Biology · Expected
HBCSE / ATBS · Classes 11–12 · 2026–27 window: Late Jan / early Feb 2027 (expected)
Stage two in Biology — the gate to the IBO selection camp.
Entry only via NSEB qualification. Non-conventional, high-difficulty biology; partial credit for reasoning shown. Date confirms on HBCSE's portal near year-end.
Students of Classes 11–12. Subject focus: Biology. As with any olympiad, the best candidates are children who voluntarily enjoy the subject — an olympiad should stretch curiosity, not manufacture pressure.
Official information and registration: olympiads.hbcse.tifr.res.in. Always verify the current date, fee and eligibility on the organiser's own site before paying — organisers occasionally shift windows, and this page is a directory entry, not the organiser.
