Hello,

After knowing the results, you will be called for counseling according to your ranks. On the day when your rank is being called, at the counseling venue, available seats would be shown for you out of which you will choose one and register. Whether to lock that seat or you plan to attend another further counseling too, that would be upto you. If you lock that seat, you will get admission in that seat only. If you register for that seat and still wish to pursue further rounds to get other seats, the same process of counseling would be repeated.

I hope this helps.
