Hello Mohit...

I am assuming you as a general category students, According to that yours marks are not so satisfactory for getting admission. You cannot get seat in DU good colleges because those colleges seats get filled by 3rd round cutoff according to previous years cutoff from its official site.

You can only get seat in college if you are not a general category student because many colleges cutoff marks never come below 80% most of the years for general category students. Else you can check CUTOFF list from our site below
