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 in getting a hold on concepts of Physics. There is no doubt that when we talk about MPC subjects or BiPC subjects, Physics is considered the trickiest amongst 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 and is designed to provide advanced knowledge by brushing up the concepts taught in class 10th and 11th. A detailed analysis of the below-mentioned units will provide a stable foundation of the important principles. The syllabus is bifurcated into 10 units and 15 chapters. The table mentioned below elucidates the chapter-wise distribution of the units of the physics syllabus for class 12:
