good luck last time i tried (and failed) the test had 50 questions, from the $400/$500 question (not the $100 easy ones!) if you've been watching, you'll recognize about 10% of the questions, (others are old, old, older...)

PS: look of a seat marked (on back or front with J, for jeopardy, or A for alex) --and sit there...not telling you why but do it!--there are often 2 or so per bulk auditions.
