Dear student,

If you got allotted any seat in josaa counselling then you can either slide or float it.
Now if you slide for float your allotted seat then that means you have accepted the seat and you want to get higher preference branch in same college or different college in further rounds and if you get, you will take it.

Now, if you got allotted any seat in josaa counselling and you have used slide or float then that means you have retained your seat. Then also you can participate in csab counselling. So, again you will have to pay fees of participation and if you get any seat in csab counselling and if you accept it, then your josaa seat will be eventually cancelled.
