Two Rounds. One Philosophy.
We aren't here to test your memory. We are here to see how you handle ambiguous, open-ended astrophysics problems when standard formulas leave you stranded.
Round 1: The Open MCQ
Developed by experienced olympians, the Open Round is a fast-paced, exclusively multiple-choice exam designed to test your foundational physics and astronomy knowledge.
Round 2: The Playground
Breeze the MCQ, and you reach the Invitational. During this 3-day window, you will work against your intuition, face real-world problems, and write custom code to solve non-linear differential equations.
Something for Everyone
Whether you are a gold medalist at the IOAA or just starting out, the exams are designed to push your limits and expand your horizons in astrophysics, no matter where you are in your journey.
