CBSE Class 11 Syllabus Physics for 2023-24 Exams: 

 

Recently, the National Council for Educational Research and Training (NCERT) has dropped several topics from the CBSE Class 11 Physics syllabus textbook to rationalise the curriculum for the 2023-24 academic session. After that, the Central Board of Secondary Education ( CBSE) also developed a more precise CBSE Physics Syllabus for Class 11. 

The restructuring of the curriculum for CBSE Class 11 Physics Syllabus 2023-24 aims to modify the difficulty level of the Physics exam and focus only on significant topics that are relevant today. Hence, students should skip the portions of the syllabus that have been removed from their study plan because they will not be tested on these subjects. The updated CBSE Class 11 Physics Syllabus 2023-24 is in the table below:
