A quiz-style competition for 13-15 year-olds.
Biology Challenge 2025
28th April to 7th May
Schools can register at any time until the competition takes place.
Schools will need login to their UKBC account in order to register for the competition. If you do not have an account, you can sign up here.
Biology Challenge is open to students aged 13 to 15
years old in:
- Y9/Y10 in England and Wales
- Y10/Y11 in Northern Ireland
- S2/S3 in Scotland, and
- equivalent year groups worldwide.
The competition consists of two, twenty-five-minute multiple choice papers to be taken online under staff supervised exam conditions.
Questions will be set on the school curriculum, but the competition will also reward those students whose knowledge of the subject has been increased by reading books and magazines, watching natural history programmes, taking notice of the news media for items of biological interest, and are generally aware of our natural flora and fauna.
Schools will be able to conduct Biology Challenge in whatever way best suits their pupils, ensuring that they enjoy participating and have a reasonable expectation of recognition for their achievements.
As well as being able to submit their pupils’ scores to the national competition, schools will be encouraged to award their own prizes and to make use of e-certificates provided for them.

I am a student/parent/carer
The British Challenge is administered as an exam. Therefore, only teachers can register candidates and invigilate the competition. If you would like to take part, please request your teacher to make the arrangements.
You could kindly explain that the competition sign-up is simple, the vast majority of participating schools receive at least one award, and that invigilation could be as simple as overseeing you during a lunch-break.
All contact between UKBC and students should be made via teachers (except for in-person events, such as the IBO).
