Syllabus For Class 11 Physics

The new updated CBSE class 11 physics syllabus 2018-2019 is available here. The syllabus has been developed with a view that this stage of school education is crucial as the transition from general science to a discipline-based curriculum occurs. The syllabus is designed in such a way that it will help learners develop an active interest in Physics as a discipline. It aims at inculcating in learners the abilities, useful concepts of Physics in real-life situations for making learning of Physics relevant and interesting. Referring to the class 11 physics syllabus provided below helps you plan an effective study routine and study efficiently. One can access the syllabus whenever necessary for free.
