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 Applied 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.

**Class 12 Applied Mathematics Reduced Syllabus for 2021-22 (Reduced)**

We have also provided the syllabus for the 2021-22 session that was previously restored so that you can compare the deleted and added topics.
