About the competition

The British Biology Olympiad (BBO) challenges and motivates students with an interest in biology. The competition allows students to demonstrate their knowledge by offering a wide ranging syllabus. 

The BBO 2020 took place between 31st January - 7th February 2020. The competition consists of two, 45-minute multiple choice online tests. These are taken in schools under staff-supervised exam conditions at any time convenient during the competition dates.

The BBO also provides a means of selecting a team to represent the UK at the International Biology Olympiad (see below).

The BBO is organised by the UK Biology Competitions committee and administered by the Royal Society of Biology.


Top scoring students are rewarded with publicly recognised certificates.

How to enter

The British Biology Olympiad 2020 is now closed for registrations.

The competition is open to post-16 students studying at school or college worldwide.

Each school is eligible for five free places in the competition. Stepped fees are applied for each additional student entered, up to a maximum fee of £100:

  • 1-5 students registered from a school = free
  • 6-25 students registered = £5 each (max. cost for 25 students is £100)
  • 26 or more students registered = £100 total entry fee.

Schools with existing competition payment arrears will not be able to participate in the British Biology Olympiad 2020.

International Biology Olympiad

The top-scoring sixteen students in the BBO will be invited to complete further practical and theoretical assessments in order to select a team to represent the UK at the International Biology Olympiad (IBO). The IBO 2020 has been cancelled, however a remotely-conducted IBO Challenge will instead take place; UK Government and Foreign and Commonwealth Office guidance will be consulted in planning for this event.
