CBSE Deleted Syllabus For Class 12 Physics: Physics is a very important and main subject of Class 11 as well as Class 12. Whether a student is from Medical stream or Non-medical stream, physics subject is equally important to both of them. Physics is a concept based subject. So if a student’s concepts are not clear, he/she cannot score good marks in this subject. Physics is one of the toughest sections in Science stream examination. So student needs to practice well for scoring high marks in this subject.
CBSE Deleted Syllabus For Class 12 Physics
Due to the Covid-19 situation, no proper school functioning is taking place. There is a increasing stress on student’s shoulders and it is very difficult to cover entire syllabus in online classes. So CBSE has decided to reduce the syllabus by 30% of all classes.
Here student can check the deleted portions from Physics subject for Class 12 2020-21 academic year:-
