Sub-Units Under ISC Class 12 Mathematics Chapters
The ISC Class 12 Mathematics syllabus is designed to strengthen analytical ability and mathematical reasoning. Below is a clear overview of each unit included in the syllabus.
Relations and Functions (10 Marks)
This unit builds the foundation for understanding mathematical relationships between variables.
- Relations
Students learn about different types of relations such as reflexive, symmetric, transitive and equivalence relations. Problems often involve identifying and proving properties of relations.
- Functions
This chapter focuses on domain, range, types of functions and composition of functions. Students also study inverse functions and one-one and onto mappings.
You should strengthen these concepts because they are used frequently in Calculus and higher mathematics.
Algebra (10 Marks)
The Algebra unit focuses on systems of equations and matrix operations.
- Matrices
Students learn matrix operations such as addition, multiplication and transpose. Applications include solving linear equations using matrices.
- Determinants
This chapter includes evaluating determinants, properties of determinants and solving systems of linear equations using Cramer’s Rule.
Determinants are also useful in coordinate geometry and vector algebra problems.
Calculus (35 Marks)
Calculus is the largest and most important section of the ISC Class 12 Mathematics syllabus.
- Continuity and Differentiability
Students learn limits, continuity of functions and differentiation techniques. These concepts form the basis of advanced calculus.
- Application of Derivatives
This chapter explains how derivatives are used to determine:
- Increasing and decreasing functions
- Local maxima and minima
- Rate of change problems
- Tangents and normals
These questions are commonly asked in board examinations.
- Integrals
Integration is the reverse process of differentiation. Students learn standard integration formulas and techniques of substitution.
- Application of Integrals
This section focuses on finding area under curves and area between curves using definite integrals.
- Differential Equations
Students learn to form and solve simple differential equations. These equations are used to model real-life phenomena like population growth and decay.
Since Calculus carries the highest weightage, regular practice is essential to score well.
Vector Algebra (5 Marks)
Vector Algebra introduces students to vectors in mathematical space.
Key topics include:
- Vector representation
- Dot product and cross product
- Area of parallelogram and triangle using vectors
Vectors are extremely important for students planning to study physics, engineering, or computer science.
Three-Dimensional Geometry (6 Marks)
Three-dimensional geometry extends coordinate geometry into 3D space.
Students learn concepts such as:
- Direction ratios and direction cosines
- Equation of a line in space
- Shortest distance between two lines
- Distance of a point from a plane
Questions in this unit test visualization and spatial reasoning skills.
Linear Programming (5 Marks)
Linear Programming Problems (LPP) focus on optimization.
Students learn to:
- Form linear equations based on real-life situations
- Draw feasible regions on graphs
- Determine maximum or minimum values of functions
These concepts are widely used in economics, business management and operations research.
Probability (9 Marks)
Probability in ISC Class 12 Maths syllabus focuses on advanced probability concepts.
Important topics include:
- Conditional probability
- Multiplication theorem of probability
- Bayes’ theorem
- Random variables
- Probability distributions
Probability questions are usually conceptual and require clear understanding of formulas.
ISC Class 12 Mathematics Project Work (20 Marks)
Project work is an important part of the Mathematics syllabus.
Students must complete two mathematical projects, each evaluated for 10 marks.
Chapters Deleted for Class 12 Mathematics ISC
As per the latest syllabus released for ISC Class 12 by CISCE, there are no topics deleted and the similar structure of syllabus will be followed for the year 2026-27.
Strategic Prep Tips: ISC Class 12 Mathematics Exams
Most students try to study Maths in long, exhausting sessions. That’s exactly why they burn out. Instead, try these smarter hacks.
- Use the 20–20 rule
Study Maths for 20 minutes, then take a 5-minute break. Short focused bursts improve accuracy and prevent mental fatigue.
- Solve only 5 “quality” problems daily.
Don’t chase quantity. Pick five mixed problems from different chapters. This trains your brain to switch concepts quickly.
- Keep a “mistake notebook”
Write every mistake you make and review it weekly. Most students improve marks simply by eliminating repeated errors.
- Start with yesterday’s toughest question
Revisiting difficult problems builds confidence faster than solving easy ones again.
- Practice one mental calculation drill daily
Try solving parts of questions in your head before writing. It sharpens speed.
- End with a “victory question”
Finish your session with a question you know you can solve. This tricks your brain into enjoying the subject.
Consistency beats marathon study sessions every time. Practice daily, but keep it light and focused.
