Hey Manav,

DU is one of the prestigious university of India and therefore usually keep their percentage high. It would be very difficult for you to get admission in 79.4%.  Also DU takes admission on the basis of your best 4 percentage and not on your total aggregate. If your best 4 percentage is above 80% you may still hope to get some off campus colleges. The best 4 percentage is calculated taking your best 4 subject you scored the highest.

Hope this helps, if not do ask!

Good luck!
