The British Informatics Olympiad is the computing competition for schools and colleges. We are proud to present BIO 2023.
The 2023 British Informatics Olympiad

We are now distributing the BIO 2023 first round paper. Verified registrations meeting our eligibility requirements received on or before 3 December were sent the paper on 4 December. New (verified) registrations after this date should receive the paper within three days.

If you have not received an expected response to a registration enquiry or receipt of the paper, and have tried the obvious remedies (including checking your spam folders) please try to contact us using an alternative method to your previous enquiry. Every year we find a small number of school email servers have very aggressive filters which silently drop some external communications.

If you completed the registration form successfully and saw this confirmation page you details were sent to us and you will not receive any additional confirmation unless you have written to us directly.
