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 music, your best of four percentage comes out to be 68.75%%. If you include both the subjects then from your final percentage 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 68% marks you won't be able to get admission in DU throug general category in the courses mentioned by you.

Good Luck
