for high school students in the United States. It is part of the American Mathematics Competitions series and focuses on problem-solving skills in algebra, geometry, and basic number theory. The exam consists of 25 multiple-choice questions, and students have 75 minutes to complete it. The AMC 12 is typically held annually in February and serves as a qualifying round for the AIME (American Invitational Mathematics Examination). High-performing students may advance to further competitions, including the USA(J)MO (USA Junior Mathematical Olympiad) and the USAMO (USA Mathematical Olympiad).
