PUMaC (Princeton University Mathematics Competition) is an annual high school math competition organized entirely by student volunteers in the Princeton University Math Club. Now in its 20th year, PUMaC brings together teams from across the US and internationally to compete across four rounds on the Princeton University campus each November.
Competition rounds:
| Round | Format | | ----------------- | ------------------------------------------------------------------------------------------------------------------------------ | | Power Round | Proof-based team test released one week before competition day; all team members collaborate and submit before competition day | | Individual Tests | Each student selects two subject tests from: Algebra, Combinatorics, Geometry, and Number Theory | | Team Round | All team members work together on a collaborative problem set on competition day | | Individual Finals | Top scorers from Individual Tests advance to a live finals round |
Two participation tracks:
- Main Competition (in-person at Princeton): Teams compete in all four rounds; $12.50 per student
- Power Competition (remote): Teams complete the Power Round only and are ranked separately; $5 per student — open to teams that cannot travel to Princeton
International teams:
International teams are explicitly welcome and use the same registration form as US teams; they are considered separately in admissions. Regional mirrors for students who prefer local competition:
- Africa: PUMaC Africa mirror
- China: Mirror run by ASEEDER
Skill divisions:
PUMaC offers Division A (more advanced) and Division B (accessible to students newer to competitive math). Each team competes in one division as a whole; teams not affiliated with a single high school must compete in Division A.
