CBSE 2023 Physics Syllabus
Physics forms a major part of the CBSE class 12th syllabus in science. Being the most fundamental unit of science it helps us in understanding the world around us. Thus to score well in the CBSE class 12th boards Physics it is important to have a thorough knowledge of the Physics class 12 chapters. The CBSE board exams are of prime importance in deciding your college and thus these exams cannot be taken for granted.Therefore each subject should be given precise attention.
The Physics class 12 chapters includes nine chapters and hence it is advised that the students should have deep knowledge of the same. So, here is a detailed chapter-wise analysis of topics and their weightage.
CBSE Physics class 12 chapters
The central board of secondary education is the administering authority of the class 12th boards. It is this body that is responsible for forming the CBSE class 12th boards syllabus and thus it is the same body that forms the Physics syllabus too.As per the latest update from the board, no new chapters have been added and no chapters have been exempted from the Physics class 12 chapters.
Getting familiar with the syllabus is important to plan your preparation.Along with chapters, you should acquaint yourself with the marking scheme this will help you know how much time should be allotted to each topic.
