This reduction is aimed at reducing the burden and helping students focus more on the real-life implementation of the concepts learnt. While many topics have been removed from approximately 10 chapters, some entire chapters have also been removed from the syllabus. These chapters include real numbers, the area of triangles, proof of some theorems, and more.
The updated PDF of the CBSE 10th Maths deleted syllabus is available on the official website of the CBSE. Students must ensure they check the updated syllabus; failing to do so can result in errors and loss of marks. The CBSE Class 10 Board Exam 2025 syllabus for Maths has been updated to promote critical thinking and focused learning.
