Hey Alok!

For getting enrolled in the course of B.A.(Honours) Philosophy in University of Delhi (DU), no percentage deduction will be done if the candidate has not studied Philosophy in their 10+2. Earlier there used to be deductions but now no deduction for not studying philosophy in 12th class. So, you can calculate your best 4 percentage without facing deduction for not having studied philosophy before. But, keep in mind that you may be subjected to deductions in your best four percentage if you don't don't fulfil other criteria's such as choosing of subjects from the list A and B. For example, if you add physical education or music in your best of four for courses that are not associated with these subjects then you may be subjected to a deduction of 2.5%.
