I am somewhat confused. I am trying to save some money by buying used MCAT books, but I don't know whether the material is going to be the same as in the newer editions. I am mainly talking about TBR and EK, which are 2003-2004 editions. Do these books ever get old? I mean the material on the MCAT is still the same anyway, right? I just don't want to invest too much in new books when I already have at least one (or two) years before I take the MCAT. I understand practicing the new MCAT CBT format, but beyond that, the material seems like ought to be the same. So what do you guys think? From what I have seen on amazon and talked to TBR, it seems that these books are already 2002 edition anyway! What do your books show as the earliest date in their cover? Can we compare them and see what everyone has? I have a chance to buy all TBRs (2003-2004), Kaplan (2007), EK (2003-2004) for about $100 and I'm thinking maybe I should go ahead. But if the MCAT material is not well reflected in these older books, then it is just $100 wasted. Any inputs?
