Hey

Physical education is not considered as a core subject therefore you can't add physical education while calculating your best of four percentage.

For the calculation of best of four percentage, 1 compulsory language subject and 3 elective subjects are taken into consideration. Delhi University has its own criteria for calculating the eligibility for getting admission therefore the subjects are to be chosen from the list A and list B prescribed by the university itself.
