The CBSE board has recently released the most up-to-date curriculum for 12th-class Physics students in 2024. This curriculum is split into theory and practical components, with the theory syllabus holding a weightage of 70 marks.
It consists of a total of 9 units, each containing numerous sub-chapters. In this article, we will present the revised course structure, a list of chapters and topics that have been excluded from the syllabus, and the updated question paper design for CBSE 12th Class Physics.
