💡 Expert Tip by Saransh Gupta, IIT Bombay AIR-41: In eSaral's JEE 2025 batch, students who completed all NCERT derivations with full understanding — not just memorisation — scored an average of 18+ more marks in Physics compared to those who only solved numericals. Derivations in NCERT are not just theory — they are direct board exam questions worth 3–5 marks each.
How to Study NCERT Physics Class 12 for Boards, JEE, and NEET?
The approach for boards and competitive exams is different but not contradictory. The NCERT book serves both — if studied correctly.
Step 1 — Read Theory and Understand Every Derivation
Physics is not a subject you can memorise. Read each NCERT chapter's theory carefully. For every derivation — Gauss's law, Biot-Savart law, Faraday's law, Bohr model — understand the logic step by step. Do not just copy the steps; understand why each step follows.
Step 2 — Solve All NCERT In-text and Chapter-end Questions
NCERT Physics has two types of questions — in-text questions (within the chapter) and chapter-end exercises. Solve both. Board exams directly lift questions from NCERT exercises. JEE and NEET use NCERT concepts as the base for harder questions.
Step 3 — Build a Formula Sheet for Every Chapter
Physics Class 12 has hundreds of formulas. After finishing each chapter, write all formulas, constants, and units on one page. Organise them by chapter. This becomes your go-to revision sheet. Key formula-heavy chapters: Ch 1, 2, 3, 4, 6, 7, 9, 11.
Step 4 — Practice Numericals Separately with Increasing Difficulty
Start with NCERT numericals. Then move to previous year board questions. For JEE, solve the JEE Main previous year Physics questions chapter by chapter. For NEET, focus heavily on Chapters 9, 11, 12, and 13, where concept-based MCQs dominate.
Step 5 — Revise Diagrams and Derivations Before Board Exams
CBSE board Physics papers award 3–5 marks for derivations and 2–3 marks for diagrams. Practise all key diagrams: electric field lines, circuit diagrams, ray diagrams for lenses and mirrors, p-n junction, and transistor configurations.
Study Phase | Timeline | Focus |
|---|---|---|
Chapter reading + derivations | June – September | All 14 chapters, both parts |
Formula sheet building | After each chapter | Ch 1, 2, 3, 4, 6, 7, 9, 11 priority |
Numerical practice | October – December | NCERT + PYQ numericals |
Board-level derivation practice | January | All NCERT derivations + diagrams |
Competitive exam MCQ practice | November – March | JEE PYQs or NEET chapter-wise MCQs |
Final revision | 2 weeks pre-exam | Formula sheets + short notes |
Why Is NCERT Physics Class 12 Important for Competitive Exams?
Is NCERT Physics Class 12 Enough for JEE Main?
NCERT Class 12 Physics is the mandatory foundation for JEE Main, but is not fully sufficient on its own. JEE Main tests NCERT concepts at a higher level of application and numerical complexity. Students need NCERT mastery first, then additional practice with JEE-level problems. However, approximately 30–40% of JEE Main Physics questions can be answered directly from solid NCERT understanding.
Is NCERT Physics Class 12 Enough for NEET?
For NEET, NCERT Class 12 Physics carries even more weight. NEET Physics questions are more concept-based and less numerically intensive than JEE. Students who thoroughly understand every concept and derivation in NCERT — especially in Chapters 9 (Ray Optics), 11 (Dual Nature), 12 (Atoms), and 13 (Nuclei) — can score 130–150 out of 180 in NEET Physics with NCERT alone as the primary source.
Can I Rely Only on NCERT Physics Class 12 for Board Exams?
Yes. NCERT is fully sufficient for scoring 90+ in CBSE Class 12 Physics board exams. CBSE sets all board questions from the NCERT theory, examples, derivations, and exercises. Students who complete all NCERT content and practise previous year board papers do not need any additional textbook for boards.

What is the NCERT Physics Class 12 Book in Hindi?
The NCERT Physics Class 12 Book in Hindi (भौतिकी) is the official CBSE textbook for Class 12 Physics, written entirely in Hindi. It covers all 14 chapters across two parts — from Electric Charges and Fields to Semiconductor Electronics — and is designed for both board exam preparation and as the foundation for JEE and NEET competitive exams.
Is NCERT Physics Class 12 Book in Hindi useful for JEE and NEET?
Yes. NCERT Physics Class 12 is the mandatory foundation for both JEE Main and NEET. For NEET, strong NCERT mastery — especially Chapters 9, 11, 12, and 13 — can deliver 130–150 out of 180 marks in Physics. For JEE Main, NCERT concepts form the base for 30–40% of Physics questions directly, with remaining questions requiring NCERT-plus-level numerical practice.
Which chapters in NCERT Physics Class 12 carry the most marks?
Chapters 1–2 (Electrostatics, 16 marks), Chapter 3 (Current Electricity, 17 marks), Chapters 4–7 (Magnetism + EMI + AC, 17 marks), and Chapters 9–10 (Optics, 18 marks) carry the highest board exam weightage. These six topic groups account for over 68 marks out of 70 in the theory paper.
Is the NCERT Physics Class 12 Book in Hindi easy to understand?
Yes. The NCERT Physics Class 12 Book in Hindi is written in clear, simple Hindi with step-by-step derivations, labelled diagrams, and worked examples. Hindi-medium students find it easier to grasp complex concepts like electromagnetic induction and wave optics when reading in their native language. For additional conceptual clarity, video explanations by Saransh Gupta Sir (AIR 41) are available on the eSaral App.
