Hello Aspirant,

As you mentioned that you have applied for float option in the csab round and you have got the upgraded option in the second option so that is your final branch , you cannot go back to the first branch that you got in the csab round 1. You need to go for this current branch or you have to leave the seat .

If you would not got any seat then you would have received the branch that you got in the csab round 1.
