AMC 8 in 2025

The AMC 8 took place earlier this year, during the testing window from January 21 to January 27. This contest is designed for students in grade 8 or below and serves as an introduction to problem‑solving and competition‑style math.

It included 25 multiple‑choice questions to be completed in 40 minutes. The questions focused on topics like pre‑algebra, basic geometry, number theory, and logic. Calculators were not allowed.

Each correct answer earned one point. Incorrect or blank answers earned zero, and the maximum score was 25. Top scorers were recognized on the Honor Roll and Distinguished Honor Roll. Students in sixth grade or below who scored 15 or higher received a Certificate of Achievement.

If you missed this year's AMC 8, don't worry. It returns every January, and practicing early with past tests is a great way to get ready.

AMC 10 and AMC 12 in 2025

Looking ahead, the AMC 10 and AMC 12 are scheduled for this fall. These contests are open to students in grade 10 or below (AMC 10) and grade 12 or below (AMC 12). They are more advanced than the AMC 8 and serve as the gateway to the AIME and eventually the USA Mathematical Olympiad.

Each test will be offered on two different dates:

• AMC 10A and AMC 12A: November 5, 2025
• AMC 10B and AMC 12B: November 13, 2025

You can take one version or both, but not both versions of the same level. For example, you can take AMC 10A and AMC 12B, but not AMC 10A and AMC 10B.

The format is the same for both AMC 10 and AMC 12. Each test has 25 multiple‑choice questions and a 75‑minute time limit. Calculators are not allowed. The AMC 10 includes topics through Algebra II, while the AMC 12 also covers precalculus.

Scoring works like this: six points are awarded for each correct answer, 1.5 points for any question left blank, and zero points for incorrect answers. That means the highest possible score is 150.

A strong score on the AMC 10 or AMC 12 can qualify you for the AIME. The cutoff scores vary each year depending on overall performance, but typically fall around 100 to 110.
