CBSE Class 12 PYQ. 10 years. Every subject. Free.
Class 12 boards carry more weight than any exam before them. Previous year questions are not just practice — they are the most precise map of how CBSE sets the paper, every year. Here's how to use them properly.
How to use CBSE Class 12 PYQs the right way
Why Class 12 PYQs are different from everything else you've studied with
Class 12 boards are higher stakes and the PYQs reflect that. Unlike Class 10, where pattern exposure is the main benefit, Class 12 PYQs are essential for understanding answer format — how long a 3-mark Physics answer should be, what a derivation question expects versus a numerical, how Accountancy journals should be structured.
Students who score above 90% in Class 12 consistently report that working through previous year papers changed how they answered — not just what they knew. The format matters as much as the content.
What 10 years of Class 12 PYQs reveal by subject
Physics: Electrostatics, Current Electricity, and Magnetism appear in every paper without exception. Derivations account for 8–12 marks every year. Numericals from Optics and Modern Physics are perennial — the values change, the question structure doesn't.
Chemistry: Electrochemistry, Chemical Kinetics, and Coordination Compounds are consistently high-weight. In Organic Chemistry, name reactions and mechanism questions follow patterns that repeat across years. Biology: Chapter-level patterns are stable — Reproduction, Genetics, and Ecology together cover more than half the paper.
Maths: Calculus (Integration, Differential Equations) and Vectors/3D Geometry carry the most marks consistently. The internal choice pattern in Class 12 Maths rewards students who know which chapters to master deeply.
How to practise Class 12 PYQs — the correct method
The critical difference from how most students use PYQs: after solving each question, compare your answer to the official CBSE marking scheme — not just the answer key. The marking scheme shows which specific points earn marks, what CBSE's evaluators look for in a Physics derivation versus a stepwise numerical.
This matters more in Class 12 than Class 10 because the long-answer marking schemes are detailed. A 5-mark Physics derivation has 5 specific steps — each worth a mark. Knowing which steps are mandatory versus peripheral changes how you write answers.
Which years to prioritise for Class 12
Start with 2023, 2024, and 2025 — these reflect the current competency-based paper format with application-oriented questions and case-based sets in Science and Maths. Then work through 2019–2022 for the best balance of question variety and format relevance.
The 2015–2018 papers are useful for chapter-level pattern confirmation and for additional numerical and derivation practice — the question types remain valuable even if the overall format has shifted.

Frequently asked questions
Where can I get free CBSE Class 12 PYQ?
CBSE Class 12 previous year questions are available free on ClearSteps — all subjects, 2015 to 2025, with official marking schemes and AI pattern analysis. Individual papers are also on cbse.gov.in, though without the marking schemes bundled or the pattern read.
How many years of PYQ should I solve for Class 12?
Solve the most recent 3 years first — 2023, 2024, 2025 — as these reflect the current competency-based format. Then work through 2019–2022. Seven years of PYQ practice gives you comprehensive pattern exposure and format familiarity without diminishing returns.
Are CBSE Class 12 PYQ repeated in board exams?
Not verbatim, but structurally yes. Class 12 Physics derivations repeat the same derivations year after year — only the numerical values change. Chemistry name reactions follow the same question formats. Maths integration problems repeat question structures even when the specific functions differ. Knowing these patterns is a direct preparation advantage.
What is the difference between PYQ and sample paper for Class 12?
PYQs are actual past board exam papers from real exams (2015–2025). Sample papers are released by CBSE each October as guidance for the upcoming year's format and weightage. Both are essential: sample papers show this year's specific format and weightage; PYQs reveal what has been consistently tested over a decade.
Is solving PYQ enough for CBSE Class 12?
PYQs are the highest-leverage activity, but not sufficient alone. Cover NCERT first — PYQs tell you where to focus, not what to study. For Science, ensure all derivations and numericals are practised beyond just past papers. The combination: thorough NCERT, chapter-wise question practice, PYQs for format and pattern, and full timed papers in the final 6 weeks.
