Hey Aman!

If you don't pay the required fees for the course in a particular college within the time limit, then your application will be cancelled for that course and college in that particular cut off. But, in the next cut off you are eligible to apply in any course or college matching your eligibility percentage and criteria. In one cut off, you can apply only once. So, yes you just have to check whether you are eligible for a course or not, and if you are eligible you will match your eligibility percentage to that of cut offs presented by various DU colleges. Once selected, you can apply and also keep in mind the category. For example, if you are a general category student you will have to look for cut off for general category only.

All the best!
