The AMC 8 is one of the most popular math contests for middle school students in the United States. It's a single multiple-choice test that rewards clever thinking more than advanced content, which makes it a great first contest for students who enjoy puzzles. Many students take it several years in a row and watch their scores grow.
This guide explains what the AMC 8 is, who can take it, how it's scored, what's on it, and how to register. For a wider look at the contest landscape, see our parent's guide to math competitions for kids.
Check maa.org for current details. The Mathematical Association of America (MAA) sets the date, rules, eligibility and fees each year, and these can change. Use this guide for the big picture and the official MAA site for anything you need to act on. BAMS Academy is not affiliated with the MAA.
What is AMC 8?
AMC stands for American Mathematics Competitions, a program run by the MAA. The AMC 8 is the middle school level of that program. Older students can go on to the AMC 10 and AMC 12, which lead to more advanced invitational contests.
The AMC 8 is designed so that every student who takes it can solve some problems, while the last problems challenge even the strongest students. The goal is to build interest in problem solving, not only to find winners.
AMC 8 format
The AMC 8 has traditionally been a single sitting of 25 multiple-choice questions in 40 minutes, with five answer choices per question. Students work individually and may not use calculators. Scratch paper, pencils and similar basics are usually allowed. Confirm the current format and allowed materials on maa.org before the test.
The questions start relatively gentle and get harder as the test goes on. Most students won't finish every problem, and that's expected.
AMC 8 eligibility
The AMC 8 is intended for students in grade 8 or below. The MAA also sets an age limit, and younger students, including talented elementary students, are often allowed to take it. Because the exact rules are set each year, check the eligibility section on maa.org before registering.
Students take the AMC 8 at a school or another site that has registered with the MAA. Home-schooled students or students whose school doesn't participate can often find a nearby site; the MAA website explains the options.
AMC 8 scoring
The AMC 8 has traditionally awarded one point for each correct answer, with no points taken away for wrong or blank answers. That means a student's score is simply the number of questions answered correctly. Because there is no penalty for a wrong answer under this system, it usually makes sense to answer every question, making an educated guess where needed. Always confirm the current scoring rules on maa.org.
The MAA recognizes high-scoring students with honor roll and other awards, and schools may receive certificates for their top participants. The thresholds for these awards are set by the MAA and published after each contest.
What topics are on the AMC 8?
The AMC 8 draws on math that most middle school students have seen, but uses it in creative ways. Common topic areas include:
| Topic area | What it might involve |
|---|---|
| Arithmetic and number sense | Fractions, decimals, percents, order of operations, estimation |
| Number theory | Factors, multiples, primes, divisibility, remainders |
| Counting and probability | Listing cases, arrangements, simple probability |
| Geometry | Area, perimeter, angles, the Pythagorean theorem, basic 3D shapes |
| Algebra and patterns | Simple equations, ratios, rates, sequences |
| Logic and word problems | Multi-step reasoning, puzzles, working backward |
Most problems need careful reading and a clever approach rather than a formula from a textbook.
Two sample problems
These give a taste of the style. They are BAMS Academy practice — not official competition problems.
Sample 1
A number leaves a remainder of 2 when divided by 5, and a remainder of 3 when divided by 4. What is the smallest positive number that does this?
Solution: numbers with remainder 2 when divided by 5 are 2, 7, 12, 17, 22 and so on. Check each one divided by 4: 2 leaves 2, 7 leaves 3. So the answer is 7.
Sample 2
A rectangle has a perimeter of 30 and its length is twice its width. What is its area?
Solution: call the width w, so the length is 2w. The perimeter is 2(w + 2w) = 6w = 30, so w = 5 and the length is 10. The area is 5 × 10 = 50.
Notice that neither problem needs advanced math. Both reward organizing information and trying a systematic approach.
How to register for the AMC 8
- Ask your child's school. Many schools register as a site each year, often through a math teacher or club sponsor.
- If the school doesn't participate, look on maa.org for guidance on finding another registered site.
- Note the deadlines. Sites register ahead of the contest, so ask early in the school year.
- Confirm the test date and time with the site, and check what your child needs to bring.
Is the AMC 8 right for my child?
The AMC 8 may be a good fit if your child:
- Enjoys puzzles, brain teasers or "tricky" math questions
- Finds regular class math easy and wants more of a challenge
- Likes working independently
- Can handle not finishing a test without feeling discouraged
It may be worth waiting a year if your child is still building confidence with fractions and basic geometry, or if timed tests cause a lot of stress right now. There's no rush; many students first take the AMC 8 in 7th or 8th grade.
How to get started with preparation
You don't need a formal program to begin. A few habits go a long way:
- Shore up the basics. Fluent work with fractions, percents and ratios saves time on test day.
- Practice problem-solving strategies: draw a diagram, make a list, look for a pattern, work backward.
- Try a small set of problems each week and review every mistake carefully.
- Use official resources from the MAA where available, and follow their terms of use.
- Add timed practice later. Build understanding first, then practice working within a time limit.
BAMS Academy's competition-style practice by grade offers original practice questions with a full explanation for every answer. You can find all competition resources on our competition prep page.
Common test-day mistakes to avoid
- Misreading the question. Words like "not," "at least" and "how many more" change the answer. Underline them.
- Spending too long on one problem. Every question is worth the same, so a stuck problem can cost several easier ones later in the test.
- Skipping the answer choices. Sometimes testing the choices, or ruling out impossible ones, is faster than solving from scratch.
- Arithmetic slips under pressure. Write steps clearly on scratch paper, even for problems that feel easy.
- Letting a hard problem shake confidence. The last questions are meant to be difficult for almost everyone. Stay calm and keep going.
What happens after the AMC 8?
For many students, the AMC 8 is the start of a longer math journey. Some go on to take the AMC 10 in high school, join a MathCounts team, or explore other math clubs and programs. Others simply enjoy the challenge once a year. Both paths are valuable. The skills built along the way, like persistence and creative problem solving, help in every math class.
Frequently asked questions
Can elementary students take the AMC 8?
In many cases, yes. The AMC 8 is aimed at students in grade 8 and below, and younger students often participate. Check the MAA's current eligibility rules on maa.org to be sure.
Is a calculator allowed on the AMC 8?
Calculators have traditionally not been allowed on the AMC 8. Check the current rules on maa.org before test day, since the MAA sets what materials are permitted.
What is a good AMC 8 score?
It depends on the student and their goals. A first-time 6th grader and an experienced 8th grader will aim for different results. Improvement from one year to the next is a great goal. The MAA publishes award thresholds after each contest.
