fill in the blank on the memory items and limitations they send you.. My packet 3 years ago had a sample test in the back.. or it may have been a copy with the relevant items highlighted.
it isn't pass fail.. it's feel like you are prepared or feel like a schmuck. You and the guy sitting next to you who corrects it and the instructor who collects them after are the only ones to know how you did.. and as long as you make a halfway decent showing noone will say boo!
Caveat.. it's been 3 years since I took it....
