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.
