A free, open-source platform for AMC, AIME, and USAMO preparation.
USAMO Guide aims to provide a structured pathway from AMC → AIME → USAMO, combining curated learning resources, regular contests, and a contributor-driven community.
Most olympiad students currently rely on scattered resources across multiple sites. Our goal is to build a single platform where students can learn, practice, compete, and contribute.
A modular learning system covering:
- Algebra
- Number Theory
- Geometry
- Combinatorics
Each topic includes explanations, curated problems, and full solutions organized by increasing difficulty.
We plan to host recurring online contests with:
- Timed competition environments
- Automatic scoring for objective rounds
- Manual grading for proof-based problems
- Global rankings and leaderboards
This allows students to benchmark their progress and compete internationally.
USAMO Guide is community-built.
Contributors can help by:
- Writing learning modules
- Creating problems and solutions
- Reviewing content
- Helping with contests
Contributors receive public recognition and the chance to build something meaningful for the olympiad community.
See docs/Math_Topic_Template.md for content guidelines. All contributions are welcome! To get started, simply pick an issue you'd like to work on, leave a comment, and submit a Pull Request!
The USAMO Guide is run by the USAMO Guide team. We're looking for content authors to help us improve the Guide.

We would like to express our sincere appreciation to the USACO Guide team and contributors. Their open-source work served as an important reference while building USAMO Guide. The structure, engineering decisions, and overall philosophy behind the project were incredibly helpful as we developed our own platform.
In particular, the availability of their codebase made it significantly easier for us to understand how a large educational resource platform can be organized and maintained. Many aspects of our development process were informed by the design patterns and infrastructure used in USACO Guide. We are grateful to their team for openly sharing their work and helping make projects like this possible.
