I think the real question is if you are CPR, are you REALLY CPR? When you look at past years and you see candidates being CPR until April 14th and then receiving a rejection, one might make the conclusion that CPR is just a placeholder (i.e. A decision has already been made but for some reason not communicated/portal updated). I kind of doubt all those rejections are decided on the last day. On the flip side, you could say that admissions is just keeping their options open and the reason many do not receive rejections earlier is because there is still some possibility of appointment. The truth is, only people who have worked in the inner circle of admissions know. I am just guessing here.
