**CBSE Class 11 Physics Syllabus 2022-23: **The class 11 Physics syllabus for the academic year 2022-23 has been released on the official website. The Physics syllabus is divided into two parts, that is, 70 Marks for theory and the remaining 30Marks for Practicals. In this article, we have thoroughly covered the detailed syllabus. Class 11 form the base for competitive exam such as IIT-JEE, NEET Exams, etc. Often students consider physics one of the toughest subjects among all others. But if you go through the concepts and understand them well it would a cakewalk for you. So, Physics is divided into two parts, Part A for Class 11 and Part B for Class 12. Scroll down first to understand the syllabus.
