Hello Riya, 

The seat vacancy only depends on the number of seats alloted in the earlier rounds of counselling and to get the exact details about the total number of seats remaining for allotment and the cutoff marks and ranks which goes varying according to the subsequent rounds. You will get the exact information on the official website.
