Hello Rajesh,

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, your best of four will include Physics, Maths, Hindi and Chemistry. Therefore your best of four percentage will be: 96%

With this much percentage, there are high chances that you can get a seat in one of the top colleges of Delhi University in North campus.

Hope this helps! All the best for your career!
