Dear aspirant,

This is a very common doubt which generally stays among the students that if their seat will stay if they chose for float option for the next round.

So, in josaa I would recommend you to kindly watch till the last round which branch are you getting and if it doesn't change till last round so you would get 20th position choice as your final branch.
