Overview of ISC Class 12 Mathematics Exam Pattern

The Council for the Indian School Certificate Examinations (CISCE) has unveiled the exam pattern for the ISC Class 12 Mathematics for the academic year 2026-27. The examination is set to take place on March 1, 2027. This new pattern will help students grasp the structure of the question paper and the distribution of marks across different topics.

Details of the ISC Class 12 Mathematics Exam Pattern

For the 2027 examination, the CISCE has implemented a four-section format where all questions are mandatory. This is a shift from the previous format, which allowed students to select between Section B and Section C. The total marks for the exam are 100, comprising an 80-mark written paper and a 20-mark project component. Students will undertake a 3-hour theory exam and complete two Mathematics projects for internal assessment.

Marks Distribution by Mathematics Unit

The ISC Class 12 Mathematics syllabus is divided into seven units. The unit on Calculus holds the highest weightage at 35 marks, making it crucial for students. The marks distribution is as follows:

Unit	Marks
Calculus	35
Relations and Functions	10
Algebra	10
Probability	9
Vector Algebra	5
Three-Dimensional Geometry	6
Linear Programming	5

Students are encouraged to focus on Calculus, as it constitutes a significant portion of the theory paper.

Structure of the ISC Mathematics Question Paper

The theory examination for ISC Class 12 Mathematics will last for 3 hours and be worth 80 marks. The sample question paper for 2027 is organized into four sections: A, B, C, and D. Unlike previous years, where students could choose between Sections B and C, all questions must be attempted in the 2027 format. Internal choices are available for certain questions in Sections B and D. The marks allocation is as follows:

Section	Marks
Section A	20
Section B	14
Section C	21
Section D	25

Marking Scheme for ISC Project Work

In addition to the written examination, students are required to complete two Mathematics projects, which collectively carry a weightage of 20 marks. Each project is assessed out of 10 marks based on four criteria: overall format, content, findings, and a viva (oral examination). The total assessment for both projects contributes to the overall score.
