The competition is for students in their first year of post-16 education, e.g. the first year of A levels in England, 16-17 year-olds. Students in their final year of pre-university education should be entered in to the British Biology Olympiad instead.
Students from all types of schools, and from anywhere in the world can take part.
The competition assumes knowledge of the common elements of the beginning of biology A-level syllabi.
The medal boundaries are set using only students from UK schools, and are then awarded to all participating students.
