To be honest, there is no way to know that the seats are filled.
Suppose there are 10 seats and 20 students. In first round, top 10 students will be alloted the seat. However, there might be possibility that the 1st student gets a better college. So, he leaves his seat. In second round, the 11th student gets the seat.
I guess this will help you out.
