Hey,

It is necessary for you to include one language subject in best 4 calculation. Including English is not necessarily required until it be the only language subject you've  studied in class 12th. For example If you've studied english as well as hindi in your 12th then you may include hindi instead of English if you've scored more in it for calculating best 4 percentage .

For calculating best 4 you have to include one language subject whichever be your core subject and which is also included in the elective subject list of du.

Hope this helps! 

Hey Priyanshi,

As per Delhi university your top Four subject marks are calculated to get an average and yes English is Compulsory among them. So basically English and rest top 3 marks are calculated. This year I've  heard that DU has made some subject compulsory for some courses like maths in economics based. 

Best of luck
