British Biology Olympiad


The British Biology Olympiad (BBO) is open to students around the world.

The 2020 competition took place between 31st January - 7th February 2020.


The BBO challenges and stimulates students with an interest in biology to expand and extend their talents. It enables students to demonstrate their knowledge and to be suitably rewarded with publicly recognised certificates and medals. 

The BBO is open to students in post-16 education studying at school or college. The competition consists of two, 45-minute multiple choice papers to be taken online under staff supervised exam conditions. 

In addition to encouraging and rewarding pupils in their studies, the BBO is the first stage in selecting a team to represent the UK at the International Biology Olympiad (IBO). The IBO seeks to challenge by both theory and practical tests some of the top pre-university biology students in the world, with over sixty countries taking part. 

Team selection for the International Biology Olympiad

The top-scoring sixteen students in the BBO will be invited to complete further 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.
