Dear candidate.... hope you're doing good..

Well, to be in the process of counselling, you have to first of all, accept the seat offered to you in the first round of counseling. Then only you will be eligible for further counseling process and by choosing the option for float, you may also avail any upgradation if possible in the successive rounds of counselling. But not paying the seat acceptance fee and not doing documents verification may cancel your application and you may be out of counselling.

Hope this helps you out....

Best of luck:)
