ICSE Class 10 Maths Syllabus 2025-26: Latest Changes & Chapter-Wise Weightage

The ICSE Class 10 Maths Syllabus 2025-26 was published by the Council of the Indian School Certificate Examinations (CISCE), and it is a mixture of continuity and subtle change. The first step to successful preparation is understanding the syllabus. This comprehensive guide will assist you in planning your study better, whether you are plotting your study timetable, working out the previous year's question papers of ICSE Class 10 or revising with your maths book of ICSE Class 10.

The Importance of the Latest Syllabus

ICSE mathematics is a scoring subject as long as you have clarity of concepts and good problem-solving ability. The syllabus provides a logical route to follow, and being aware of the most recent updates means that you are not revising out-of-date or irrelevant material. The exam is application-oriented, which is why it is necessary to have the correct approach and focus on weighted chapters.

So, now, we shall have a look at what the ICSE Class 10 Mathematics syllabus 2025-26 will be.

ICSE Class 10 Mathematics Syllabus 2025-26: Complete Overview

The syllabus is broadly categorized into the following units:

1. Commercial Mathematics

2. Algebra

3. Geometry

4. Mensuration

5. Trigonometry

6. Statistics and Probability

Each of these units is further broken into chapters, with varying weightage in the final board exam.

What are the Latest Changes in ICSE Class 10 Maths Syllabus 2025-26?

The 2025-26 syllabus has kept the main outline but made some slight changes:

• More attention paid to application-based questions

• Focus on Commercial Maths as applied to real-life problems

• Sub-topics in Algebra and Geometry are refined to minimize redundancy

• Probability and Statistics have gained a little more importance in the analysis-based questions

In the case of students preparing for 10 years of ICSE Class 10 solved papers, these changes may not cause a drastic change in the preparation pattern, but awareness is the most important factor in not getting a surprise during the final examination.

Chapter-Wise Weightage: What Should You Focus On?

Each chapter carries a different weight in the board exams. Here's a table showing an approximate distribution based on previous trends and paper analysis:

Expected Chapter-Wise Weightage

These are approximate values and may vary slightly, but they help prioritize your revision schedule using your ICSE books.

Which Chapters Are Most Scoring in ICSE Class 10 Maths?

Algebra is the most scoring unit, and is closely followed by Geometry and Trigonometry. These chapters are frequently repeated in the previous years' question papers of ICSE Class 10, and many times their pattern is repetitive. Knowing these subjects well puts you in a high probability of scoring full marks in such subjects.

Easier but requiring precision and formula answers are Mensuration and Commercial Mathematics. You should learn to diagram and apply formulae with your ICSE Class 10 maths book.

How Should I Start My Preparation for ICSE Maths?

Begin by identifying high-weightage chapters. For example, start with:

• Quadratic Equations

• Trigonometry

• Coordinate Geometry

• Statistics

Then gradually move to medium-weight chapters like:

• Mensuration

• Commercial Mathematics

• Constructions

The keys are consistency, clarity of concept, and practice. Track the type of questions that are frequently occurring by using the 10-year ICSE Class 10 solved papers.

What is the number of chapters in ICSE Class 10 Mathematics 2025-26?

The book contains about 15 main chapters that are subdivided into 6 major units. These comprise GST, Shares, Quadratic Equations, Trigonometry, Statistics, and so on. Both conceptual knowledge and speed and accuracy are needed in each chapter.

What is the best strategy to finish the ICSE Class 10 Maths syllabus on time?

• Break your schedule into weekly targets

• Use your maths book for ICSE Class 10 to finish core concepts first

• Allocate 2-3 hours weekly to revision and problem-solving

• In the final 2 months, solve 2-3 ICSE Class 10 previous years' question papers every week

• Revisit difficult chapters using your classroom notes and examples from your ICSE books

Which chapters from Algebra should I give maximum time to?

Algebra includes several sub-topics, like:

• Quadratic Equations

• Linear Inequations

• Matrices

• Factorisation

The first ones you need to focus on are Quadratic Equations and Simultaneous Linear Equations because they are weighty and they often come as previous years' question papers in ICSE Class 10.

Are there any deleted topics or reduced chapters this year?

No significant deletions were made as per the official update of 2025-26. But some sub-topics could have been narrowed down or combined. Always use the latest circular of CISCE and compare it with your ICSE books to cross-check the coverage of content.

How important is Trigonometry, and how should I prepare for it?

Trigonometry accounts for roughly 15 marks and includes identities, heights, and distances. This chapter is visual and conceptual, so you must:

• Practice daily using formulae

• Draw accurate diagrams

• Solve real-life application questions

Use 10 years ICSE Class 10 solved papers to understand past question trends and practice time management.
