thank you for the advice...I know it's not what works for everyone else, that it should be what works for me, but even so, I don't have very good study skills as far as WHAT to do during any period of studying.
Okay, let's see if I can help.
1) Understand the material. Don't just read through it again and again. Actually understand why things happen. If something doesn't intuitively make sense to you, and you don't think it was explained well, see if you can contact one of your pre-req instructors or a learning center or something.
2) Do questions. Lots and lots of questions. At first, work through them without a time limit, trying to get to the correct answer. Do 5, 10 questions in a row, then stop and go over the answers. Figure out why you picked a certain answer. One of the keys to being able to use practice exams (multiple choice ones, anyway) is that if you're studying properly, you should be able to not only explain why a certain answer is right, but why all the other answers are wrong.
For instance:
An increased intracellular concentration of which ion will result in an action potential.
A) Na+
B) K+
C) Cl-
D) H+
The correct answer is sodium, because sodium depolarizes the cell (makes the membrane potential less negative). Letting both K+ and Cl- into the cell will result in hyperpolarization, and thus will prevent an action potential. H+ has some effect that I can't remember off the top of my head, but by itself will not trigger an action potential either.
And yes, there's a lot more to it than that, but you get the idea.
3) For the questions that you missed, go back and review the material, even if you understand why you got wrong after you review the answers. It will help make connections for you.
4) If you get frustrated, walk away. Come back 20 minutes later ready to start and look at the material with a fresh mind. Take a day off per week and do something unrelated to MCAT studying. You'll thank me later.
