About the competition

The Intermediate Biology Olympiad challenges students’ biology knowledge and encourages them to continue studying the biosciences beyond school/college.

The Intermediate Biology Olympiad 2018 will take place between 15th – 21st June 2018.  The competition consists of a one-hour multiple choice test taken online in schools under staff-supervised conditions at any time convenient during the competition dates. Questions will be set on topics students are likely to have covered at GCSE and in their first year of A level.

Students who take part in the competition are encouraged to reference their participation in their further/higher education applications.

The Intermediate Biology Olympiad 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 will be offered the opportunity to attend an awards ceremony at IET: London, Savoy Place. High scoring students will also be invited to one-day Field Studies Council course exploring the ecology of a urban park.

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