Hello student,

As you should know that delhi university the four subject that Delhi university will consider for merit list includes:

• Three core subjects ( PCM for science steam)
• A language subject i.e English. 

So it should be clear to you that you can't add physical education as your fourth subject until you get admission through sports quota. 

On the other hand you should keep in mind that the cutoff list for hons. always goes to high.

Hope it helps. 

Thank you  :)
