Hello Anuradha.

The chances for you to get a college in the spot round will totally depend on the availability of seats. You must be knowing that in the spot round the vacant seats are filled, where the number of these vacant seats are not fixed and it totally depends on the number of students who have taken admission in the prior rounds of counselling. There might be many more students with ranks better than you waiting for this college but you can still give it a try and you may get a seat with this rank. It will also be smart to keep a backup college just in case you don't get your desired one.

Hope that helped.

All the best!
