How OlympiadCloud helped students master their olympiads and advance their scores.

Aryan S.

Grade 9 · Pune

I practised 3 full-length IMO tests on OlympiadCloud every week for two months. The explanations helped me understand what I was getting wrong. I ended up with a Gold Medal and State Rank 4.

Grade 7 · Chennai

NSO Level 2 felt exactly like the mocks I'd been doing here. The timer pressure is real — you can't pretend it isn't counting. I cleared Level 2 for the first time this year.

Parent of Rohan K.

Grade 4 · Bengaluru

My son was struggling with English comprehension. Two months of IEO practice on OlympiadCloud made a visible difference — he scored in the top 50 nationally for his class.

Meera T.

I used to freeze during timed exams. Doing twenty full-length mocks changed that completely. My IGKO score went from below average to Distinction.
