Hi,

Generally EVS is an optional subject for the students so it may not be included in best four.Since it is not a core subject so it won't be considered in best of four whille calculation of your percentage.

A language subject is however very important for getting adm ission in DU University.

While reading your subjects I didn't come across any language subject. Make sure you have because the delhi university includes a language subject in best four in all its courses while giving the admission.

Hope it helps!
