JB and LTD,
Relax guys. You'll do fine. I was in the same boat, I walked out of the sim prep with a pretty low bar set on my performance standard, I have zero transport time like you guys though. Did the interview the next day, and I don't know what it was but it was like the heavens opened, angels sang and the sim just.... worked. Or it was just a case of a blind squirrel tripping over a nut. Either way, the prep had sunk in over night.

Just memorize what they send you, this can't be over stated enough. Then chair fly it, over and over. About 6-7pm the night before the interview, stop looking at everything and just get a good nights rest. Lastly, have fun... seriously. Your mood in the box will effect how the entire evolution goes.

Good luck!
