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 wider syllabus than A level. It is hoped that participating in the BBO will encourage students to continue studying the biosciences beyond school.

The BBO 2018 will take place between 23rd - 31st January 2018. The competition consists of two, one-hour multiple choice tests taken online in schools under staff-supervised conditions.

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


Top scoring students are rewarded with publicly recognised certificates and medals, and will be offered the opportunity to attend an awards ceremony in London. 

How to register

The competition is open to post-16 students studying at school or college. Teachers can register their students for the BBO 2018 from 12th October 2017

Each school is eligible for two free places in the competition. Stepped fees are applied for each additional student entered, up to a maximum fee of £150:

  • 1-2 students registered from a school = free
  • 3-12 students registered = £10 each (max. cost for 12 students is £100)
  • 13- 22 students registered = £5 per additional student (max. cost for 22 students is £150)
  • 23 or more students registered = £150 total entry fee

The deadline to register students for the BBO 2018 is 12th January 2018.

International Biology Olympiad

Top scoring 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 2018 will be held in Tehran, Iran between 15th - 22nd July 2018.
