Hey!

Yes, you can get admission in Delhi University at 80%( I am assuming that it is your best of four percentage). You can get admission in 6th or 7th cut off list. If you have a valid OBC certificate which is either centrally valid or belongs to Non- Creamy Layer then you can get admission with the help of the certificate in maybe 5th or 6th cut off list otherwise you have to get admission under the unreserved/ general category
