CBSE Class 10 Science Syllabus 2022-23: Download class 10th Syllabus PDF

CBSE Class 10 Science Syllabus 2022-23: The Central Board of Secondary Education (CBSE) releases the syllabi for each of its courses annually. The annual syllabus for classes 9th to 12th for the current 2022-2023 academic session is also available now. We have provided below the CBSE syllabus of Class 10 Science. This is the reduced syllabus that will be considered for conducting CBSE Board Exam 2023.

Students must go through this updated Science syllabus before they start the study of a new chapter as some of the topics and/or chapters have been removed from this new syllabus.

In addition to this, they should also prepare the experiments mentioned for the practical work.Taking the practicals lightly may impact your overall results.

Check the complete syllabus below and download the same to refer to as and when required.
