I am trying to reschedule my exam on prometric but the last available day shown is June 2nd, and then no availability at all after that (for all testing centers). I would find this pretty hard to believe...Can someone please tell me if they were able to schedule in June/July/August and how the availability was? When I just browse/locate testing centers and check availability that way, it shows plenty of availability for several months. But when I actually try to reschedule by entering my confirmation number etc, the last available day (for me at least) is June 2nd. Is there a time limit on how far out you can reschedule from your initial registration date?
