No, this isn’t the case. A university or college should try to make their decision within 21 days, but sometimes they need longer. The ‘Add an Extra choice’ option will automatically become active again after 21 days. You must then decide whether to keep waiting for the university or college to make a decision, or to replace it with another choice instead. However, if you do replace it with another choice, this will prevent the university you are waiting for from making their decision.
