Yes , you can try getting admission for different streams of B.Sc or B.A in Delhi University . Delhi University intake students for B.Sc and B.A. programs by class 12 board results.

You just have to fill an application form by following this link :-

In my opinion , as per your score you should get a decent college in DU for B.Sc as well as B.A. programs.

You can check previous year cut off for all the courses by following this link to get a better idea:-
