Official Brochure 2026-27What is the National Olympiad Programme?
The National Olympiad Programme is India's most recognized academic talent search in foundational sciences. Organized jointly by the Indian Association of Physics Teachers (IAPT) and the Homi Bhabha Centre for Science Education (HBCSE - TIFR), the programme aims to promote excellence in science among pre-university students and select official Indian delegations for the annual International Olympiads in Astronomy, Biology, Chemistry, and Physics.
Unlike regular competitive tests or commercial scholarship exams, the Olympiads assess deep conceptual understanding, analytical thinking, mathematical modeling, and rigorous laboratory skills across a structured multi-tier selection process.
NSEA, NSEB, NSEC and NSEP Explained
Stage-I consists of four distinct subject examinations conducted by IAPT:
NSEA (Astronomy)
National Standard Examination in Astronomy
Focuses on Physics, Mathematics, and elementary Astronomy for students aspiring to participate in the International Olympiad on Astronomy and Astrophysics (IOAA).
NSEB (Biology)
National Standard Examination in Biology
Tests advanced biological concepts, genetics, ecology, and experimental physiology leading to the International Biology Olympiad (IBO).
NSEC (Chemistry)
National Standard Examination in Chemistry
Assesses physical, organic, and inorganic chemistry problem-solving leading to the International Chemistry Olympiad (IChO).
NSEP (Physics)
National Standard Examination in Physics
Tests deep theoretical and conceptual problem-solving in mechanics, electromagnetism, and optics leading to the International Physics Olympiad (IPhO).

If your school is not a registered NSE centre, students can register directly on the official IAPT student enrolment portal (iapt.org.in) and choose the nearest available examination centre.
10 Practical Preparation Tips for Science Olympiads
- Build Strong Class X–XII Fundamentals: Master NCERT core textbooks thoroughly before moving to advanced problem collections.
- Understand Concepts Over Formulas: Olympiad problems test the "why" and "how", demanding conceptual derivation rather than memorization.
- Solve Past Olympiad Papers: Practice past 10 years' NSE and INO question papers from HBCSE archives to gauge question style and difficulty.
- Sharpen Mathematical Skills: Numerical problem-solving with calculus, coordinate geometry, and approximations is vital for Physics and Chemistry.
- Practice Multi-Concept Problems: Train on problems connecting multiple disciplines (e.g., thermodynamics with chemical kinetics).
- Strengthen Experimental Thinking: Understand laboratory procedures, error analysis, significant figures, and experimental graphs.
- For Astronomy (NSEA): Solidify mechanics, optics, gravitation, trigonometry, and basic celestial coordinate systems.
- Master Time Management: Simulate 2-hour Mock Test with negative marking to optimize question selection.
- Track Official Updates: Check the official IAPT and HBCSE portals weekly for Admit Card and notifications.
- Avoid Rote Learning: Rely on standard university-level reference textbooks (Halliday-Resnick for Physics, Campbell for Biology, Atkins/Clayden for Chemistry) alongside school curriculum.
