Yea, but to anyone that retains the application will think nothing of it until the PCAT comes in...At that, your application being on hold may not "fan" out as quickly as others who have already taken the PCAT (since its a big part of the tally for interviews). I would call each school to see if they have recieved your PCAT. Id personally just wait until you have taken the PCAT so that your application will be fresh on a committees viewpoint WITH the PCAT at hand.
