Obviously you've never taken an MCAT.
-The MCAT is not about tricks; it's about testing your critical thinking and problem solving abilities. Those that aren't prepared for the MCAT will come out of it claiming that it's nothing but tricks and traps, but only because they did poorly and know it.
-Study well, get a review book that you don't have to wrestle with in order to get the information to stick(I, for example, found that Kaplan and I didn't get along, but Examkrackers and I were fast friends) and be prepared to face your own problem solving abilities. No, the MCAT doesn't test knowledge in the conventional way that you're used to in undergraduate, where they ask you a question from the text that you either studied or didn't. Knowing the material for the MCAT isn't enough; you have to know how to manipulate and navigate through a data set to come up with:
1)What the question is REALLY asking
2)How to solve it
3)What info is necessary and what's extraneous.
Take a couple of practice tests. See what you get wrong and why. I'm betting you'll find out that you don't miss questions because they were "tricky"; on the contrary, you'll probably find that you missed a question because you didn't fully critically think your way around a problem.
