- Who can enter
- Under 20, pre-university — via your country's national team selection
- What it costs
- Free for you: you get there through your national olympiad, and the national team's costs are covered by the host country and your national organiser.
- When it closes
- We could not confirm this year's date against the organiser's own page, so we are not showing a countdown for it. Last published: Finals each July; national selection runs the winter before.
Sending this to someone sends the four facts above, not just a name — they will see who can enter and what it costs before they decide.
