If you receive an unsatisfactory college in the first round but hope for a better one in later rounds, you have a few options: accept the first-round seat and participate in further rounds for upgradation, or reject the first-round seat and wait for the later rounds.

If you choose to upgrade, you can apply for upgradation during the second round while holding your first-round seat. If you get a better college in the second round, your first-round seat will be canceled.

If you don't get a better college, you'll retain your first-round seat. If you reject the first-round seat, you'll have to wait for the subsequent rounds for a better chance. It's recommended to carefully evaluate all options and make an informed decision based on your preferences and priorities.
