Hi Nandlal,

If your question is about JOSAA counseling then, No, you would not have to go to the reporting center again. Whatever college you get in last round, automatically gets frozen. You will directly have to report to the allotted institute with required documents. And within a few days your class would start.

All the best

In the last round you need to freeze your seat in order to get that seat and if you keep on floating in every single round then you shall get upgraded to the uplisted seats. YOu need to keep on chossing between the options given. Choose either of them as per your choice but you need to as in josaa if you didnt do it then you are not eligible for the next round.
