4. Vectors and 3D Geometry – 14 marks combined; numerical-based and scoring.

5. Probability – 8 marks; needs practice to avoid calculation mistakes.

6. Matrices and Determinants – 10 marks; essential for understanding transformations.

Deleted Syllabus for Class 12 Maths 2025

The Central Board of Secondary Education (CBSE) has reduced the Maths syllabus, keeping in view the pressure on students. For the 2025 board exams, certain topics have been removed. Students should refer to the latest official CBSE syllabus PDF before starting their preparation.

Deleted topics include:

• Some parts of Sets and Relations (already covered in Class 11)

• A few sections from Probability that involved advanced formulae

• Some applications of Calculus for lengthier derivations

CBSE Class 12 Maths Internal Assessment Marks

The internal assessment is allotted 20 marks and plays an important role in a student's final percentage. Students will be assessed by their teachers based on their class performance, lab manual work, and participation in mathematical activities.

Weightage of Calculus, Vectors, and Algebra

Calculus, Vectors, and Algebra are allotted the highest weightage in the exam among all other units. These three units together make up nearly 75% of the total marks allotted to the theory paper.

To score high, students should focus on practising numerical questions from the said topics regularly and revise all formulas from the NCERT examples.

How to Prepare for Class 12 Maths Exam?

Some simple and effective tips to prepare well for the CBBSE Class 12 Board Exam are as follows

1. Study according to the weightage: Start with the high-weightage units like Calculus and Vectors.

2. Use NCERT as the base book: All CBSE papers are based on NCERT concepts. Solve each example carefully.

3. Make a formula Note: Revise all formulas daily to improve speed and accuracy.

4. Practice previous year papers: This helps you understand question patterns and time management.

5. Attempt sample papers every week: Helps identify weak topics early.

6. Focus more on Conceptual Understanding: Learn the logic behind formulas and theorems.

7. Keep time for revision: Revise at least twice before the board exam.

8. Stay calm during the exam: Read each question carefully before solving.

CBSE 12th Maths Board Exam Tips

Some of the important CBSE 12th Maths Board Exam Tips to help the students score well in the exam are as follows:

• Start with easy questions: This builds confidence and saves time.

• Write step-by-step solutions: Even if your final answer is wrong, you can get step marks.

• Draw diagrams in 3D Geometry: Visual representation adds clarity.

• Recheck calculations: Silly errors often cost 5–10 marks.
