dear student,

it varies from college to college, if you are asking for Delhi university.

It depends on the grade of college and course you are looking forward to get into. North campus colleges would require a minimum of 90%. In South campus the cut offs are usually lower compared to North campus colleges.

You can get the accurate list of DU colleges that you can take admission into on the basis of your XIIth  on thier official sites..

hope it helps!!
