CBSE Class 12 Physics Syllabus 2022-23
CBSE class 12 physics syllabus 2022-23 has been released by the Central Board of Secondary Education on its official website. The Board made it very clear that there are no changes in the CBSE class 12 physics syllabus 2022-23 and it is basically similar to the Physics syllabus for the year 2021-2022. No addition or reduction has been done in the Physics syllabus. The Scheme of the Examination is also the same as that of 2021-2022. A theoritical exam would be conducted on 70 marks and a practical examination, which includes two experiments, accounts for the 30 marks.
