Hi,

In a particular round, you can change your preference as many times s you want. Only the latest change you made, will be considered during college allotment process. The college will be allotted to you based on your preferences, the algorithm will try to give you college you prioritize based on your rank and cutoff.

If you are allotted with some college,and there are further rounds remaining, you might have options like Freeze, float and others with their definitions based on your counselling. Please read these definitions carefully , then proceed, as it might fix your college and you can not participate in further rounds or even there might be an option for exit the counselling process, and you lost your this year chance!

I hope it helped.

Thank you!
