Since you are playing College Bowl, I believe,
there are plenty of hints on the College Bowl website,
especially in the "Coaches Handbook," just as, if you were
new to NAQT, downloading their "new writers' kit"
gives some insight into the psychology of THEIR
questions.
At some point on their website, College Bowl does,
or did, list common sources used for their questions
and their question distribution (snicker all you
want, fellahs; they actually do stick to it, they just
don't define things the same way as everyone else).
