Hello Rahul,

While calculating best of four, the following subjects are considered:

• One language
• One subject in which admission is sought
• Any two other academic subjects as per list A offered by University of Delhi.

You can check the subjects included in list A at this link: http://www.dr.du.ac.in/adsubjects.php

In your case, English, Mathematics, Physics and Computer Science will be included while calculating your best four. Your aggregate best four marks are: 90.25%

Hope this helps. All the best for your career!
