AMC 8 – The Starting Point for Young Problem Solvers
The AMC 8 is a 25-question, 40-minute mathematics competition designed for students in Grade 8 and below. It is an excellent introduction to competition mathematics: the underlying ideas are accessible to middle-school students, while the problems require significantly more reasoning than straightforward curriculum exercises.
According to the MAA, content can include:
- Counting and probability
- Estimation
- Proportional reasoning
- Elementary geometry and the Pythagorean theorem
- Spatial visualisation
- Interpretation of graphs and tables
- Beginning algebra: linear functions, quadratic functions and coordinate geometry
Why AMC 8 questions feel different. A normal classroom question effectively says: "Here is the method. Apply it." A competition problem makes the student decide: "What mathematical idea should I use in the first place?"
The challenge isn't necessarily advanced content. It is recognising the hidden structure of the problem, and combining fractions with logic, geometry with algebra, or counting with pattern recognition. That is why completing a Grade 8 curriculum doesn't automatically mean a student is ready to score highly on AMC 8.
AMC 10 – The Next Step
The AMC 10 is a 25-question, 75-minute multiple-choice competition for students in Grade 10 and below. It includes elementary algebra, geometry, area and volume, elementary number theory and elementary probability. The MAA excludes advanced topics such as trigonometry, advanced algebra and advanced geometry from the AMC 10 syllabus.
That should not be confused with the competition being easy. The later AMC 10 questions can require considerable ingenuity even when the underlying mathematics is relatively elementary.
AMC 10A vs AMC 10B. These are two versions of the AMC 10 administered on different dates. They are not an "easy" and a "hard" version. The MAA allows eligible students to take both the A and B competitions, although a student cannot take AMC 10 and AMC 12 on the same competition day.
For serious competition students, taking both versions can provide two competition experiences in the same cycle, where local and international arrangements allow it.
AMC 12 – Advanced High-School Problem Solving
AMC 12 is also a 25-question, 75-minute multiple-choice competition, designed for students in Grade 12 and below. It covers a broader range of high-school mathematics than AMC 10, including advanced algebra, advanced geometry and trigonometry. Calculus is excluded.
Like AMC 10, AMC 12 is offered in A and B versions on different competition dates.
What Happens After AMC 10 or AMC 12? – AIME
Strong performers on the AMC 10 and AMC 12 can be invited to take the American Invitational Mathematics Examination (AIME). AIME represents a substantial jump in difficulty: the MAA also notes that AIME problems are more difficult than AMC 10 and AMC 12 problems.
For the 2027 competition cycle, the MAA describes AIME as a 15-question examination, with answers given as integers from 0 to 999, administered in two 90-minute parts. There are no multiple-choice options to help students: they must solve the problem and determine the answer.
For the 2027 cycle, the MAA has announced guaranteed AIME qualification for eligible students scoring 100 or above on AMC 10 or 85 or above on AMC 12, alongside the applicable qualification policies. Qualification policies can change from year to year, so check current MAA information for your competition cycle.
