@astewart – The Miller Analogies Test (and similar tests) aren’t prepared for in the same way classroom tests are. Though it’s obviously a good idea to study, there’s less of a “correct” way to do so, and unlike classrooms tests, you’re not expected to know every answer.
If you reread the article, it even says that only 100 questions count toward the final score, even though there are 120 questions total. As some final advice, don’t spend too much time on questions you don’t know, skipping them if need be. You can always come back to them later.
