Hello candidate,

According to the last report updated by the Central Board of secondary Education, there has been no such reduction in CBSE Syllabus 2021-22 for classes 9th, 10th, 11th & 12th.

Moreover, as per this CBSE Syllabus is applicable for Academic Session 2021-22, so students preparing for CBSE board exams 2021 has nothing to do with this syllabus.

Hope you found it helpful. If you have any further queries feel free to post it here!!
