ISC Class 12 Maths Syllabus 2025-26, Check Marks Distribution

ISC Class 12 Maths Syllabus 2025-26: The ISC Class 12 Mathematics syllabus for the 2025–26 academic year has been released by the Council for the Indian School Certificate Examinations (CISCE).

The exam pattern includes two papers: Paper I (Theory) carrying 80 marks and Paper II (Project Work) carrying 20 marks. The theory paper encompasses topics such as Relations and Functions, Algebra, Calculus, Probability, Vectors, and Three-Dimensional Geometry.

To excel in the examination, students are advised to thoroughly review the syllabus, understand the exam pattern, and practice extensively using ISC 12th previous year papers and ISC class 12 sample papers.

These resources aid in familiarizing with question formats and enhancing problem-solving skills. Regular practice and adherence to the syllabus can significantly improve performance in the board exams.

Detailed ISC Class 12 Maths Syllabus 2025-26

Here we have provided an overview of each unit in the ISC Class 12 Mathematics syllabus based on the image:

Section A: 65 Marks

1. Relations and Functions
   Covers types of relations and functions, domain, range, and composition of functions. Focuses on understanding basic mathematical structures and their properties.

2. Algebra
   Includes topics such as matrices, determinants, and the inverse of matrices. Useful for solving systems of linear equations and transformations.

3. Calculus
   The most heavily weighted section. Covers limits, derivatives, applications of derivatives, and integrals. It builds essential analytical skills and forms the core of higher mathematics.

4. Probability
   Involves conditional probability, Bayes’ theorem, and probability distributions. Helps in understanding uncertainty and decision-making

Section B: 15 Marks (Choose any one section between B and C)

5. Vectors
   Focuses on vector algebra, including scalar and vector products. Useful in physics and geometry.

6. Three-Dimensional Geometry
   Covers direction cosines, equations of lines and planes, and angles between them. Applies to spatial understanding and modeling.

7. Applications of Integrals
   Deals with calculating areas under curves and between curves. It links calculus with geometric visualization.

Section C: 15 Marks (Alternative to Section B)

8. Application of Calculus
   Involves problems on maxima, minima, and optimization. Applied in economics, business, and engineering.

9. Linear Regression
   Introduces statistical techniques for modeling and analyzing relationships between variables.

10. Linear Programming
    Teaches optimization under constraints using graphical and algebraic methods. Important in operations research and management.

Preparation Tips for ISC Class 12 Maths Exam 2025-26 

Here are some preparation tips for the ISC Class 12 Maths Exam 2025–26:

 1. Prioritize High-Weightage Chapters

• Focus first on Calculus (32 marks) and Probability (13 marks) as they together account for over 50% of the paper.
  
  

• Master the basics of Algebra and Relations & Functions early to reduce stress during revision.
  
  

 2. Stick to the ISC Syllabus

• Don't waste time on irrelevant topics. Cross-check every topic with the official 2025–26 syllabus PDF.
  
  

• Use ISC-specific books like ML Aggarwal and understand past trends in ISC questions.
  
  

 3. Maintain a Formula Booklet

• Keep a separate notebook for all formulas, theorems, and standard results.
  
  

• Revise it every week to ensure retention without last-minute cramming.
  
  

 4. Previous Year Papers Are Gold

• Solve last 5–10 years' papers under timed conditions.
  
  

• Focus on how questions are asked and recurring question types in Calculus, Probability, and Geometry.
  
  

 5. Mock Tests & Self-Assessment

• Schedule a weekly full-length mock test at least 2 months before the board exam.
  
  

• Analyze errors, revise weak areas, and track progress.
  
  

 6. Don’t Ignore Section B/C

• Even though it’s 15 marks, topics like Vectors, Linear Programming, and Applications of Integrals can fetch full marks with conceptual clarity.
  
  

• Choose the section that best matches your strengths.
  
  

 7. Presentation Matters

• Write step-by-step solutions neatly with proper margins.
  
  

• Highlight final answers and box them to catch the examiner’s attention.
