hello aspirant,

it actually depends on college to college ,if you can add the subject or not

if you are talking about DU ,In science stream, DU doesn't see the best four marks, but they see the overall percentage scored .Physical education marks can be included in the best four subjects if it is a core subject.But if it is an optional subject then can't include in it.

if you still have doubts uncleared, get back to us in the comments section.

hope that helps

all the best
