The AIME (American Invitational Mathematics Examination) is one of the most challenging high school math competitions in the United States. Qualifying for AIME requires scoring in the top percentile on the AMC 10 or AMC 12, and succeeding on AIME itself can open doors to the USA(J)MO and, ultimately, the International Mathematical Olympiad. It's not a test you prepare for by reviewing class notes. AIME preparation requires a systematic approach, deep mathematical fluency, and a lot of focused problem-solving practice.
This guide covers the best training programs, self-study resources, and online practice options for students working toward AIME readiness.
The AIME is a 15-question, 3-hour exam administered by the Mathematical Association of America (MAA) as part of the AMC competition pathway. Every answer is an integer between 0 and 999—no multiple choice, no partial credit. Scoring is simply the number of correct answers (0–15).
To qualify, students must score in the top 2.5% on the AMC 10 (score of 103.5+) or top 5% on the AMC 12 (score of 100+). Most qualifiers are high school students in grades 9–12, though exceptional middle schoolers occasionally qualify through the AMC 10.
AIME problems draw from six major topic areas:
What makes AIME hard isn't the difficulty of any single concept—it's that problems often require combining multiple topics and finding non-obvious approaches. A geometry problem might require number theory to get the final answer into the 0–999 format. A combinatorics problem might resolve through an algebraic identity.
Art of Problem Solving is the single most important resource for AIME preparation. The AoPS platform offers:
If you're doing structured self-study for AIME, AoPS is the platform to build your work around. The community aspect is particularly valuable—seeing how other students approach problems you've attempted reveals thinking strategies you wouldn't develop in isolation.
For students aiming at USAMO or international competition, residential summer programs offer intensive training that accelerates progress dramatically:
These programs aren't purely AIME prep—they're broader mathematical training that makes competition preparation more effective by building the underlying skills that AIME requires. The alumni networks are also valuable for long-term mathematical development.
Private tutoring from a coach experienced in AIME-level competition math can dramatically accelerate preparation. Key qualities to look for in a coach:
Many AoPS community members who are strong competitors offer tutoring. Alumni of top math programs at MIT, Harvard, and similar universities who competed in AMC/AIME as high schoolers are also well-qualified. Rates vary widely—$50–$200/hour—but for students seriously targeting USAMO, a few months of weekly coaching sessions can be transformative.
Some high schools have strong math team programs that prepare students specifically for AMC/AIME competitions. These programs vary enormously—some are highly organized with dedicated coaches who design targeted practice sessions, while others are informal clubs with minimal structure.
If your school has a math team, get involved. Even a loosely organized team provides peer problem-solving partners, and working through problems with peers who are at similar levels builds competitive intuition faster than solo practice. If your school doesn't have a math team, consider starting one—the MAA provides resources for new teams.
For many students, self-directed preparation—supplemented by online resources—is the primary path. Here's how to structure it effectively:
If you're not yet consistently scoring at the AIME qualification threshold on AMC 10/12, that's where to start. AIME-level problem solving is built on AMC fluency. Work through AMC 10/12 past exams, aiming for reliable scores above the qualification cutoffs before transitioning to dedicated AIME preparation.
For each of the six AIME topic areas, do deep dives:
Don't try to master everything simultaneously. Pick two or three topics, develop real competency in them, then move to the next pair.
Once you've developed reasonable topic-level fluency, start taking full AIME practice exams under timed conditions. Three hours is a long time, and developing the endurance and pacing to work through 15 hard problems without losing focus is itself a skill that comes from practice.
Review every problem you didn't solve—not just wrong answers, but unsolved problems too. Look up the official solution or the AoPS community solution. Then try to reproduce the key insight without looking. That process—attempt, review, reconstruct—builds problem-solving intuition faster than any other method.
For students aiming at USAMO, eventually AIME problems become a stepping stone rather than a ceiling. Exposing yourself to USAMO problems, Shortlist problems from the IMO, and other olympiad-level material—even if you can't solve them—builds the mathematical maturity that makes AIME feel more tractable.
Several platforms offer AIME practice beyond AoPS:
The realistic timeline for a student starting from AMC qualification and aiming for a competitive AIME score (8+):
Students who qualify for AIME as freshmen or sophomores and put in consistent work often reach USAMO qualification by junior or senior year. The earlier you start building mathematical foundations, the more runway you have.
AIME scores of 1–3 are typical for first-time qualifiers. Scores of 6–9 indicate strong AIME ability. USAMO qualification requires an AIME score combined with AMC performance to clear a threshold that typically requires AIME scores in the 9–12 range depending on the year.
Don't be discouraged by low early AIME scores. Nearly every strong competition math student starts with scores of 1–3 on their first AIME attempt. The question is whether you're learning from each attempt and building the intuition that makes harder problems approachable.
