Hello,

As per your query if I assume that you have been allotted a seat in All India Quota Counselling then let me tell you that it is not compulsory for you to accept it. You do have options like cancelling the seat and exiting or take the seat and not proceed for further rounds or you can keep the seat as a floating seat and proceed for further rounds. After that if you get an upgraded seat the previous seat will be cancelled automatically.

Hope it helps.

Good luck.
