Hi. Yes, you can get admission in DU but your admission depends on following things :

1. The subject and college you have targeted for your graduation. If you want to study in North Campus colleges with subjects like economics, chemistry, accountancy, political science etc. It (http://etc.it/) is ne (http://etc.it/) xt to impossible because cut offs are too high.
2. Reservation : If you have any reservation quota like SC, ST, OBC or PWD that increase your chances to get admission in some good colleges. Also, if you are from CW category you have a chance to get good course from prestigious college.
3. Sports quota : If you are good in sports and play matches at higher levels (state or national) you can apply from sports quota.

Don't worry if you doesn't have any of the following things, there are some other ways to get admission in University of Delhi:

1. Try to get admissions in South campus colleges or some Off Campus colleges (Maharaja Agarsen College, Aryabhatt College, Rajdhani College etc).
2. There is also entrance examination to get admissions in DU for some limited courses like BMS, BBA in finance, BBE. Exam is known as DU-JAT forms are out in first or second week of April. You can study all three management courses in your undergrad. But requirement is : you have to study maths in your class 12th and got percentage above 60% in best 4 subjects.

Hope this helps.
