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 2019 took place between 1st - 8th February 2019. 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 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.

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 2019 will be held in Szeged, Hungary between 14th - 21st July 2019; Foreign and Commonwealth Office guidance will be consulted in planning for this event.
