NCERT Rationalised Content for Class 9 Check Deleted Chapters & Topics: The National Council of Educational Research and Training (NCERT) has recently revised all Class 9 textbooks, rationalizing their contents. This rationalization process involved streamlining the content to avoid overlap with similar topics covered in other subjects within the same class, as well as with content covered in lower or higher classes in the same subject.
The difficulty level of the content was assessed, leading to the removal of some significant chapters and topics from the Class 9 NCERT Books. Below, we provide a list of the removed chapters and topics, along with their respective page numbers. For students preparing for the CBSE Class 9 Exam 2024-2025, it is essential to refer to the revised NCERT Books, the download links for which are provided below.NCERT Books for Class 9 2024-25 Download Subject Wise PDF
