Hey! Wanted to share with you all the launch of the MathDash Math Olympiad Rating and Leaderboard!

Proof-based competition: Solve and prove each question.

Problem difficulties: The six problems on a recent International Math Olympiad should be ratings ~2100/2500/3000/2100/2500/3000. Rating 1000 should be approachable for anyone with any math background!

Grading: Submissions graded ASAP (likely after the round).

Regrade policy: Dispute scores in the post-contest discussion chat. Grading is at our discretion.

Good luck and happy solving!
