AMC 10 vs AMC 12: Which Should Your Student Take?
The right contest is the one that gives your student the best signal. Sometimes that means protecting accuracy on AMC 10. Sometimes it means letting a stronger student face the fuller AMC 12 range.
For the 2026-27 cycle, the MAA lists AMC 10/12 A on November 5, 2026 and AMC 10/12 B on November 13, 2026.
Key facts
AMC 10 is for eligible students in grade 10 and below and excludes topics like trigonometry, advanced algebra, and advanced geometry.
AMC 12 is for eligible students in grade 12 and below and covers the full high school curriculum except calculus.
MAA policy says students may not take AMC 10 and AMC 12 on the same competition date.
Start with grade and age, then look at the math.
The AMC 10 is designed for students in grade 10 and below. The AMC 12 is designed for students in grade 12 and below. The MAA also sets age limits for each contest.
If your student is only eligible for one contest, the decision is simple. If they are eligible for both, the better question is not which contest sounds more impressive. It is which contest gives the clearest next step.
AMC 12 is broader. AMC 10 is not automatically easier.
AMC 12 includes a wider high school math range, including trigonometry and more advanced algebra and geometry. AMC 10 excludes those advanced topics, but still demands strong problem-solving judgment.
A student who knows more advanced content may still be better served by AMC 10 if they are losing points through speed, reading, or contest strategy. A student who is already accurate and comfortable with advanced high school topics may benefit from AMC 12.
Choose AMC 10 when precision, timing, and contest basics are the main training target.
Consider AMC 12 when the student already has the broader content and needs a higher ceiling.
Use a timed diagnostic set before deciding, not just course transcript history.
A and B dates create options, but not unlimited ones.
The A and B versions happen on different November dates. MAA policy allows eligible students to take an A version and a B version, but not AMC 10 and AMC 12 on the same date.
That means the calendar can support a thoughtful plan. It should not become a reason to overload the student with every possible contest.
Pick the contest that makes review useful. A confusing result wastes more prep time than a humbler, cleaner signal.
