The Council for the Indian School Certificate Examinations (CISCE) has prescribed the ISC Class 11 Mathematics syllabus for the 2026-27 academic session. The syllabus is designed to help students understand mathematical concepts, improve problem-solving skills and develop logical thinking. It covers different topics, including algebra, geometry, trigonometry, calculus and statistics.
Mathematics is an important subject for students planning to pursue higher studies in engineering, physics, chemistry, architecture and other related fields. The Class 11 syllabus builds the foundation for more advanced mathematical concepts that students will study in Class 12.
The ISC Class 11 Mathematics syllabus 2026-27 is divided into five major units. Students should understand all the topics included in these units before starting their examination preparation.

ISC Class 11 Mathematics Complete Syllabus: Unit-Wise Topics
The syllabus covers five major units. Each unit includes different chapters and concepts that students need to study during the academic year.
1. Sets and Functions
This unit introduces students to sets, relations, functions and trigonometry. Students will learn how to group numbers and objects, understand relationships between different sets and study how one quantity depends on another.
| Core Chapter | Important Topics |
|---|---|
| Sets | Sets and their representationEmpty, finite, and infinite setsEqual sets, subsets, and power setsUniversal sets and Venn diagramsUnion, intersection, and complement of sets |
| Relations & Functions | Relations and functionsDomain, range, and co-domainDifferent types of functions |
| Trigonometric Functions | Trigonometric functions and identitiesPositive and negative anglesAngles measured in degrees and radiansGraphs of trigonometric functionsCompound and multiple-angle formulas |
2. Algebra
Algebra is the highest-weightage unit, carrying 26 marks in the theory paper. It includes different mathematical concepts that help students solve equations, understand number patterns and calculate different possibilities.
The topics covered are:
| Core Chapter | Key Topics |
|---|---|
| Complex Numbers & Quadratic Equations | Complex numbers and their properties Argand plane and polar representation Quadratic equations and quadratic functions Nature of roots |
| Inequalities | Linear and quadratic inequalities |
| Permutations & Combinations | Permutations and combinations Factorials and the fundamental principle of counting |
| Binomial Theorem | Binomial theorem and Pascal's triangle |
| Sequences & Series | Sequences and series Arithmetic Progression (AP) and Geometric Progression (GP) Arithmetic Mean (AM) and Geometric Mean (GM) Sum of special series |
3. Coordinate Geometry
Coordinate Geometry carries 20 marks. This unit teaches students how to understand and represent different shapes and lines using numbers and graphs. It also introduces the basic concepts of three-dimensional geometry.
| Core Chapter | Important Topics |
|---|---|
| Straight Lines | Straight lines and their slopes Different forms of equations of a straight line Distance between points and lines |
| Circles | Circles and their equations Centre and radius of a circle |
| Conic Sections | Conic sections Parabola, ellipse, and hyperbola Focus, directrix, and latus rectum |
| Three-Dimensional Geometry | Introduction to three-dimensional geometry Coordinates of points in three dimensions Distance and section formulas |
4. Calculus
Calculus carries 8 marks in the theory examination. It introduces students to limits and derivatives. These concepts help explain how quantities change and how the slope of a curve can be calculated.
| Core Chapter | Important Topics |
|---|---|
| Limits | Introduction to limits Left-hand and right-hand limits Limits of algebraic, trigonometric, exponential and logarithmic functions |
| Derivatives | Meaning and definition of derivatives Geometrical meaning of derivatives Differentiation using first principles Derivatives of sums, differences, products and quotients of functions (Rules of Differentiation) |
5. Statistics and Probability
This unit carries 8 marks and focuses on collecting, understanding and analysing numerical information. Students also learn how to calculate the chances of different events.
The topics include:
| Core Chapter | Important Topics |
|---|---|
| Statistics (Measures of Dispersion) | Measures of dispersion Range and mean deviation Variance and standard deviation Grouped and ungrouped data Combined mean and standard deviation |
| Probability | Random experiments and their outcomes Sample space and events Sure and impossible events Mutually exclusive and exhaustive events Probability of an event Addition theorem of probability |
ISC Class 11 Mathematics Exam Pattern 2026-27
According to CISCE, the Mathematics examination has two papers. The first is the theory examination, while the second is project work.
| Paper | Assessment Type & Duration | Marks Allotted |
|---|---|---|
| Paper I | Theory Examination (3 Hours) | 80 |
| Paper II | Internal Project Work | 20 |
| Total | 100 |
For project work, students are required to complete two projects. Each project carries 10 marks. The marks for each project are divided into four parts: overall format (1 mark), content (4 marks), findings (2 marks) and viva-voce (3 marks).

Preparation Tips for ISC Class 11 Mathematics
Students should begin their preparation by understanding the syllabus and identifying the topics included in each unit. They should practise mathematical problems regularly instead of only reading formulas. Algebra and Coordinate Geometry carry a combined weightage of 46 marks, so students should give sufficient attention to these units.
It is also important to revise formulas, solve practice questions and understand the basic concepts before attempting difficult problems. Students should complete both projects on time and prepare for the viva-voce. Following the official syllabus will help students avoid studying unnecessary topics and plan their preparation in a better way.
