Entry fee for the Final
Qualifiers confirm their place in the Final by paying a single flat fee. Round 1 was free, and nobody who did not qualify ever pays anything.
One-off entry fee for the Round 2 Final, per participant.
Payment opens at PayPal. In the note to the payment, write the participant's full name and the e-mail address used to register — the payment may come from a parent's account, and the note is what ties it to the right place in the Final.
After you pay: tell us who you are
Paying the fee confirms your place, but the payment alone does not say whose place it is. Fill this in once the payment has gone through and we will match it to your registration. Nothing else is needed — no reply to our email, no other form.
Who pays
Only participants invited to the Final after Round 1. The Final is held on 15 November 2026, and the fee is due by 8 November 2026. Paying is what confirms the place; places not paid for by then are released.
What the fee covers
Grading of the Final papers, certificate printing and international shipping. It is not a registration fee for the olympiad: Round 1 is open to everyone at no cost.
Refunds
If we cancel a Final session, the fee is refunded in full. If you withdraw at least 48 hours before your session, the fee is refunded minus the PayPal processing fee.
After you pay
We match payments to invitations by name and email address and confirm your place by email, together with the joining details for the session. If nothing arrives within two days, write to us and we will find the payment.
