Hi Vijay,

Now let me tell you about how to include these subjects. Suppose you are applying for BSc(H) chemistry, so you need to take your best of four subjects as English(compulsory), Chemistry(compulsory) and any other two core subjects mentioned above, that's how they take your best of four. Now if you have scored very less in one of your best of four core subjects and you want to leave that subject and include some other subject like physical education, fine arts, vocal music, etc. You can include it in your best of four but 2.5% will be deducted from the total percentage of best of four as these subjects are not considered as core subjects.

Hope this clears your doubt.

All the best. Thank You.
