List of Rationalised Content in NCERT Books for Class 9: The National Council of Educational Research and Training (NCERT) has reprinted and published the new editions of class 9 books after rationalising the content of the books. Contents of the textbooks have been rationalised in view of overlapping with similar content included in other subject areas in the same class and similar content included in the lower or higher class in the same subject. Another factor taken into consideration was to check the difficulty level of the content. Thus, some of the significant chapters or topics have been deleted from the Class 9 NCERT Books. We have provided here the list of the chapters and topics removed from the class 9 books along with their respective page numbers.
