Dear Parmar

As I'm from Ap and I gathered enough information to satisfy you. Here, after diploma  we need to take ECET test so if you get 1000 below rank you can able to get into top 10 colleges and also if you want to go to another state with these rank also you can go but that government won't give reimbursement option. If you really want the selected college /university they are sine seats under management quota but you need to pay the extra amount to book that seat.

All the best.
