Just got off the phone with prometric and sun education. The certification exam has to be completed within one year or the expiration date on the voucher. I bought mine Jan 05 and it expires Jan 06. I was under the impression that I can reschedule the exam beyond, but keep getting the message "You are about to reschedule the exam listed below. You must click the appropriate button to process your request. Failure to do so will result in your current appointment not being rescheduled."
Hnn. My understanding of the process has always been that you need to schedule it within a year, but that once you do that, it's between you and Prometric as to when it gets taken. I suppose this is a good thing to know, if Sun's own policy is different.
