if a person under sports quota is including physical then too the 2.5% deductions will be there ?

If you are not applying for Physical Education(Hons) in a DU college, Physical Education won't be considered a List 'A' subject for the calculation of Best Four, even if you are applying under the Sports quota. Hence, for any other course in DU(Hons/Prog), adding Physical Education in the Best Four subjects will result in a deduction of 2.5%. The applicant can apply for the Sports quota after he/she has entered the marks and no subject studied in Grade 12 has any relation to it. You can find the procedure of subject selection for the calculation of Best Four here: https://university.careers360.com/articles/delhi-university-admissions-how-calculate-best-of-four-marks
