Dear aspirant,

Considering the candidate does not get his/her desired branch then first the candidate should wait for the next rounds to get the desired branch. This would be only available if there is any vacant seat in the branch you want.

But let's say at the last you didn't get your desired branch then you will have the option for branch sliding but note this you will have this option if and only if ther is any vacant seat available for that branch. Also note this you have to score atleast above 9.4 cgpa to get your desired branch.
