I'm about to start studying for the MCAT (2nd attempt) since my old scores have lapsed. I have a 5th edition (2003) set of Examkracker text books and was given a 2006 printing of the Kaplan course books. I was wondering if the content of the MCAT test has changed substantially enough that it would warrant buying new editions (Particularly the Examkracker books). After looking at the info. supplied on the AAMC page I'd suspect the answer is no, but was wondering if anyone who has seen the newer editions of these texts would think differently. Thanks.
