Mathematics is one of the most feared — and yet most scoring — subjects in board examinations. Whether you are a Class 10 student facing your first major board exam or a Class 12 student preparing for a subject that can define your college future, the right preparation strategy makes all the difference. With the correct approach, consistent practice, and a well-structured study plan, scoring 90 or above in Maths is entirely achievable — for every student, not just the naturally gifted ones.
In this comprehensive guide, we break down a proven, board-focused preparation strategy for Class 10 and Class 12 Maths that covers everything from chapter-wise priorities to exam-day tips.
Why Maths Needs a Different Preparation Strategy
Unlike subjects where reading and memorisation are enough, Mathematics demands active problem-solving every single day. You cannot read Maths — you must do it. The board examination is structured to test three layers of learning: the ability to recall formulas and definitions, the ability to apply concepts to standard problems, and the ability to solve higher-order, multi-step questions.
There is one more critical fact that most students overlook: in a Maths board exam, marks are awarded for every correct step — not just the final answer. A student who writes the correct method but makes a calculation error at the last step can still earn 80–90% of the marks for that question. This means clear, step-by-step presentation is not optional — it is a scoring strategy in itself.
The Golden Rule: Always show your working. Every step you write is a mark you can earn.
Month-by-Month Study Plan: 3 to 4 Months Before Exams
A structured timeline prevents last-minute panic and ensures complete coverage of the syllabus. Here is a recommended month-by-month plan that works for both Class 10 and Class 12 students.
Month 1 — Complete the Syllabus
Your priority in the first month is to cover every chapter at least once. Do not skip chapters assuming they will not be asked — every unit contributes to your final score. Work through NCERT textbook exercises chapter by chapter. Do not worry about speed at this stage; focus on understanding concepts and methods thoroughly.
Month 2 — Revise and Strengthen Weak Areas
Once you have completed the syllabus, go back and revise. Pay extra attention to chapters where you made the most errors during Month 1. This is also the time to thoroughly solve all NCERT examples — not just the exercises. Research consistently shows that 60 to 70 percent of board exam questions are directly based on NCERT examples and exercises.
Month 3 — Previous Year Papers and Mock Tests
This is your exam simulation phase. Solve a minimum of five years of previous board exam papers under timed, exam-like conditions. This builds speed, improves accuracy, helps you understand the exam pattern, and shows you exactly where your preparation gaps are. Analyse every mistake you make and revisit those concepts immediately.
Final 2 Weeks — Revision and Formula Reinforcement
Do not try to learn anything new in the final two weeks. Focus entirely on revising formulas, key theorems, and methods you have already studied. Solve one or two papers per week to maintain momentum. Prepare a personal formula sheet for quick last-minute revision.
In the last three days before the exam, do light revision only. Go through your formula sheet, review the chapters where you feel least confident, and get adequate sleep. Rest is not a luxury before an exam — it is a performance tool.
Class 10 Maths Board Exam — Chapter-Wise Preparation Strategy
The Class 10 Maths paper is 80 marks (written) plus 20 marks for internal assessment. The written exam tests your understanding across six major units. Here is how to approach each one strategically.
Unit 1: Number Systems and Algebra (High Priority)
Real Numbers, Polynomials, Pair of Linear Equations in Two Variables, Quadratic Equations, and Arithmetic Progressions together form the largest portion of the paper. For Real Numbers, master Euclid's division algorithm and the fundamental theorem of arithmetic — questions from this chapter are almost always present. For Quadratic Equations, practice all three methods: factorisation, completing the square, and the quadratic formula. Word problems based on quadratic equations are a regular feature.
For Arithmetic Progressions, the nth term and sum formulas must be memorised perfectly. For Linear Equations, be comfortable with both the graphical method and algebraic methods, as word problems testing real-life applications are very common in board papers.
Unit 2: Coordinate Geometry and Geometry (High Priority)
Triangles is one of the most important chapters in Class 10. The Basic Proportionality Theorem (BPT), its converse, and the Pythagoras theorem are asked almost every year — often as proof-based questions worth 4 to 6 marks. Practice writing proofs step by step, as each logical step carries marks. Coordinate Geometry covers the distance formula, section formula, and area of a triangle using coordinates — these are formulaic and very scoring if practised regularly.
Unit 3: Introduction to Trigonometry and Applications
Trigonometric identities must be memorised perfectly. The most common question type asks students to prove a trigonometric identity, which is entirely dependent on knowing the standard identities and manipulating them step by step. Some Applications of Trigonometry — specifically Heights and Distances problems — use the angle of elevation and depression. These follow a standard pattern; practising 10 to 15 such problems is enough for confident scoring.
Unit 4: Mensuration — Surface Areas and Volumes
Questions on combinations of solids — such as a cone placed on top of a cylinder, or a hemisphere embedded in a sphere — are very commonly asked as 4 or 5 mark questions. Memorise all formulas and practice a variety of combination problems. This unit is highly predictable and very scoring.
Unit 5: Statistics and Probability (Very High Priority)
Statistics is one of the most reliable scoring areas in the entire paper. Mean, Median, and Mode from grouped data are asked almost every year, usually for 3 to 5 marks. Practice all three methods for calculating the mean: the Direct Method, Assumed Mean Method, and Step Deviation Method. Probability questions follow standard patterns and are straightforward once you understand the basic concepts.
Class 12 Maths Board Exam — Chapter-Wise Preparation Strategy
Class 12 Maths is significantly more abstract and concept-intensive than Class 10. The paper carries 80 marks (written) and 20 marks for internal assessment. Calculus alone accounts for approximately 35 marks — making it the single most important area of preparation.
Unit 1: Relations, Functions, and Inverse Trigonometric Functions
This unit covers types of relations, types of functions (one-one, onto, bijective), composition of functions, and inverse trigonometric functions with their principal values and properties. Questions are typically 1 to 2 marks each but are high in frequency. Clear your understanding of domain and range for inverse trig functions — errors here are very common and avoidable.
Unit 2: Matrices and Determinants (High Priority)
Matrix operations, properties of determinants, finding the inverse of a matrix using the adjoint method, and solving a system of linear equations using matrices are all high-frequency topics. Questions from this unit are structured and formulaic — with thorough practice, this unit can become one of your most reliable sources of marks. Pay special attention to properties of determinants and their applications in simplification.
Unit 3: Calculus — The Heart of Class 12 Maths (Highest Priority)
Calculus carries approximately 35 marks — the single largest share of the paper. It includes Continuity and Differentiability, Applications of Derivatives, Integrals, Applications of Integrals (Area under curves), and Differential Equations. This is where you must invest the most time.
For Differentiation, master the chain rule, product rule, quotient rule, and implicit differentiation. For Applications of Derivatives, focus on maxima and minima problems and rate of change questions. For Integration, practise all standard formulas and methods — substitution, integration by parts, and partial fractions — thoroughly. Definite integrals and area-under-curve questions are almost always present in the board paper.
For Differential Equations, focus on the variable separable method and linear differential equations of first order — these are the most commonly tested types. Solve every NCERT example in this unit without exception.
Unit 4: Vectors and Three-Dimensional Geometry (High Priority)
Vectors and 3D Geometry typically carry 10 to 14 marks combined. From Vectors, practise scalar (dot) product, vector (cross) product, and their geometric interpretations — angle between vectors, projection, area of parallelogram. From 3D Geometry, focus on equations of lines and planes in different forms, angle between lines and planes, and shortest distance between skew lines. This is a very predictable section with a fixed set of question types — regular practice makes it highly scoring.
Unit 5: Linear Programming and Probability
Linear Programming questions involve the graphical method and are structured and predictable — typically a 5-mark question. Probability in Class 12 covers conditional probability, Bayes' theorem, and probability distributions. Bayes' theorem is a favourite in board exams; practice a variety of standard problems. The Binomial Distribution is also commonly asked for 3 to 4 marks.
Time Management Strategy During the Exam
How you manage your time inside the examination hall is just as important as how well you have prepared. Follow this approach for maximum marks:
Use the first 10 to 15 minutes to read the entire question paper carefully. Do not start writing immediately.
Attempt questions you are most confident about first. This builds momentum and ensures you have already secured marks before tackling harder problems.
Allocate approximately 1 minute per mark as a rough guide. A 3-mark question should not take more than 3 to 4 minutes.
If you are stuck on a question, move on. Return to it at the end if time permits. Do not let one question consume time meant for three others.
Keep the last 5 to 10 minutes for review. Check for any steps you may have skipped, ensure units are correct, and verify that you have answered all parts of every question.
Write clearly and number your answers correctly. Untidy work and incorrect numbering create confusion for the examiner and can cost you marks.
Common Mistakes That Cost Students Marks
Awareness of common pitfalls is the first step to avoiding them. Here are the most frequent errors students make in Maths board exams:
Skipping NCERT examples and solving only the exercises. Examples are just as important — often more so.
Memorising formulas without understanding where they come from. Without understanding, one moment of exam stress can make a formula disappear from memory.
Not solving previous year papers in a timed setting. Reading through a paper is completely different from solving it under time pressure.
Poor presentation: not writing steps clearly, skipping intermediate steps, or using messy handwriting. Presentation is a scoring strategy.
Leaving chapters incomplete because they seem difficult. Every chapter contributes marks, and examinations often have questions from unexpected areas.
Spending too long on a single difficult question and running out of time for questions you could have answered easily.
Not cross-checking the final answer. A simple sign error or miscalculation in the last step can cost a fully solved question its full marks.
Best Resources for Maths Board Exam Preparation
The quality of your resources matters. Here are the most effective ones, in order of priority:
NCERT Textbook (Mandatory): Every example and every exercise must be solved. This is non-negotiable for both Class 10 and Class 12.
NCERT Exemplar Problems: Provides higher-difficulty problems based on the same syllabus. Excellent for students targeting 90+.
CBSE Official Sample Papers: Released by the board each year, these reflect the exact pattern, difficulty level, and marking scheme of the actual exam.
Previous Year Board Papers (Last 5 Years): The single most important practice resource after NCERT. Solve these under timed conditions.
R.D. Sharma or R.S. Aggarwal: For additional practice problems beyond NCERT, especially for algebra and calculus.
Video Lectures (YouTube / EdTech platforms): Excellent for clearing conceptual doubts, especially in Calculus and 3D Geometry for Class 12.
Important Note:
Quality consistently beats quantity. It is far more valuable to thoroughly solve and understand 5 years of previous board papers than to superficially attempt 10 different reference books.
Frequently Asked Questions
How many hours per day should I study Maths for board exams?
Ans : Aim for a minimum of 2 hours of focused, distraction-free Maths practice every day throughout your preparation period. In the final month, increase this to 3 to 4 hours, combining revision with timed paper-solving. Daily consistency is far more effective than marathon study sessions on weekends.
Is NCERT enough for Class 12 Maths board exams?
Ans: Yes, for the majority of students targeting 80 to 90 marks, NCERT — including all examples and miscellaneous exercises — is sufficient. For students aiming for 95 or above, supplement NCERT with the NCERT Exemplar and a selection of previous year papers. Never skip NCERT in favour of other books.
3. I am weak in Calculus for Class 12. Where do I start?
Ans: Begin from the very basics — Limits and Continuity — before moving to Derivatives and Integration. Watch video explanations for concepts you find confusing, then immediately solve NCERT examples on that topic. Do not rush through Calculus. Given that it carries 35 marks, spending extra time here has the highest return on investment of any unit in the entire syllabus.
4. How do I improve my speed in Maths during the exam?
Speed in Maths is built through repetition and familiarity. The more you practice solving a type of problem, the faster you become — because your brain stops treating it as a new challenge and begins to recognise the method instantly. Solve previous year papers strictly within the allotted time. Over several weeks of timed practice, your speed will improve naturally.
Should I complete the full syllabus first or start solving past papers?
Ans: Always complete the full syllabus before moving to intensive past paper practice. Skipping chapters to solve past papers leaves gaps in your knowledge that will hurt you when a question from an unexpected topic appears in the actual exam. Use Month 1 for syllabus coverage, Month 2 for revision and NCERT, and Month 3 for past papers.
Conclusion
Scoring 90 or above in your Class 10 or Class 12 Maths board examination is not a matter of talent — it is a matter of strategy, consistency, and smart effort. Start early, follow a structured plan, prioritise NCERT as your primary resource, practise previous year papers under real exam conditions, and present your solutions clearly and step by step.
Mathematics rewards students who show up every day. Build the habit of daily practice now, and your board exam score will reflect the effort you put in. Start today, stay consistent, and trust the process.
