Seeing as I passed the test 2 weeks ago, but got rejected, I'll concur with the others in that I did not present myself as well as I would have liked. I'm gonna try to change that if I go to a taping, but if nothing else, yes, be excited and make yourself look interesting.
If nothing else, I'll at least give you the particulars of the test. 30 multiple choices in 10 minutes. They'll give you those good ol' Scantron sheets to mark your answers. I've taken that the difficulty is pretty decent, you're gonna see a zinger at least once every 4 or 5 questions, but it's not too bad if you're well read... and well up to date on your Millionaire. I found a question last time that came from a Millionaire episode, and I only know that cuz I ran into the question when scanning tapes the other day.
But overall, if you pull the standard quiz fare and cram with some Millionaire, Ben Stein and Jeopardy, I'm sure you'll do OK. Whether it'll actually come up is one thing, but at least you'll have enough to make some educated guesses on. Trivial Pursuit cards are good, too.
OK, I'm done with the cliche strategy now. Good luck! Let me know how it turns out.
