I forgot to reschedule this one and hadn't put any time into studying for it, so I was less than optimistic about a pass. I basically just went to fail, so I could use my second shot. The test is split up into three timed sections for each exam, and my understanding is that if you fail one section, you fail the entire exam. The first section was only nine questions. If the questions are all weighted equally, that only allows you to miss two and walk away with a pass. I thought I might have gotten four or five right, so I just burned through the rest of the exam. Needless to say, my results caught my completely off-guard:
70-640: 820
70-642: 887
70-643: 730
Uh, what!?

The questions were all over the board. One would ask you something like which corner is the start button in by default and another would be some really obscure command-line procedure. I can't believe I spent $200 on the Transcender exam and never even used it...
Oh well, on to 647 I guess...
