Teachers and exam analysts advise that focused revision of the following chapters from the NCERT Class 10 Mathematics syllabus will help students cover the most likely scoring areas:

Real Numbers

Euclid’s Division Lemma
Fundamental Theorem of Arithmetic
Problems involving HCF and LCM

Polynomials

Zeros of a polynomial
Relationship between zeros and coefficients
Graphical representation of polynomials

Pair of Linear Equations in Two Variables

Solutions by graphical and algebraic methods
Application-based word problems

Quadratic Equations

Methods of solving: factorisation and completing the square
Nature of roots

Arithmetic Progressions (AP)

Finding the nth term

These topics are central to the board exam pattern and often form the backbone of both objective and subjective questions in the Mathematics paper.

How to Strengthen Preparation Before the Exam?

Beyond knowing the important chapters, students should also:

Solve previous years’ board papers to familiarise with question style.
Practise sample papers and model questions that reflect the expected pattern.
Focus on solving diverse problem types and applications from NCERT exercises.
Work on time management to complete the Mathematics paper within the allotted exam duration.

Exam Day Tips (Mathematics)

On the day of the 17 February exam, students should:

Start with questions they find conceptually clear to build confidence.
Show steps clearly, especially for multi-step problems.
Check the answer sheet for simple arithmetic mistakes before submission.

Targeted revision of these high-impact topics, combined with consistent practice and exam-day strategy, can significantly improve overall performance in the CBSE Class 10 Mathematics exam 2026.
