CBSE Class 12 Physics PYQ. Derivations. Numericals. Diagrams. Free.
Physics is the hardest subject to score in for most Class 12 students — not because the concepts are impossible, but because the board paper tests derivations and numericals in a very specific format. Previous year questions show exactly what that format looks like. Here's 10 years of it.
How to use CBSE Class 12 Physics PYQs to score above 60
Why Physics is the hardest to score in — and what changes that
Most Class 12 students target 70/70 in Maths and accept 50/70 in Physics as a given. The gap is usually not concept understanding — it is not knowing how to write a derivation in the CBSE format, or missing the specific numerical steps the marking scheme expects.
Previous year questions with official marking schemes solve this problem directly. When you read how CBSE's marking scheme allocates marks across a 5-step derivation, you start writing derivations differently. This change in approach — not studying more Physics — is what moves scores from 50 to 65.
What 10 years of Class 12 Physics PYQs reveal
Electrostatics and Current Electricity together appear in every paper and carry 14–16 marks. Magnetism (Biot-Savart Law, Ampere's Law, force on a current-carrying conductor) is tested every year — derivations and applications both. Electromagnetic Induction and Alternating Currents carry 8–10 marks consistently.
Optics: Ray Optics (mirror/lens formulae, refraction, total internal reflection) and Wave Optics (Young's double slit, diffraction) are both tested every year. Modern Physics: Photoelectric effect, atomic models, and nuclear reactions appear consistently in the last 5–8 marks of the paper.
Derivations — where most students lose marks they shouldn't
Class 12 Physics derivations are the most predictable component of the board paper. The same 12–15 derivations appear in rotation: electric field due to a point charge, Biot-Savart derivation for a circular loop, mirror formula, lens formula, expression for torque on a dipole. These have not changed in 10 years.
CBSE marking schemes allocate marks to specific derivation steps — not just the conclusion. A student who knows the 5 required steps of the mirror formula derivation and writes them clearly earns 5 marks even if their final expression has a sign error. Write derivations as steps, with clear labelling of what each line represents.
How to practise Physics PYQs — by question type
Separate your practice by question type: derivations, numericals, and diagram questions. Collect all derivations from 10 years and practise writing them in full — not reading them. Then collect all Electricity numericals and work through them: Kirchhoff's Laws, Wheatstone bridge, internal resistance. Then Ray Optics numericals.
Full-paper practice comes after chapter-type fluency. Without type-specific fluency, timed papers just expose gaps without helping you fill them. ClearSteps lets you filter by chapter and question type — pull all Electrostatics numericals in one session, all Magnetism derivations in another.

Frequently asked questions
Where can I get free CBSE Class 12 Physics PYQ?
CBSE Class 12 Physics previous year questions are available free on ClearSteps — 2015 to 2025, with official marking schemes and chapter-wise filters. Full papers are also available from cbse.gov.in.
Which chapters appear most in CBSE Class 12 Physics PYQ?
Electrostatics and Current Electricity appear in every paper and carry the most marks (14–16 combined). Magnetism (Biot-Savart, Ampere's Law) is tested every year. Optics (Ray Optics and Wave Optics) together carry 10–12 marks per paper. Electromagnetic Induction and Alternating Currents (8–10 marks) and Modern Physics (5–8 marks) round out the consistent high-weight chapters.
How do I score more than 60 in CBSE Class 12 Physics?
Master the 12–15 recurring derivations first — they are fully predictable and worth 15–20 marks collectively. Practise Electricity and Optics numericals chapter-by-chapter until the approach is automatic. Solve at least 3 full papers under timed conditions and compare your derivations step-by-step to the marking scheme. The marking scheme tells you exactly which steps to write.
How many steps does a Physics derivation need in CBSE Class 12?
CBSE marking schemes allocate one mark per key step in a derivation. A 5-mark derivation typically has 5 required steps: stating the physical setup, writing the starting equation, intermediate algebraic steps, applying the relevant law or theorem, and stating the final result. Writing these steps clearly — with a diagram where applicable — is what earns full marks.
How many years of Physics PYQ should I solve for Class 12?
For type-based practice: pull derivations and numericals from all 10 years by chapter. For full-paper practice: solve at least 5 complete papers (current year sample paper + 4 recent board papers) under exam conditions. Check every answer against the official marking scheme — not just right or wrong, but which specific steps earned marks.
