If we look closely at CBSE Class 11 Syllabus, there are quite a few topics and chapters that were previously deleted from the syllabus and now have been added. Instead, some other topics/ chapters have been deleted.
Moreover, given below is a latest update from NCERT regarding their Class 11 syllabus as well:
NEP 2020 provides instructions to take load off of students so they can indulge themselves in competency-based learning instead of rote memorisation. This is why the syllabus has been reduced multiple times in the past couple years.
So now finally NCERT has updated all these deleted chapters and topics for Class 9 to 12 textbooks so students may not follow them for board preparation.
Below, we have provided up all the reduced topics for all subjects in tabular form.
