Many students wonder how to score 90 in Class 12 Physics, especially because Physics feels tough with so many formulas, numericals, and derivations. But the truth is — Physics is not hard if you do it the right way. With proper planning, clear concepts, and regular practice, you can easily get 90+ marks in your board exams. In this guide, you’ll learn the exact study plan, preparation tips & exam strategies followed by board exam toppers to score high in Class 12 Physics. Whether you find theory confusing or struggle with numericals, this article will show you simple steps that really help.
1. Know the syllabus and exam pattern first
Start by downloading or writing down the Class 12 syllabus & the exam pattern. If you know which chapters carry more weight, you can plan time better. Many toppers begin by finishing the full NCERT curriculum because board questions come mostly from there.
2. Use the right books — NCERT first, then practice books
Make NCERT your first book. Read every line and solve the examples in the book. After NCERT, use one good practice book or compilation for extra problems and previous year questions (PYQs). Extra books are useful only for more practice — don’t use many books or you will waste time.
3. Make a chapter plan and stick to it
Divide the whole syllabus into small parts and set weekly goals. For example:
- Week 1–2: Electrostatics (theory + 30 problems)
- Week 3: Current electricity (derivations + PYQs)
This keeps work simple and measurable. Many coaching guides suggest topic-wise plans to avoid last-minute panic.
4. Learn and write all derivations and formulas neatly
Derivations often carry marks. Learn the logical steps and practice writing each derivation on paper until you can reproduce it cleanly. Also make a one-page formula sheet per chapter. When you practice, always write steps clearly — presentation and correct units get extra marks.
5. Practice numerical problems smartly
Physics is mostly about understanding and solving problems:
- Start with solved examples in NCERT.
- Move to PYQs and sample papers (solve under timed conditions).
- Focus on topics like Electrostatics, Magnetism, EM induction, Optics and Modern Physics — these commonly appear in boards. Regular practice builds speed and accuracy.
6. Do past year papers and mock tests
Solve at least the last 8–10 years of board papers. Then take full-length mock tests every week in the last two months. Time management during the paper is as important as knowing answers. Mock tests help with speed and confidence.
7. Make short, clear notes for quick revision
Create simple notes: one line for concept, 2–4 bullets for steps, and a quick formula box. Use these notes for final 2–3 week revision. A clean list of derivations, formulas, and important experiment steps will save time and prevent forgetting.
8. Focus on frequent, high-yield topics
Some topics repeat often in board exams. Prioritize:
- Mechanics basics (if included),
- Electrostatics & Current electricity,
- Magnetism & Electromagnetic induction,
- Optics (ray and wave optics),
- Modern Physics (photoelectric effect, atomic models).
Give more practice time to these topics but don’t skip smaller chapters.
9. Improve answer presentation and handwriting
Marks are easier to get when answers are neat. Always:
- Write headings (e.g., “Derivation”, “Result”).
- Use correct units and box final answers.
- Number steps and draw clear diagrams with labels.
Good handwriting and tidy steps can win partial marks if calculations slip.
10. Handle theoretical questions well
For theory:
- Learn key definitions exactly (NCERT wording helps).
- Explain only what the question asks — be direct.
- Use diagrams and labels wherever possible.
Short, correct answers are better than long, vague answers.
11. Plan revision: 3-phase approach
- Learn: Read NCERT + solve examples.
- Practice: PYQs + sample papers under time.
- Revise: Use your notes and formula sheets daily in the last 2–3 weeks. Do 1 full paper every 3 days and correct mistakes immediately.
12. Last-minute strategy (1–2 weeks before exam)
- Do only high-yield PYQs and important derivations.
- Avoid learning new topics at the last hour.
- Sleep well and keep a light study schedule the day before exam. Several students report that concentrating on PYQs and NCERT in the last days gives the best gains.
13. Practical exam and internal assessment
Practicals are usually scoring if you do them properly. Keep your practical record neat and know the experiments and observations — examiners often give full marks for correct procedure and record. Don’t ignore internal assessments; they add to the final mark.
14. Common mistakes to avoid
- Relying only on theory without practicing numericals.
- Ignoring NCERT or skipping PYQs.
- Writing messy steps and skipping units.
- Studying too many reference books at once.
Fix these early and you’ll avoid losing easy marks.
Frequently Asked Questions
Q: Is NCERT enough to score 90+?
A: Yes — NCERT + PYQs + regular practice is usually enough to reach 90+ if you follow the plan.
Q: How many sample papers should I solve?
A: Aim for 20–30 full sample papers and 8–10 past year papers across your preparation time. Quality matters more than quantity.
Q: Should I memorize or understand?
A: Understand first. Memorize only definitions, final formula forms, and steps of derivations. Understanding helps with new or twisted questions.
If you follow this clear plan — study NCERT well, practice numericals and PYQs, write neat derivations, and take regular full-length mocks — you will be putting yourself in the best position to how to score 90 in class 12 physics. Keep calm, be consistent, and focus on smart practice. Good luck!
