Study Class 12 Chemistry alongside the papers
Why solve previous-year papers?
- See the real exam — the actual difficulty, phrasing and marking scheme, not a publisher's guess.
- Spot high-frequency chapters that repeat year after year, so you revise what matters most.
- Build exam-hall speed — full papers under a real timer expose where you lose minutes.
- Diagnose weak areas before the board exam, while there is still time to fix them.
How to use these papers
- 1Start chapter-wise early in the year — solve only the Chemistry questions from a chapter you have just finished.
- 2Switch to full timed papers 2–3 months before the exam: one complete set in the real time limit, no notes.
- 3Self-mark against the marking scheme, then fix every mistake with our free NCERT solutions.
- 4Re-attempt your weakest chapters until the recurring question types feel routine.
Before you practise older papers: some topics were removed from the rationalised CBSE syllabus in recent years. Skip any question on a deleted topic — it will not appear in your board exam.
