CBSE Class 10 maths: how to prepare, week by week

Maths in the Class 10 board exam rewards steady practice and clear steps, not last-minute cramming. This plan assumes about three months before the exam and 60 to 90 minutes of maths on most days. Adjust it if you have more or less time.

Important: CBSE updates its curriculum, marking scheme and sample papers from time to time. Always check the current curriculum document and sample papers on the official CBSE website and follow your school's guidance. This guide teaches a method. It does not replace the official syllabus.

Standard or Basic?

CBSE offers two Class 10 maths papers, Mathematics Standard and Mathematics Basic. Standard is meant for students who may study maths further; Basic is a lighter paper. Eligibility and rules for choosing and later changing can change, so discuss this with your school and read CBSE's current notice before deciding.

The topics, grouped

Class 10 maths ideas fall into these groups. Check the official curriculum for exact chapters and weightage.

• Number systems and algebra: real numbers, polynomials, pair of linear equations, quadratic equations, arithmetic progressions.
• Coordinate geometry: distance and section formulas and areas.
• Geometry: similar triangles and circles (tangents).
• Trigonometry: ratios, identities, heights and distances.
• Mensuration: areas related to circles, surface areas and volumes.
• Statistics and probability: mean, median and mode of grouped data, and probability.

A 12-week plan

Weeks 1 to 2: Real numbers, polynomials, linear equations. Revise concepts and solve every textbook example and exercise question. Start your mistake notebook and one-page formula sheet.

Weeks 3 to 4: Quadratic equations and arithmetic progressions. Practise both factorisation and the formula. Check every answer by substituting back. Our quadratic equation solver shows the steps so you can check your working.

Weeks 5 to 6: Triangles, coordinate geometry, circles. Learn proofs step by step: Given, To prove, Proof, reasons. Draw a neat figure every time.

Weeks 7 to 8: Trigonometry and applications. Learn the ratios and identities, then do heights and distances with a clear figure. Use the Pythagoras calculator and the scientific calculator to check values (calculators are usually not allowed in the board exam, so use them only for practice).

Weeks 9 to 10: Mensuration, statistics, probability. Understand where each formula comes from. Practise combined-solid and grouped-data questions.

Weeks 11 to 12: Full papers. Solve official sample papers and previous papers under exam timing, then analyse mistakes by type: concept gap, calculation slip, misreading, time lost.

The daily routine

1. 10 minutes: revise yesterday's mistakes.
2. 40 to 60 minutes: new questions on one topic, written on paper with steps.
3. 10 minutes: check answers and update the mistake notebook.

How to use sample papers

• Do the first one open-book if needed, to learn the style.
• Do the next ones in strict time, in one sitting.
• After each paper, sort every lost mark into: didn't know, calculation slip, misread, ran out of time, and fix the biggest group.

Common mistakes in the board exam

• Skipping steps and losing method marks.
• Not drawing a figure for geometry and trigonometry questions.
• Copying the question numbers wrongly.
• Spending too long on one hard question. Move on and return.
• Not reading the whole question, especially case-study questions.

Exam-day tips

• Read the whole paper in the reading time and mark the questions you are sure of.
• Start with the sections you are most confident about to build momentum.
• Write neatly with clear steps and a boxed final answer.
• Leave a few minutes to check calculations.

When to get extra help

If a topic does not improve after a week of practice, get help early rather than leaving it for the last weeks. Our Class 10 maths page and maths exam preparation classes start from the topics you share. A student or parent can send the board, textbook and exam date, and we will plan the weeks that remain. We cannot promise marks, but we can help you prepare in an organised way.

Common questions

How many hours should I study for Class 10 maths?

Most students do well with 60 to 90 focused minutes on most days, more in the last month. Consistency beats occasional long sessions.

Is NCERT enough for CBSE Class 10 maths?

Your NCERT textbook is the base: solve all examples and exercises. Then add sample papers and practice from your school so you meet different question styles.

How do I get full marks in geometry proofs?

Write a clear figure, state what is given and what is to be proved, then give each step with its reason. Practise a few proofs every week.

Are calculators allowed in the CBSE maths exam?

Calculators are generally not allowed in the board exam, so practise without them. Check the current CBSE exam instructions.

What if I am weak in algebra?

Start with the foundation (linear equations, factorisation) and practise daily. Our guides on learning maths easily and preparing for maths exams can help.

This guide is general information. For exams, follow your school, teacher and official exam board, and use your own judgement about what suits your child.
