Hello aspirant. There are plenty of colleges available in Delhi NCR. The rankings of colleges varies from course to course. Since you have not mentioned the course you are looking for, I am providing you with a general answer. You need to fill seperate forms for all colleges or universities and if you are applying for more than one course in the same university, then also you need to fill seperate form. If you are eligible for a government college, then make it as your first priority. Else there are private universities available. I hope you found this answer helpful. Good luck.
