My school, Samford University in Alabama, required either the GRE or MAT--I'm sure other schools
will also accept either exam.
If you are able to take the MAT it is basically like a word puzzle- figuring out A is to B as C is to D, or A is to C as B is to D. Some of the analogies are "backwards" - C completes A.
I did not take a review course or really study, but I did look through one of the review books.
The advice in the book that I really found helpful is plan to make 3 passes of the test.
Make one pass and fill in every answer that you are sure about.
Then make a second pass and spend some time on the questions that you weren't sure about the first time- also, the second pass you will see some answers you didn't the first time.
The third pass - when the proctor announces there is 5 minutes left (or maybe it was 10--can't remember) go thorough and fill in circles on any question you can't answer-you can just fill in your favorite letter-the test counts only the correct answers, so there is nothing to lose by guessing.
