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:
- NCERT has just now uploaded PDFs for all Class 11 subjects with their deleted chapters, topics and subtopics as per the CBSE rationalised syllabus for 2025 exams.
- This reduced syllabus to be followed from 2022 session seems to be permanent and could be followed in competitive exams like NEET and CUET in the coming year.
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.
NCERT Class 9 Rationalised Topics PDF
Below, we have provided up all the reduced topics for all subjects in tabular form.
