CBSE Class 12 Physics Deleted Syllabus 2022-23: Physics is one of the most feared subjects by senior secondary students. With the pandemic halting and changing drastically the school education routine for students, the fear amongst the candidates pursuing Physics has increased a lot.
Although scary from afar, students should pursue their preparation for CBSE Class 12 Psychology examination preparations remembering this quote by Hugh D. Young, “The study of physics is also an adventure. You will find it challenging, sometimes frustrating, occasionally painful, and often richly rewarding.”
The very 1st step to begin the preparation for any subject is to know the total syllabus.

Next, you should move on to your textbook content, solve questions, attempt sample paper and previous year paper by the board and revise it all.
However, CBSE Board has updated the 2022-23 syllabus with many reductions in the CBSE class 12 Physics. So, have a look at the deleted portions from the syllabus to make sure that you are utilising your time, energy and efforts in the right place.
