For the academic year 2020-21, the board has reduced the Class 12 Physics syllabus by 30%. Based on the latest syllabus, the board has released the CBSE Class 12 Physics Sample Paper and marking scheme to give students an idea of the actual question paper. So, they must solve the sample papers and then check their answers by comparing it with the marking scheme. It will help them prepare effectively for the exam.

The CBSE Class 12 Physics Marking Scheme is designed by the Central Board of Secondary Education (CBSE) following certain guidelines. The marking scheme plays a very important role in the exam preparation of students. The marking scheme helps students to analyse the question pattern, the difficulty level, and the question weightage.
