Hello  dear  student!

Cut off of Delhi University changes every year and it also depends on the course as well category you belongs to. For microbiology course, with this much percentage it is almost impossible  for you to get admission  in Delhi University if you  belongs to unreserved  category. But if you belongs to any reserved category, then there are chances (still very less) that you get enrolled in some less famous colleges of Delhi University.  Meanwhile,  you can apply via sports quota if you're  eligible  for it, then also the chances increases a bit.

hope this will help you

All the best
