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.

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.
