CBSE Class 9 Deleted Syllabus 2022-23: All of the Class 9 texts have been reviewed by the National Council of Educational Research and Training, or NCERT. The class 9 books' contents have been rationalised by NCERT. The textbooks' contents have been streamlined to take into account content overlaps with identical material included in other class sections as well as material covered in either the lower or higher class for the same subject. Verifying the content's degree of complexity was another criterion taken into account.
As a result, some important chapters and topics from the Class 9 NCERT Books have been removed. Here is a list of the chapters and subjects that were dropped from the class 9 textbooks.
