These chapters are consistently easy and predictable. Master them first:
| Chapter | Expected Marks | Effort Required |
|---|---|---|
| Ch 12 – Linear Programming | 5 marks | Low |
| Ch 2 – Inverse Trig | 4–5 marks | Low |
| Ch 3 – Matrices | 5 marks | Low |
| Ch 8 – Applications of Integrals | 5 marks | Low |
| Ch 1 – Relations & Functions | 3–4 marks | Low |
| Ch 13 – Probability (basic) | 5 marks | Medium |
| Ch 10 – Vectors (basic questions) | 4 marks | Medium |
✅ Total from above alone: ~35–40 marks — This is your safety net.
🚀 Step 2: Push to 70+
To go from 40 → 70+, target these:
- Ch 7 – Integrals: High marks chapter. Even if you solve 60% questions correctly, you gain 8–10 marks.
- Ch 5 – Continuity & Differentiability: Learn the 5 standard question types — scores 5–6 marks.
- Ch 6 – Applications of Derivatives: Maxima/Minima problems have fixed patterns — learn the steps.
- Ch 11 – 3D Geometry: Line and plane problems follow a fixed format — memorize the approach.
- Ch 4 – Determinants: The 5-mark matrix inverse question is almost always asked.

PRIORITY 3 (Attempt if Time Allows):
→ Ch 1, Ch 2, Ch 3, Ch 9
📆 What to Revise Daily
| Task | Time |
|---|---|
| Formula sheet revision | 20 mins every morning |
| Solve 3–5 PYQs from weak chapter | 30 mins every evening |
| Re-attempt yesterday's wrong questions | 15 mins |
| Read NCERT examples once | 20 mins |
🏁 Last Day Revision Strategy
Do this on the day before the exam:
- ✅ Read your handwritten formula sheet — do NOT read new topics
- ✅ Solve 10–15 1-mark and 2-mark MCQ type questions only
- ✅ Revise: LP graphical method steps, Bayes theorem template, Integration by parts steps
- ✅ Check: Standard integral formulas, Determinant properties, 3D Geometry distance formulas
- ✅ Sleep at least 7–8 hours
- ✅ Keep your admit card, stationery, geometry box ready
- ✅ Eat light, stay hydrated, stay calm
💡 Board Writing Tips
- Always write steps clearly, even in 1-mark questions if it's subjective
- Box your final answer
- Draw diagrams for AOD, 3D, LP — they fetch bonus impression marks
- Attempt all questions — partial marks are given for correct method
- Manage time: Section A (MCQ) → 20 min, Section B → 25 min, Section C+D → 65 min, Section E → 30 min
💪 YOU ARE READY. TRUST YOUR PREPARATION. WRITE CLEARLY. SCORE BIG. 🎯 Hard work + Smart Revision = 70+ in CBSE Maths. You've got this!
