The Hardest (and Most Fun) Astrophysics Challenge on Earth.

Forget standard exams. This is where Olympiad theory meets real world research. Claim the open round, unlock the invitational, and push your physical intuition and mathematical skills to their absolute limit.

Pre-Registration Open

Join the waitlist to secure your spot and get exclusive prep materials.

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.
