CBSE Class 12th Mathematics Unit-Wise Weightage 2026

Here is the unit-wise weightage for the CBSE Class 12 Mathematics theory paper 2026. This will help students plan their preparation effectively. The theory paper is of 80 marks, and the internal assessment carries 20 marks.

For Theory Paper

There are six units in the Mathematics syllabus, and among these, Calculus carries the highest weightage of all units. Apart from calculus, students must also focus on Vectors and 3-dimensional Geometry and Algebra. There is no chapter-wise weightage, so students must cover all the chapters in a unit.

Units	Subject	Weightage per unit
I	Relations and Functions	8
II	Algebra	10
III	Calculus	35
IV	Vectors and Three-Dimensional Geometry	14
V	Linear Programming	5
VI	Probability	8
Total		80

For Internal Assessment

To score well in Mathematics, students should not ignore the internal assessment marks. The 20 marks for internal assessment are given by schools based on classroom performance, periodic tests, mathematics activities, or portfolio work. Students must score at least 33% in these internal assessment marks to meet the overall passing criteria for the subject.

Particulars	Marks Allotted
Periodic Tests	10
Portfolio	5
Subject Enrichment Activities	5

CBSE Class 12th Mathematics 2026: Typology of Questions and Marks Allotted

How to Score High Using CBSE Class 12th Mathematics Weightage 2026?

To score high marks in the CBSE Class 12 Mathematics board exam 2026, students should focus their preparation using the weightage per unit. Here are 5 simple and effective tips:

Students must focus on high-weightage units such as Calculus, Vectors & 3-D Geometry, and Algebra.
You must also solve full-length practice papers and mock tests to build speed, accuracy, and confidence before the exam.
To make it easy during the last minute, students must make a formula notebook and revise it every day.
After solving practice questions or mock papers, always analyze your mistakes and correct them. This helps avoid repeating errors.

The CBSE Class 12 Mathematics Weightage 2026 helps students to get a bare idea of how marks are distributed across different units in the board exam. Students can check out the unit-wise weightage, which will help them focus on the most important chapters. They must check previous years' questions and solve them regularly to perform well in the exam. So, as a last-minute tip, you must solve previous years' questions, revise formulae, and rectify silly mistakes in the mathematics paper.
