The core of the application is the problem set, which is designed to assess your mathematical thinking and creativity. Once applications open, register on the PROMYS application portal to access the problem set.

You’ll want to work on these problems carefully, showing your reasoning clearly and providing solutions along with short summaries explaining your approach. For example, here are some of the types of problems in the PROMYS 2025 application problem set:

• Number theory and pattern recognition (e.g., minimal missing integers in an infinite grid)
• Infinite sequences and geometry in unusual contexts (e.g., hare and flea chase problem)
• Set construction rules involving fractions and algebraic manipulation
• Combinatorial counting with constraints
• Coloring and adjacency problems in grids popular in graph theory
• Polynomial expansions and parity investigations
• Geometric approximations involving integer-coordinate proximity
• Line intersections with infinite repeating grids and combinatorial variations

Submit your completed math problem set by the application deadline, usually in early March.

Take your time working through the problems. Focus on explaining how you approached each problem, as the admissions team values your thought process more than just the final answer. Don’t hesitate to revisit problems after some time to improve your solutions and explanations. Double-check your work to ensure that explanations are clear and concise.
