CBSE Syllabus Class 12 Mathematics

On July 5, 2021, CBSE had announced that the Syllabus for Class 12 Board Exams will be reduced as per a Term-based Examination System and on July 22, 2021, they finalised the reduced syllabus as well by providing updated PDFs.

CBSE Class 12 Syllabus has undergone drastic changes since the previous 2020-21 session. Due to the COVID-19 pandemic, the education system has been challenging for both teachers and students.

So, similar to the 30% reduction in the last session, CBSE decided to reduce the overall syllabus according to the Term-based Board Examination for the 2021-22 session again.

We, at Educart, were prompt about it and have updated the changes in all the subjects for you. Here, you can find:

  • freely-downloadable PDF links to the latest reduced Class 12 Mathematics Syllabus for 2021-22 academic session; and
  • simple analysis of all the deleted topics/ chapters for 2021-22 Term-based Board Exam.

With all this information in hand, both teachers and students will have a defined structure to begin the learning process on time and efficiently.
