Hello Sanjana!

Yes you can. But you need not make a fresh registration for that purpose. You can just login using the credentials of first round and fill choices for deemed universities. You can apply for the Deemed Universities by paying Rs.2,05,000 as a refundable/adjustable amount if you take a seat. And if you are getting seat, then you cannot leave it until you get your security amount refunded. The no.of choices you can fill is also not limited, so you can make as many choices you want.

You can also participate in the mop up round for deemed/central universities. But you have to make a fresh registration for the mop up round.

You can get a list of colleges that you have chances to get using our college predictor. It would help in your choice filling process:-
