How to Prepare for NSEJS 2026 Using the Syllabus
Since the NSEJS 2026 syllabus is broadly equivalent to the Class 10 CBSE Science syllabus, students should first strengthen their fundamentals before moving to Olympiad-level questions.
1. Start with the complete syllabus
Break the syllabus into Physics, Chemistry and Biology and create a chapter-wise checklist. Complete the basic concepts from each chapter before moving to advanced problems.
2. Strengthen NCERT fundamentals
Read the relevant Class 9 and 10 NCERT Science chapters thoroughly. Focus on definitions, diagrams, formulas, reactions, examples and applications rather than simply memorising the text.
3. Focus on conceptual understanding
NSEJS questions can be non-conventional and require students to apply concepts to unfamiliar situations. After studying each topic, practise questions that require reasoning, calculation and interpretation.
4. Practice Physics numericals
Give extra attention to Motion, Force and Laws of Motion, Gravitation, Work and Energy, Electricity, Magnetism and Light. Solve numerical problems regularly and understand the reasoning behind each solution.
5. Strengthen Chemistry concepts
Revise chemical reactions, atomic structure, periodic classification, acids and bases, metals and non-metals, and carbon compounds. Practise balancing equations and application-based questions instead of relying only on memorisation.
6. Build strong Biology concepts
For Biology, focus on cell biology, life processes, reproduction, heredity, evolution and ecology. Use diagrams and flowcharts to understand processes and revise important terminology.
7. Solve previous-year NSEJS papers
Once a significant portion of the syllabus is complete, start solving previous-year papers under timed conditions. IAPT provides NSEJS question papers and answer keys as part of its examination resources.

NSEJS Syllabus 2026: Conclusion
The NSEJS syllabus 2026 covers important concepts from Physics, Chemistry and Biology, broadly based on the Class 9 and 10 science curriculum. Students should begin with NCERT textbooks, complete every subject systematically and devote additional time to concept-heavy topics such as electricity, light, chemical reactions, carbon compounds, life processes and genetics.
After completing the syllabus, students should solve NSEJS previous-year papers, revise difficult chapters and practise application-based questions under timed conditions. Regular revision, strong conceptual understanding and careful analysis of mistakes can help aspirants improve their accuracy, speed and confidence for NSEJS 2026.
