In the USA, the road to the IBO runs through USABO. We coach the full ladder — Open, Semifinal and National Finals — live in your US time zone, with AIIMS-trained biology faculty (AIIMS — India’s apex medical institute, peer to Harvard Medical School in selectivity) and a past-paper-saturation method.
The path runs through the USA Biology Olympiad (USABO). We coach every stage.
USABO Open Exam (3 February 2027, 4 pm ET (online)) — 50-minute online multiple-choice exam, no penalty for guessing, through a registered school
USABO Semifinal (2 March 2027, 4 pm ET) — 120-minute online exam in three parts: multiple choice, multiple true/false, and short answer or essay; top ~10% of Open advance
USABO National Finals (20–30 June 2027) — 12 days: 10 of instruction and 2 of testing; 20 finalists
Top 4 finalists form Team USA for the International Biology Olympiad

New to the pathway? How to make the US IBO team — the full USABO pathway, stage by stage.
Through USABO: the Open Exam on 3 February 2027, the Semifinal on 2 March 2027 (the top ~10% of Open advance, and must be US citizens or green-card holders), then the National Finals on 20–30 June 2027. The top 4 finalists represent the USA at the International Biology Olympiad. We coach every stage.
Any student in grades 9–12 at a registered US school can sit the Open Exam, regardless of citizenship; advancing to the Semifinal and beyond requires US citizenship or a green card. Registration is handled by the school or an authorised USABO Center (fee $125 per school, due 23 October 2026; schools close 15 November, students 22 November 2026). Parents cannot register a student directly.
Roughly the top 10% of Open Exam takers advance to the Semifinal — CEE sets the exact cutoff each year from the actual score distribution, so there is no fixed number. The Semifinal is a longer, harder paper with free-response questions, which is where undergraduate-level depth (Alberts, Lehninger) starts to matter. We coach to clear the cutoff comfortably rather than scrape it.
The top 50 Semifinal scorers sit a pretest and interview and 20 are selected for the National Finals (20–30 June 2027) — a 12-day residential camp with theory and hands-on lab practical rounds. Performance across that camp determines the final ranking, and the top 4 students are selected as Team USA for the International Biology Olympiad. So the funnel is Open Exam → Semifinal → National Finals (top ~20) → top 4 to the IBO. We prepare candidates specifically for the camp’s lab-practical and free-response demands, not just the written rounds.
Registration opened on 7 August 2026 and closes on 15 November for schools and 22 November for students; the Open Exam is on 3 February 2027; the Semifinal on 2 March; the National Finals on 20–30 June 2027; and the IBO itself (Warsaw, 18–25 July 2027) takes place in July. We map your preparation backward from the February Open so foundational reading is done before the new year and the winter is spent on past-paper saturation.
Campbell-based, IBO-syllabus-depth biology coaching with AIIMS-trained faculty — molecular and cell biology, genetics, physiology, ecology, evolution, plus practical-exam and past-paper drilling. IBO-syllabus mastery transfers across every national selection route, so the same depth prepares you for both your national olympiad and the IBO itself.
