My progress & mastery →Tuition charges every month for a schedule. Here is a free one, built around the NCERT book the board paper comes from.
- 15 min — read the next NCERT chapter (or the part your school covered today).
- 20–30 min — work the NCERT solution, then practise that chapter's important questions.
- 5 min — note any chapter that felt shaky to revisit at the weekend.
| Stage | Focus | Goal |
|---|---|---|
| Through the term | Each chapter: read → NCERT solution → important questions, the same week your school teaches it | No backlog — every taught chapter done |
| 1 month before exams | Revise chapter by chapter + memorise the formula sheets | Every chapter revised at least once |
| 2 weeks before | Solve previous-year papers under time | Comfortable with the pattern & timing |
| Final week | Re-practise only your weakest chapters + light formula revision | Calm, confident, no cramming |
Pick the timeline that fits you:
Through the year (steady)
After each chapter in school, do the NCERT solution + important questions the same week. By exam time you only revise — no last-minute panic.
Exam in a few weeks (catch-up)
Go chapter by chapter: solution → important questions → formulas. Then solve 3–5 previous-year papers under time and revise your weakest chapters.
How to turn NCERT mastery into full marks on the board paper.
Write the way the board marks
Answer in steps and points, not paragraphs. Show every step in maths and label diagrams in science — marks are given step by step.
Important questions repeat
Board papers reuse the same high-value questions year after year. Master the important-questions set and you have seen most of the paper before.
Previous-year papers are the best mock
Solve the last 3–5 years under time. They teach the pattern, the marking scheme and exactly where you lose marks.
Formulas must be automatic
Keep the formula sheet open while solving until the key formulas come without thinking — that saves precious exam minutes.
⏰ On exam day
- Use the 15-minute reading time to plan which questions to attempt first.
- Do the questions you know best first to bank marks and settle your nerves.
- Show all steps and underline final answers; attempt every question — there is no negative marking.
- Breathe. You learned it at your own pace; this is just one more practice paper.

Frequently asked questions
- Is NCERT enough to score well in CBSE?
- For most subjects, yes. CBSE board papers are based on NCERT, so mastering the textbook chapters, back-exercises and important questions covers the large majority of marks. Add previous-year papers to learn the pattern.
- How should I use NCERT solutions?
- Try each question yourself first, then check the step-by-step solution to fix mistakes. Don't just read — re-solve the ones you got wrong.
- Which classes are covered?
- Class 9 and 10 (Science and Maths) and Class 12 (Maths), with chapter-wise solutions, important questions, question papers and formula sheets. More are being added.
- Do I need coaching for CBSE?
- Not for most students. A steady habit of NCERT solutions, important questions and previous-year papers — all free here — is enough to score very well.
