Biology Olympiad
coaching in Kolkata.

Our Biology Olympiad programme runs primarily online across India so students from all cities can access the same senior biology tutors and past-paper archive. Offline classroom coaching is available at our Gurugram, South Extension (Delhi), and Faridabad centres. Students in other cities join the online batches.

Most CBSE, ICSE, IB, and Cambridge schools in India register their senior students for NSEB (November paper) via IAPT. If your school does not administer NSEB, we help with direct registration through IAPT affiliated centres. Check with your biology teacher first.

Complete Olympiad Year programme (9-12 months, covers NSEB and INBO): $4,500 reference price with INR auto-shown on the pricing section (approximately ₹3.8 lakh equivalent). 1:1 Elite Mentoring with a senior olympiad tutor: $90 per hour. Small-Batch Weekend: $50 per hour. Pricing is identical across all India cities.

NSEB registration is administered by IAPT (Indian Association of Physics Teachers) through schools. In late August or September, your school biology teacher or coordinator registers interested Class 11-12 students through IAPT-affiliated centres. The November paper is sat at a designated centre (usually a city school acting as exam hub). If your school does not administer NSEB, you can still register directly through an IAPT-affiliated centre in your city — we help students confirm the nearest centre.

OCSC (Orientation-cum-Selection Camp) is a 2-3 week residential training camp at HBCSE (Homi Bhabha Centre for Science Education) in Mumbai held in April-May. It is Stage 3 of the Indian Biology Olympiad pathway. Selection is based on your INBO score — about 35 INBO performers are invited. OCSC includes rigorous theory and practical training with mock papers; there is no separate interview. The final 4 students who represent India at IBO are selected on combined camp performance.

INBO (Indian National Biology Olympiad) is Stage 2 of the Indian olympiad pathway, conducted by HBCSE in late January-early February. Only students who clear the NSEB cutoff (about 300 nationally) are invited to sit INBO. It is a theory-only paper testing university-level biology depth — practical assessment begins at OCSC. About 35 top performers advance to OCSC. INBO questions pull from Campbell Biology, experimental design, and data-interpretation.

Yes — any Indian school (CBSE, ICSE, IB, Cambridge, state boards) can register students for NSEB if the school has IAPT enrolment or uses an IAPT-affiliated exam centre. Student eligibility depends only on being a Class 11 or Class 12 student in an Indian school. We have successfully coached NSEB students from all major boards. If your school is not IAPT-registered, we help you enrol via the nearest IAPT centre (typically a senior school in your city).

The NSEB-to-INBO cutoff varies year-to-year but generally corresponds to the top ~300 students nationally, which translates to roughly the top 1% of registered candidates. The exact cutoff varies each year via the MAS rule (50% of the average of the top-10 scores) plus state quotas, and depends on paper difficulty. We coach students to target 70%+ as a safety margin above the typical qualifying band.

NSEB is held annually in late November — the 2026 paper is on 22 November 2026 (per the IAPT notification). Serious preparation should begin at least 9-12 months before — ideally starting Class 11 Q1 (July-August) to give full Campbell Biology coverage and 15 years of past-paper drill time. A 6-month sprint is possible for Class 12 students if NCERT is already strong. Our Complete Olympiad Year programme is sized to this timeline.

Yes. Any student enrolled in an Indian school (regardless of nationality) is eligible to sit NSEB and progress through the Indian pathway (INBO → OCSC → IBO). IBO team selection is based on country of schooling, not citizenship. This is why NRI students at IB schools in Gurugram, Bangalore, or Mumbai commonly compete in the Indian pipeline alongside Indian-national peers.
