That's not a motivational statement.

I accidentally scheduled an exam on the opposite side of the state (Prometric gives you all testing centers in the state, not those closest to a particular ZIP code like, well, any other modern website). This is two weeks out, did not think it would be a big deal. Realized it a minute or two after the fact. Went to correct the error and, lo and behold, there is a $35 fee to reschedule. Had no idea about it until it was too late to avoid incurring the fee. Not optimistic that I can do anything about it at this point, but don't make the mistake I did!
Don't get sick, don't have any emergencies! Let nothing get in the way of that certification exam

Anyone else discover this the hard way?
At least I had the voucher, so now I'm only paying full price for the exam
