Quick Answer: Score 90+ in Maths by mastering NCERT, revising formulas daily, practicing step-by-step solutions, solving previous year papers, and maintaining a mistake notebook for continuous improvement.

Scoring 90+ in Maths in Class 10 and Class 12 is possible for most students if they follow the right strategy. Maths is not a subject where marks improve only by reading. It improves through concept clarity, formula revision, step-by-step practice, mistake analysis, and timed mock tests.

Many students work hard but do not score well because they repeat the same mistakes: they skip NCERT examples, memorize formulas without understanding, avoid weak chapters, and start sample papers too late. A smarter approach is to build a clear chapter-wise plan and revise regularly.

This guide explains how to score 90+ in Maths in Class 10 and 12 with practical steps, daily routine, revision strategy, exam-writing tips, and a final checklist for students and parents.

Students who consistently score above 90 do not study randomly. They follow a structured cycle: concept → practice → mistake analysis → revision. This loop ensures that weaknesses are corrected early and confidence builds gradually before exams.

If your main difficulty is solving problems step-by-step, also read How to Improve Maths Problem Solving for Class 10, 11 and 12. If calculation speed is weak, use Vedic Maths Techniques for Faster Calculation as a supporting speed-building guide.

Why 90+ in Maths Needs Strategy

Maths is a scoring subject because answers are objective and step-based. If your concept is clear and your steps are correct, you can score high marks. But Maths also punishes small errors such as sign mistakes, formula mistakes, skipped steps, wrong units, and poor time management.
  • Concept clarity helps solve new questions.
  • Formula memory saves time.
  • Step-wise writing helps earn partial marks.
  • Regular practice improves speed.
  • Mistake analysis reduces repeated errors.
  • Timed papers improve exam confidence.
  • Neat presentation improves answer readability.

Step 1: Understand the Syllabus and Weightage

Before starting preparation, understand the complete syllabus. Many students study randomly and later realize that some high-weightage chapters were ignored. Make a list of chapters and divide them into strong, medium, and weak categories.
  • Write all chapters in one notebook page.
  • Mark high-weightage chapters.
  • Identify weak chapters honestly.
  • Check school exam pattern or board pattern.
  • Plan revision based on priority.
  • Do not ignore easy scoring chapters.
Class 10 students should pay attention to algebra, geometry, trigonometry, coordinate geometry, statistics, and probability. Class 12 students should carefully plan calculus, matrices, determinants, vectors, 3D geometry, probability, and differential equations.

Step 2: Master NCERT First

NCERT should be completed first for both Class 10 and Class 12. Many students jump to extra books without mastering NCERT examples and exercises. This creates confusion and weak confidence.
  • Read the theory before examples.
  • Solve all solved examples.
  • Complete all exercise questions.
  • Re-solve difficult NCERT problems.
  • Mark important and repeated patterns.
  • Do not skip miscellaneous exercises in Class 12.
NCERT gives the foundation. After NCERT, sample papers and previous-year questions help you improve exam readiness.

Step 3: Make Chapter-Wise Formula Notes

Formula notes are extremely important for scoring 90+. Do not keep formulas scattered across textbooks. Create a separate formula notebook or quick revision sheet.

  • Write formulas chapter-wise.
  • Add meaning of each symbol.
  • Write conditions where formula is used.
  • Add one example for difficult formulas.
  • Mark identities and theorems separately.
  • Revise formula notebook daily.

For trigonometry, calculus, coordinate geometry, vectors, probability, and matrices, formula revision should be frequent. Small formula mistakes can reduce marks even when the method is correct.

Step 4: Practice Step-by-Step Solutions

Board exams value step-wise solutions. Even if the final answer is wrong, correct steps may earn marks. So do not solve only mentally. Practice writing full solutions.

  • Write given data clearly.
  • Write formula or theorem used.
  • Show substitution step.
  • Do calculation neatly.
  • Do not skip important transformations.
  • Box or underline the final answer.
  • Check signs and units.

Step writing is especially important in proofs, geometry, trigonometry, calculus, probability, and word problems.

Step 5: Build Speed with Timed Practice

Many students know the answers but lose marks because they cannot finish the paper on time. Speed improves only through timed practice.

  • Solve 10 questions within a fixed time.
  • Practice one section at a time.
  • Use a timer for sample papers.
  • Do not spend too long on one question.
  • Learn to move forward and return later.
  • Practice writing neatly but quickly.

Speed should not come at the cost of accuracy. First build accuracy, then improve speed.

Step 6: Use Previous Year Papers and Sample Papers

Previous year papers help students understand question style, important chapters, and repeated patterns. Sample papers help with full exam practice.

  • Solve at least 5 previous year papers.
  • Solve sample papers in exam-like conditions.
  • Check answers honestly.
  • Mark questions that took too much time.
  • Revise weak chapters based on paper analysis.
  • Repeat wrong questions after a few days.

Do not just read solutions. Solve papers by writing full answers.

Step 7: Maintain a Mistake Notebook

A mistake notebook is one of the fastest ways to improve Maths marks. Every student makes mistakes, but high-scoring students do not repeat the same mistake again and again.

  • Formula mistake.
  • Sign mistake.
  • Calculation mistake.
  • Concept mistake.
  • Step skipping.
  • Wrong diagram.
  • Time management mistake.

Before exams, revise the mistake notebook. It is your personal improvement guide.

Class 10 Maths Strategy

Class 10 Maths requires strong NCERT practice, formula clarity, and neat step-writing. Students should focus on both problem-solving and presentation.
  • Polynomials: understand zeroes and coefficient relations.
  • Pair of Linear Equations: practice all solution methods.
  • Quadratic Equations: master factorization and formula method.
  • Arithmetic Progressions: revise nth term and sum formulas.
  • Coordinate Geometry: avoid distance and section formula mistakes.
  • Trigonometry: memorize identities with meaning.
  • Circles: write theorem-based steps clearly.
  • Areas and Volumes: revise formulas daily.
  • Statistics and Probability: practice calculation carefully.

Class 12 Maths Strategy

Class 12 Maths needs consistent practice because chapters are interconnected. Calculus is very important, but students should not ignore matrices, determinants, vectors, 3D geometry, probability, and linear programming.
  • Relations and Functions: understand types and composition.
  • Inverse Trigonometry: revise domains and ranges.
  • Matrices and Determinants: practice operations and properties.
  • Continuity and Differentiability: master standard derivatives.

Best Next Step Based on Student Level

Every student does not need the same type of support. A student scoring 35–50% usually needs concept rebuilding and basic practice. A student scoring 60–75% usually needs chapter-wise revision, formula clarity and more written practice. A student already near 80% usually needs sample papers, time management and mistake reduction.

  • Below 50%: Focus on basics, NCERT examples, formula meaning and guided problem-solving.
  • 50–70%: Complete NCERT, revise formulas weekly, solve chapter tests and maintain a mistake notebook.
  • 70–85%: Practice previous-year papers, improve speed and revise weak chapters.
  • 85%+: Target presentation, time management, advanced mixed questions and final polishing.

This approach helps students and parents choose a realistic study plan instead of copying another student’s routine.
