Section-wise Breakdown:
- Section A: 20 MCQs (1 mark each) = 20 marks
- Section B: 5 Short Answer Questions (2 marks each) = 10 marks
- Section C: 6 Short Answer Questions (3 marks each) = 18 marks
- Section D: 4 Long Answer Questions (5 marks each) = 20 marks
- Section E: 3 Case Study Questions (4 marks each) = 12 marks

Mathematics Preparation Strategy
Step 1: Master NCERT (2-3 months before exams)
Critical: NCERT is the foundation. 40-50% questions are directly from NCERT.
- Solve every example in each chapter
- Complete all exercise questions (including optional exercises)
- Focus on solved examples - They often appear in exams with slight modifications
- Memorize all formulas, identities, and theorems
Step 2: Create a Formula Sheet (Ongoing)
Compile all formulas in one place:
Algebra:
- (a+b)² = a² + 2ab + b²
- (a-b)² = a² - 2ab + b²
- a² - b² = (a+b)(a-b)
- Quadratic formula: x = (-b ± √(b²-4ac)) / 2a
Trigonometry:
- sin²θ + cos²θ = 1
- 1 + tan²θ = sec²θ
- 1 + cot²θ = cosec²θ
Coordinate Geometry:
- Distance = √[(x₂-x₁)² + (y₂-y₁)²]
- Midpoint = ((x₁+x₂)/2, (y₁+y₂)/2)
- Area of triangle = ½|x₁(y₂-y₃) + x₂(y₃-y₁) + x₃(y₁-y₂)|
Revise this sheet daily in the final month.
Step 3: Practice Sample Papers (1 month before)
- Solve 15-20 sample papers
- Time yourself: 3 hours strictly
- Focus on case study questions - They're new and tricky
- Check step-by-step marking from marking scheme
Step 4: Focus on Common Mistakes
Mistake 1: Not writing formulas
❌ Directly substituting values
✅ First write formula, then substitute
Mistake 2: Missing units
Always write units in final answer (cm, m², cm³, etc.)
Mistake 3: Skipping steps
Even if you know the answer, write step-by-step solution for full marks
Mistake 4: Poor diagram labeling
In geometry, draw diagrams neatly and label all points clearly
Time Management in Math Exam
