Koobits Math Olympiad -

Because a worksheet tells you if you are wrong . KooBits teaches you why you are wrong and shows you how to fix it immediately.

This is a live competition where students compete globally on a single date. Instead, it is a self-paced, gamified question bank containing thousands of non-routine, high-order thinking problems drawn from past Math Olympiad papers across various countries.

The Fix: Set the KooBits account to "Challenge Mode" (disables unlimited hints). For Olympiad prep, a child should only get 3 hints per problem.
