ISC Class 12 Physics Syllabus 2022-23

CISCE has released the Latest Updated Syllabus of the New Academic Session 2022-23 on April 21st, 2022, for class 12

Class 12th Syllabus has been revised and changed many times during the Covid situation but finally it released. It’s very important for both Teachers and Students to understand the changes and strictly follow the topics covered in each subject under each stream for Class 12th.

We have also updated Oswal Gurukul Books as per the Latest Paper Pattern prescribed by Board for each Subject Curriculum.

Students can directly access the ISC Physics Syllabus for Class 12 of the academic year 2022- 23 by clicking on the link below.
