try a search. plenty of material to read and some gouge. check it out.
my take was that the books pretty much covered all the types of subjects you'll have, not necessarily the specific questions though.
another big thing i noticed was the timed portions. the spatial perception i believe, identifying the aircraft orientation based on the cockpit view, had to be completed in 5 mins or so. i figured out how many seconds i could spend on each one, answered them and moved on, so i didn't end up with questions unanswered. other times you oughta have plenty of time.
check out all the other material on the board. unless you've already done that. in which case, good luck.
