Hi Hemanth!
CSAB round rules and procedure is as same as that of JoSSA counselling. You will be alloted seats on the basis of category rank (Gen-EWS, SC, ST, OBC-NCL, etc.) if any category seats are available. Then, you will be given seat on the basis of All India rank (CRL) if no category seats are vacant. Visit here to check out the complete procedure:
