Dear student,

If you do not go any seat in josaa all rounds counseling, then there will be a one option to once again compete for the vacant seats in nits or iiits or gftis and that is - CSAB.

Now, if you didn't got alloted any seat or your seat is cancelled or you have taken the seat and retaining it, then you can participate in csab counseling.

Now for participating in csab round counselling, you have to pay a participation fees of Rs. 36500 (for general and obc candidates ot is 36500 and for sc / st it is rs.16500).

Now if you got allotted any seat during csab round counseling for first time ( means you have not got any seat in josaa), then again you have to pay the seat acceptance fees of Rs. 35000 ( for general / obc).
But if you have got any seat in josaa counselling and you have retained it, then after accepting the seat in csab round you don't have to pay the seat acceptance fees, because it's already paid once.
