How do I qualify for USAMO?

Through a high USAMO index (AMC score + 10 × AIME score), typically ≥ 210–215. We help with the entire AMC → AIME → USAMO pipeline.

What math background do I need?

You should have scored well on AIME (8+) and be comfortable with proof-based mathematics. We develop rigorous proof skills from there.

What level are our tutors?

All our tutors have either scored in the top tier of the exam they teach, hold a degree in the relevant subject from a top university, or have direct competition/olympiad experience. We don't hire general tutors.

How many sessions do I need?

Depends on your starting level and goal. We offer 8-session intensives, 3-month tracks, and full-year programs. Your consultation will determine the right fit.

Do you offer group classes or only 1-on-1?

We offer both. 1-on-1 is most popular for olympiad and university entrance prep; small group classes (3-5 students) are available for AP and GCSE/A-Level curricula.

Absolutely. We match you to the best tutor for your subject, but if the fit isn't right, we'll rematch at no cost.

Is there a trial session?

Yes — your first 30-minute consultation is free. This is a real teaching session, not a sales call.

About this Exam

What Is USAMO?

The USA Mathematical Olympiad (USAMO) is a prestigious proof-based competition for the top ~500 students in the US. Each of the 6 problems requires rigorous written proofs over two exam days (4.5 hours each). Top scorers are selected for the Mathematical Olympiad Summer Program (MOSP) and the US IMO team.
