Olympiad pages
- Every fact is checked against the organiser’s own website, which each page links.
- Each page shows the date it was last checked. We review every page each March, before registrations open, and whenever an organiser announces a change.
- We don’t print fees or exact exam dates, because they change every year. We say when an exam usually happens and send you to the official site.
- Ado is not affiliated with any olympiad or its organiser, and no organiser pays to appear here.
How pages are written
Drafts are researched and written with AI help, then read and approved by our team before they are published. We don’t publish invented statistics or quotes.
Practice questions
The practice pages show sample questions from Ado’s question bank, written with AI help. Questions shown on this site are never used in ranked play, so publishing their answers can’t help anyone climb a rank.
