Just for reference, here are the acronyms I use for different study materials:
- EK = Exam Krackers
- TBR = The Berkeley Review
- TPR = The Princeton Review
- 1001 = The EK series of '1001 Questions' books
I also have all the Kaplan books, as I took Kaplan many moons ago.
So which ones do I like? Well, that depends on your skill level. This is how I'd rank them according to 'explanation vs. your knowledge' of the subject:
Kaplan << TPR <= EK <<<<<<<< TBR
still in college-------------------------------------master of material
When I was studying for the test the first time, I had graduated college 10 years prior. And I didn't even have the full year of physics- I was a quarter short. In fact, the last time I had taken a physics class was 12 years prior to opening any review book. Needless to say, all the material was Greek to me. (Or was it latin? I forget my dead languages.)
So Kaplan worked very well for me for my first go-through. I think it goes more slowly and more elementary than the other books I've used. But I think because it is so basic, it doesn't really lend itself to a score higher than 11 or so. It also doesn't have a lot of in-book passages, just basic questions. The online questions are also discreets*, so you don't get a lot of "MCAT" practice, just practice of your knowledge. If you did fairly poorly in your undergrad science classes, and/or didn't learn the material, start here.
*Discreets are questions on the MCAT that aren't associated with a passage- there are about a third of these, compared to two-thirds of the passage problems. Hell, maybe there's even only a quarter of these, hence the need for *passage* practice.
But if you're one of the lucky ones who actually did study and learn the sciences (*cough gunner cough*) then I'd suggest either TPR or EK. These assume you know a lot of the basic principles behind the science, and it builds on top of the knowledge without explaining it. For example, I was reading about aromaticity this weekend and wanted more review, so I had to go back to my textbook since it wasn't explained in depth. EK has lots of discreet practice problems (1001 to be exact) as well as mini practice MCAT exams at the end of each chapter. I haven't taken the online TPR class, so I can't comment on their online material, but I like their books.
Finally, if you're sitting pretty with a strong grasp of the material, spend most of your of time on TBR. These books are *hard*. I got all As in my physics classes, but nearly bombed the first chapter's problems. These books will definitely ensure you understand the material, and these give you tons of true-to-life MCAT passage examples. I plan on spending at least half my time with these books. They also sell online practice MCATs- I may be getting some of those as well.
Finally, don't blow off the verbal section. EK has the best practice for these, 101 Verbal Passages. This section apparently is pretty important to schools, so learn the tricks for reading the passages and how to parse down the correct answer. It isn't just reading and picking out the right answer- the MCAT questions are way more irritating.
Bottom line, you need to chose a set of review books that is at your level- if you are shaky in the material, TBR will make you feel like an idiot and you'll quit (not that I'm speaking from experience or anything. ahem.) If you are a PhD in electrical engineering, Kaplan will give you a false sense of security (and probably a god-complex too.) All of these can be expensive, but they'll be worth it. Just don't go borrow the 2008 version of Barron's at the library- you'll be sorely disappointed with your score.
