Dear Student ,

No.. As you know that , to get admission in CSE .. you need to appear for JEE MAIN exam . and as per the subject combination rule, you need to have PCM combination as compulsory subjects in 12th qualifying exam .

That's why, Physics should be in your subject combination category .

Well, you may keep Computer science as your optional subject.
