I have taken the in class Kaplan course during last summer and took the August MCAT.
I truly think that the in class course was useless while the online resources and the books were helpful. I believe you can purchase the online resources and the books (as an online course) rather than the in class course. What they go over during the class isn't the material you need to know for the MCAT. Rather, Kaplan goes over their "strategy" in passage approach by "mapping" the passages. "Mapping" briefly, with several words to a short sentence, summarizes each paragraph of the passage. I found this to be incredibly ineffective. In my opinion, if you are finishing the sections at least 5 minutes early (if not 10), you can not "map" the way Kaplan wants you to and finish the sections. The bottom line is that Kaplan in class lectures are not going to teach you the material you need to know for the MCAT....at most they'll go over about 10% of the stuff you need to know. You are supposed to have reviewed the assigned reading before coming to class. So that while you are IN class, they go over the Kaplan strategy using A FEW of the topics you read.
Again, the online resources such as practice tests by Kaplan and AAMC were nice to have. The online quizzes and topic tests were nice too. The books and the flash cards they send you were decent. With the in class teachers, it's hit and miss. My physics teacher was soooo wrong about some of the stuff...because she doesn't know physics! On the other hand our ochem teacher was good. So, it really depends on the teacher.
Lastly, the money back guarantee by Kaplan is incredibly difficult to get since you have to do all of their quizzes and tests.....there's a LOT. You will not be able to do them. Plus, the higher score guarantee is kind of B.S. since the diagnostic test is designed to be incredibly hard so that you most likely are going to get a higher score on the real thing unless you pass out during the real test and forget to void the exam. (you need to score lower than the Kaplan diagnostic test on the real test AND have done ALL of your quizzes/assignments etc.... to get your money back. I'd say it's nearly impossible to get the money back).
As someone has suggested, buy the review books...EK, Kaplan, PR...they will I'm sure all do good jobs.
Save yourself the $1600.
