The United States of America Mathematical Olympiad (USAMO) is one of the most prestigious math competitions for high school students in the US. Just qualifying is a significant achievement. This guide walks through how to prepare for and do well in the USAMO.
Understanding the USAMO
The USAMO is the final stage of the American Mathematics Competitions (AMC) series. To reach it, you first do well on the AMC 10/12, then on the American Invitational Mathematics Examination (AIME). Only about 250 students qualify each year, so it’s extremely selective.
Format
- A two-day exam with three problems each day.
- Each day lasts 4.5 hours.
- Problems are proof-based, requiring rigorous arguments.
- Topics span algebra, combinatorics, geometry, and number theory.

Tip 1: Master the fundamentals
Before olympiad-level problems, make sure you have a strong grasp of the fundamentals. Solid understanding across all areas of math, even the ones you consider “lesser,” builds your skills from the ground up, especially since USAMO problems love to mix and match topics. The problems are proof-based, so you need the underlying principles, not just the answer.
Having a solid foundation is really the key to success.

Tip 2: Study past USAMO problems
Get familiar with the style and difficulty by working through past USAMO exams. The Art of Problem Solving (AoPS) site is an excellent resource. Make solving complex problems a daily habit, that consistency pays off at the USAMO.
Pro tip: time yourself while practicing at home. It helps you learn your strengths and weaknesses so you can work on them.
Tip 3: Find math circles and camps
Join a local math circle, or attend an intensive camp like the Mathematical Olympiad Summer Program (MOP) if you qualify. These offer strong training and exposure to advanced concepts.
If you did MathCounts in middle school, you’ve already started. If not, join a math team at your school now. It’s a structured way into competitive math and a chance to learn alongside peers.

Tip 4: Read advanced math books and resources
Good resources matter for the USAMO. The Art of Problem Solving has many links to books, websites, and other materials worth using.
Tip 5: Manage your time
Time management is crucial in a timed exam, so watch how long you spend on each problem. If you’re stuck, move on and come back. The goal is to maximize your score, not to get bogged down. Solving a few problems thoroughly often beats spreading yourself thin across all of them.
Mental preparation
Doing well at the USAMO takes mental fortitude as much as math knowledge.
1. Be persistent
USAMO problems are hard by design. Don’t get discouraged if a solution doesn’t come right away.
2. Manage stress
Build stress-management habits like deep breathing to stay calm during the exam.
3. Learn from mistakes
Every wrong attempt is a chance to learn. Analyze your mistakes and understand where you went wrong.
Even if the USAMO doesn’t go your way, it’s not the end. Plenty of other competitions will test your skills. If you’re interested in research, one to consider is the IRO.
International Research Olympiad (IRO)
The International Research Olympiad (IRO) is built around analytical and critical thinking, the skills that matter in real research. It rewards rigorous thinking and big-picture problem-solving over memorizing formulas, and it leaves students with a deeper interest in scientific inquiry.
Conclusion
The USAMO is a challenging but rewarding goal. It takes dedication, hard work, and a genuine love of math. The skills you build preparing for it will serve you well no matter the outcome. Stay curious, take on the challenges, and enjoy the math along the way. Good luck.
