Hello, 

Once counselling starts , then you have to fill preferences of college and branch . Suppose you got a seat in some xyz college and you are happy with it . Then you will confirm your seat by paying seat acceptance fee. Before reporting at nearest reporting centre , login on josaa website then you need to fill reporting centre , date of reporting . Then you will be given a provisional seat allotment letter , which you have to submit while document verification.

Hope it helps. You can ask any queries.

Thank you.
