CBSE Class 12 Physics Syllabus has been released for the 2022-2023 session on the official website of CBSE. CBSE will now conduct the only one final exam from the next academic year. This means that the system of division of CBSE Class 12 Exams into two terms has now been discontinued. 

Class 12 Physics Exam is divided into Theory and Practical sections. The theory exam will be of 3 hours and will cover 9 units and will be of 70 marks. 30 marks will be assigned to the Class 12 Physics Practicals.
