The exams somewhat overlap, with the medium-hard AMC 10 questions being the same as the medium-easy ones on the AMC 12. Since 2002, two administrations have been scheduled, so as to avoid conflicts with school breaks. Students are eligible to take an A exam and a B exam, and may even take the AMC 10-A and the AMC 12-B, though they may not take both the AMC 10 and AMC 12 from the same date.
