CBSE Class 12 Maths Board Exam 2026: Most Repeated Questions from PYQs

CBSE Class 12 Maths Board Exam 2026, scheduled to be held on 9 March 2026, requires strategic preparation that goes beyond just completing the syllabus. One of the most effective ways to prepare is by focusing on most repeated questions from previous year question papers (PYQs) and identifying high-weightage topics. CBSE frequently follows patterns and often asks similar types of questions from chapters such as Relations and Functions, Matrices, Determinants, Calculus, Vectors, 3D Geometry, Linear Programming, and Probability.

Chapter-wise Weightage Analysis (2023-2025 Trends)

Understanding weightage is crucial for smart preparation, especially if the syllabus is incomplete.

• Unit 1: Relations and Functions (Chapter 1 & 2): 8 Marks Total

• Chapter 1 (Relations and Functions): Approximately 5 marks.

• Chapter 2 (Inverse Trigonometric Functions): Consistently 3 marks.

• Unit 2: Algebra (Chapter 3 & 4): 10 Marks Total

• Chapter 3 (Matrices): Varied (9 marks in 2023/2024, 2 marks in 2025).

• Chapter 4 (Determinants): Varied (8 marks in 2025).

• Unit 3: Calculus (Chapter 5, 6, 7, 8, 9): 35 Marks Total

• Chapter 5 (Continuity and Differentiability): Consistently around 8-10 marks.

• Chapter 6 (Application of Derivatives): Significant upward trend: 6 (2023) -> 11 (2024) -> 15 marks (2025).

• Chapter 7 (Integrals): Decreasing trend: only 4 marks (2024) and 5 marks (2025).

• Chapter 8 (Application of Integrals): Average 4-6 marks.

• Chapter 9 (Differential Equations): Low weightage recently: 2 marks (2025).

• Unit 4: Vectors and 3D Geometry (Chapter 10 & 11): 14 Marks Total

• Chapter 10 (Vector Algebra): Average 5-6 marks.

• Chapter 11 (3D Geometry): Average 7-9 marks.

• Unit 5: Linear Programming (Chapter 12): 5 Marks Total

• Consistently 5 marks. This is a standalone easy chapter.

• Unit 6: Probability (Chapter 13): 8 Marks Total

• Consistently 8 marks. Probability is now simplified.

Strategic Advice for Underprepared Students:

• Focus on Probability (8 marks) and Linear Programming (5 marks) for 13 guaranteed marks as they are easier.

• The first four chapters (Relations, Functions, Matrices, Determinants) combined provide another 18 marks.

• For Calculus, Chapters 8 (Application of Integrals) and 9 (Differential Equations) are relatively easier.

• If you haven't studied Integration entirely, you might strategically focus on either the definite integral part or the indefinite integral part, as there is often a choice. However, for those who have studied, do not skip anything.
