Olympiads
Every olympiad, 2026–27
The olympiads Indian students sit in Classes 2–12, in one place: who runs each one, who can take it, how it works and when it usually happens. Dates and fees change every year, so every page links the official site.

Olympiads and the Ado Rank
An olympiad is one exam on one day. The Ado Rank is a standing earned every day, against students the same age. They go well together: daily practice builds the habit and speed an olympiad rewards.
Practice a little, every day
Ado is a free daily quiz in maths, science, English, GK and reasoning, ranked only against students the same age. The Ado Rank it builds never resets.
For parents of students aged 6–17.
