Hi, I,m sorry to inform that with the best of four percentage calculations according to your marks, your chances of getting admission are quite less. If you include all the subjects excluding physical education and paintig, your best of four percentage comes out to be 76%. If you include both the subjects then your percentage comes out to be 81% but still 5% marks will be deducted as these two subjects aren't considered as academic/elective subjects according to DU rules and the list of subjects provided by Delhi University that are considered as academic and elective subjects.

with 76% marks you won't be able to get admission in DU the courses mentioned by you.

Good Luck
