Hello there, if you choose to move to further rounds after getting a college in previous rounds it means you are leaving that seat and making it available for another student. Then if there are seats in the college you wish for in further rounds, that seat will be yours. And if you choose to play further round that is mop up round, the seat you got in last round will be again alloted to another student.

Basically it's just that simple. As you move ahead with the rounds you got to leave the seat empty and you will not get to turn back to that seat again once you are forward with your counselling.

Thank you. Hope this helped. Check out the link and predict your rank below on the link.
