I took that!  If you are good in math, it really is not that difficult.  I
have friends who had a hard time with it, but they always struggled in math
in school.  I think the question you posted would have been one of the more
difficult on the test.  Just remember not to get hung up on any one
question.  They are not written in order of easiest to most difficult, so go
through and answer the ones you know, then go back for the rest.  When do
you take the test?

You probably are.  The day I took the test I was pretty freaked out, too.
Mostly because all I had used to study was the guide they gave us, and when
I got to the test site, I saw all sorts of people frantically going through
their Cliff notes study guides.  It hadn't occurred to me until then that
any real studying might be required.  I though it was a test of basic
knowledge.  But I ended up passing with flying colors--because it reall is a
test of basic knowledge.  And it isn't as if you have to score in the 90th
percentile to pass.  But it is good tyo be a little nervous--keeps you on
your game.  My biggest piece of advice it to make certain you have plenty of
sharpened pencils.  When I took the test, about 1/4 of the people brought
pencils that were not yet sharpened, and the university where we tested had
no sharpeners.  So they all stood in line to use the little, hand-held
sharpeners brought by 4 or 5 people.  <chuckle>

What grade level are you planning to teach?
