Last Updated : 23 Jul, 2025

In the academic session 2024-25, CBSE has made significant adjustments to the Class 10 Maths syllabus, reducing certain topics (30% of the overall syllabus) to simplify the curriculum and focus on enhancing conceptual understanding and practical application of mathematics.

In this article, we will look at all the topics deleted in the CBSE Maths Syllabus for the board exams in the years 2024-25.

The syllabus for the CBSE Class 10 Mathematics exam in 2024 is structured into two parts:

  • Part A: Comprising of the theoretical component worth 80 marks, and
  • Part B: The internal assessment segment is valued at 20 marks.

Students must achieve at least 33% overall to pass the exam. Below is a detailed breakdown of the chapters deleted from the CBSE Class 10 Mathematics curriculum for the upcoming board examination.
