Hey,
Well, the University of Delhi is one of the best in country and when it comes to Humanities, it is simply the best and that makes it the most sought after and therefore the competition is quite tough also because the admission to Bachelor of Science and Bachelor of Arts is through Merit based. The cutoff goes very high and yours is unfortunately very less. However,you can apply for the vocational courses offered by the Delhi University and also to DU SOL(Delhi University School of Open Learning).
See,marks cannot stop you from achieving your goal and you can go for other good universities where admission is given on the basis of your performance in the given entrance exams.
Hope this helps.
Good luck.

Hey Diwakar,
Colleges of Delhi University are the most sought after colleges in India. There cutoffs are really and their is a  very tough competition to get admissions in the desired course in Delhi University.
You percentage is not really up to mark for getting admissions in any college of DU. You can look forward to other colleges in India. Even if you get admissions, you may not get your desired courses.
Good luck! :)
