Our Take

CompeteMap's editorial perspective, based on our research and competition guide.

The competition consists of two, 45-minute multiple choice papers to be taken online while on-site at their registered school/college. The papers can be taken together or on separate occasions. - The International Biology Olympiad is an elite annual competition combining advanced theoretical and practical biology. - Students cannot register directly; each member country or region selects a team of up to four through its national olympiad. - In the UK, students must first take the British Biology Olympiad and then succeed in further training and assessment. - IBO preparation requires broad biological understanding, data analysis, laboratory skills, endurance and adaptability. - Official past papers are useful, but preparation should follow guidance from the student's national team leaders.
