I was able to take my exam the next day.
Aw man, you missed your test!? That's too bad!! :-)
Yea, when I took my test I had to schedule it with Prometric, go in to take it. The exam itself was probably 2-300 questions and they gave us 5 hours to take the test, luckily it didn't take nearly that long, but definitely well over an hour for me to complete it, probably much closer to 2. Didn't feel too bad though, some people said it took them 3 - 4.5 hours!! Of course it was the SCP Beta exam before they whittled the questions down and brought out the real thing!!
