CBSE Class 9 Science Syllabus 

CBSE Class 9 Science Syllabus 2022-23: The board has issued the CBSE Class 9th Science Syllabus for the upcoming academic session (2022-23). The syllabus has been updated in accordance with the annual assessment process. It is a condensed syllabus, around 30% shorter than that of 2019. As a result, students should go through the entire syllabus and only study the chapters/topics specified in the most recent syllabus. A list of experiments for practical work as well as internal assessment details can be found below. The CBSE Class 9 Science Syllabus 2022-23 can also be downloaded from this page.
