You reply to your offers in Track. You do not need to reply to your offers until you have received decisions from all your universities or colleges. When they have all sent their decisions to us, we automatically ask you to reply to offers.
If you are waiting for decisions but you are no longer interested in these choices, you can cancel them in Track and then reply to the offers you have already received. It may sound obvious, but check you have received the offers you wish to accept from us before doing this.
