Hello aspirant

hope you are doing great. As per your query  I would like to tell you in simple words about the counselling process of neet or any university . In the start you must have the choice filling , as you said you have been alloted seat in first round so you will get to options either to freeze or float , if you float then you will comes in next around , if higher priorties colleges listed in your choice list  comes under cut off then highest priority college seat will be alloted otherwise you will remain with the previous seat this way all happen

Hope you found this answer helpful. Good luck for your future
