Hey Arun,

University of delhi is one of the prestigious university we have in India. Being one of the top college the cutoffs of this college always be high. It would be difficult for to get admission in the top colleges of du if you belong to general category. But with 90% you may get admission in south and off campus colleges in DU for bsc courses.

In order to check the cutoffs of different colleges you may go to the official website of the DU and get a clear idea regarding colleges you may get accordingly.

Hope this helps , if not do ask!
