How to Score 90+ in CBSE 10th Mathematics: NCERT-Based Preparation Strategy

CBSE Class 10 Mathematics is a subject where students can score full marks with the right approach. The key is thorough NCERT understanding and strategic practice. Here is how to achieve 90+ scores.

Why NCERT is the Foundation

1. CBSE Exam Pattern

The CBSE Class 10 Mathematics question paper follows a strict pattern based on NCERT:

• Section A: 20 marks, 10 questions of 1 mark each (very short answer)
• Section B: 12 marks, 4 questions of 2 marks each (short answer)
• Section C: 28 marks, 6 questions of 4 marks each (long answer I)
• Section D: 20 marks, 4 questions of 5 marks each (long answer II)
• Total: 80 marks, 30 questions in 3 hours

Most 1-mark and 2-mark questions are direct NCERT exercises. 4-mark and 5-mark questions require application of concepts.

2. Chapter-Wise Weightage (CBSE 2026)

Chapter	Marks	Focus Areas
Number Systems	3-4	Irrational numbers, real numbers
Algebra (Polynomials, Pair of Linear Equations, Quadratic Equations, Arithmetic Progression)	20-22	Most important area
Geometry (Triangles, Circles, Constructions)	15-16	Proofs and constructions
Trigonometry (Introduction, Heights and Distances)	12-13	Application-based questions
Coordinate Geometry	7-8	Formula-based
Mensuration (Areas and Volumes)	10-12	Formula application
Statistics and Probability	10-11	Mean, median, mode, basic probability

3. Preparation Strategy

Phase 1: Concept Building (April to July)

• Complete NCERT textbook exercises for each chapter
• Understand each theorem and proof - don’t just memorise
• Solve every example in NCERT before moving to exercises
• Make chapter notes with formulas and key points

Phase 2: Intensive Practice (August to October)

• Solve NCERT Exemplar problems (higher-order thinking questions)
• Practice previous 5 years’ CBSE sample papers
• Focus on 4-mark and 5-mark questions - they carry most weightage
• Time yourself while solving each paper

Phase 3: Final Polishing (November to February)

• Revise formula sheets daily (create one page per chapter)
• Solve sample papers under exam conditions (3 hours)
• Focus on weak areas identified through practice
• Memorize common formulas for Mensuration and Trigonometry

4. Chapter-Specific Tips

Algebra (Most Important - 20+ marks)

• Polynomials: Understand zeroes and coefficients relationship
• Pair of Linear Equations: Graphical method, algebraic method, elimination method
• Quadratic Equations: Factorisation, formula method, nature of roots
• Arithmetic Progression: nth term, sum of n terms, word problems

Geometry (15-16 marks)

• Triangles: Similarity criteria, Pythagoras theorem, area ratios
• Circles: Tangent properties, chord properties, cyclic quadrilaterals
• Constructions: Division of segment, tangent from external point, triangle construction
• Trigonometry: Trigonometric ratios, identities, heights and distances problems

Trigonometry (12-13 marks)

• Memorize values: sin, cos, cot, cosec, sec for 0°, 30°, 45°, 60°, 90°
• Master identities: sin²θ + cos²θ = 1, 1 + tan²θ = sec²θ, 1 + cot²θ = cosec²θ
• Heights and distances: One story problem usually comes; practise 2-3 variations

Coordinate Geometry (7-8 marks)

• Distance formula: d = √((xâ‚‚-x₁)² + (yâ‚‚-y₁)²)
• Section formula: Internal and external division
• Area of triangle: Using coordinates
• Slope of line: Parallel and perpendicular conditions

Mensuration (10-12 marks)

• Area and perimeter: Circle, sector, segment, triangle, quadrilateral
• Surface area and volume: Cube, cuboid, cylinder, cone, sphere, hemisphere
• Key formulas: Memorise all - they’re direct marks

Statistics and Probability (10-11 marks)

• Mean, median, mode: Using direct method, assumed method, step-deviation method
• Probability: Basic problems with coins, dice, cards
• Graphical representation: Ogives, histograms (theory-based questions)

5. Common Mistakes to Avoid

• Not showing steps: CBSE awards marks for method, not just the final answer
• Calculation errors: Double-check arithmetic, especially in word problems
• Formula errors: Write formula before substituting values
• Skipping units: Mention units (cm, cm², etc.) in final answer
• Messy diagrams: Use pencil and ruler for Geometry constructions
• Leaving questions blank: Attempt every question - even partial attempt gets marks

6. Day Before Exam

• Revise formula sheets only - don’t start new topics
• Sleep early - mathematics requires a fresh mind
• Keep sharp pencil, eraser, ruler ready
• Write question paper number correctly on answer book

7. Exam Day Strategy

• First 15 minutes: Read all 30 questions, mark which you’ll attempt first
• Attempt 5-mark questions first - they carry most weightage and require fresh mind
• Keep 15 minutes at end for review and attempting left questions
• Check all calculations before submitting
• Neatly label all diagrams and graphs

How Scholar Academy Helps

Our CBSE Mathematics batches follow a structured approach:

• Concept building phase: April to July (complete NCERT thoroughly)
• Intensive practice phase: August to October (Exemplar + sample papers)
• Exam simulation phase: November to February (weekly timed tests)
• Individual attention: Batch size limited to 35 students
• 2 teachers per subject: One for concepts, one for practice

Our students receive:

• Chapter-wise worksheets with focused practice
• Weekly tests with detailed solution analysis
• Formula sheets for quick revision
• Individual doubt-clearing sessions
• Progress tracking and parent reports

Start early, stay consistent, and practise NCERT extensively. Mathematics rewards discipline more than any other subject.
