Hi Aspirant!

According to official guidelines, only the fresh candidate have a right to fill their choice.Mean to say the students who again pay the new fees or firstly taking participation in round 2 can fill their college choice.Hence as you already participated in round 1 you can not rearrange your choices.

I hope it helps.
