@Bobby, I can relate to the tech troubles, although your situation sounds far worse!
From my experience during the FAR exam earlier this month, I expected the computers would be slow and especially glitchy during the sims. That was definitely the case, but this time when I clicked in a particular cell of my 5th simulation, my computer froze entirely, requiring a reboot. Center staff couldn't get the exam to reload on the same computer, so I was moved to another, where it restarted and again froze when I clicked the next cell I needed to complete.
While I was waiting to for my 2nd restart (after deciding my only option was to go onto tabs 6 and 7), a staff member told me they had a lot of equipment replaced two weeks ago. He said ever since then, the exams in the room I was in were freezing. According to him, "it's only the CPAs." I was astounded that they continue placing CPA candidates in this room, when the place was at around 50% capacity and I could have easily been assigned to the room where CPA exams don't freeze.
Anyway, I finished, just skipping the one bit. I prepared with Becker, and there were definitely some things I was unsure about.
@Tran - I feel the same. Just as unsure as I was after FAR.
I'm sending positive thoughts to you all!
