# Physics Syllabus for Class 12

We all have gone through the struggle of arduously preparing for the class 12th board examinations. Out of all the Science stream subjects, most of us have struggled to get a hold of concepts of Physics. There is no doubt that when we talk about MPC subjects or BiPC subjects, Physics is considered the trickiest of all. Thus, it is essential to understand the physics syllabus in detail to start a career in Science after 12th. The physics syllabus, as designed by the Central Board of Secondary Education(CBSE) for class 12th involves an intensive study in the domain of science. It is designed to provide advanced knowledge by brushing up on the concepts taught in classes 10th and 11th.
