British Biology Olympiad 2026
UK Biology Competitions (UKBC)
Apply Now
The British Biology Olympiad (BBO) is an online problem-solving competition aimed at post-16 students (typically A-level / Y12-Y13). The BBO challenges students with biology problems and rewards top performers with publicly recognised e-certificates (Gold, Silver, Bronze, Highly Commended, Commended, Participation).
The papers assume knowledge of common A level biology topics but focus on applying principles to unfamiliar scenarios.
The competition in 2026 runs from 19 January to 28 January and consists of two 45-minute multiple-choice papers taken online under teacher-supervised examination conditions; papers may be taken together or separately. Teachers register and invigilate students via the UKBC exam portal; all students need access to an internet-connected device.
High-scoring students are invited to further practical and theoretical training and assessments as the first stage of selection for the International Biology Olympiad (IBO).
