Hi Sumit,
Delhi University is the most reputed university in India. It is very much popular and the toppers of the state boards and CBSE aim to get in DU. So, the cutoff is also very high and you are required to get a minimum of 95% marks to get into colleges affiliated to this university. At 79% it is almost impossible to get into DU.

I hope this information helps you.
Good Luck!
