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 2018 took place between 23rd - 31st January 2018. The competition consists of two, 45-minute multiple choice online tests. These are taken in schools under staff-supervised 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 and medals, and will be offered the opportunity to attend an awards ceremony at IET: London, Savoy Place.

Every student who takes part in the competition is eligible to receive free BioNet membership for one year.
