- Natural Sciences
- Who can enter
- Pre-university students worldwide, under 20 — online; qualification is free
- What it costs
- The qualification and pre-final rounds are free. A small fee (about EUR 20) applies only at the final round, and it is waived on request for students who cannot pay.
- 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: Qualification and final rounds over the summer — entirely online.
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.
