When you are not satisfied with the college and branch you've got and aim for a better seat you go for float. It means you have been allotted a seat and you’ve accepted the seat but you want a better programme (quite obvious) than what you’ve been allotted. In this case once you are allotted a seat in the further rounds, you’ll lose the seat which was allotted previously. And the choices considered for float will be the ones which are above the allotted programme in your filled choices list. So it’s very important to fill choices intelligently.
