Dear Student,
Sorry to inform you but with even 80.6% in your 12th it is next to impossible for you to get admissions in the University of Delhi as the cutoffs are quite high and for general category the cutoffs usually don't get below 90% in any of the college in DU. The demand for courses like B.com and B.com hons are quite high and so are it's cutoffs and for general category it is way too high and doesn't falls below 90%.
Hope this might help you.

You can go to DU but you will not get college of your choice (if you are genral) , by some source or connection or even  by management Christ University Bangalore is easily achievable.
