Physics Syllabus Class 12 2022 - 2023: CBSE Syllabus plays a major role in helping students prepare an effective study plan. In fact, the syllabus of each subject does not server as a roadmap for the students board examination but also for many competitive exams ahead.
The Central Board of Secondary Education (CBSE) has released the revised syllabus for the class 12th for the 2022-2023 session. We have provided below the revised CBSE Class 12 Physics Revised Syllabus which students may read and download in PDF.
This syllabus mentions the details of the course structure for the theory paper and the practical exams. Students must follow this latest syllabus to study the prescribed chapters and topics only and avoid the content dropped for the current academic session.
You can visit CBSE Class 12 Physics DELETED Syllabus to check the topics that have been removed from the syllabus for 2022-23. These topics would not be evaluated either in school assessments or board examination.
