CBSE Class 9 Science Deleted Syllabus 2023-24: The Central Board of Secondary Education (CBSE) keeps on updating its curriculum to reflect changes in educational standards and to incorporate new developments in different subjects. In a recent syllabus modification, the board cut down the syllabus of Class 9th by 30%. This reduction was made to lighten the syllabus load for students. Thus, for all the class 9 students, it is essential that they have complete knowledge of the chapter and topics removed from the syllabus so that they do not prepare content which is not a part of their latest syllabus. In this article, we have presented the list of chapters and chapter-wise topics that have been eliminated from the CBSE Class 9th Science Syllabus for the academic year 2023-24. The deleted part of the syllabus includes those topics which will not be considered for CBSE Class 9 Science Exam 2023-24. Therefore, students must go through the CBSE deleted syllabus for Class 9 Science to prepare the appropriate content for the periodic tests and the annual CBSE Class 9 Science Exam.
