Ok, so I want to start studying for the MCAT early, because when I was skimming through SAT studying, I noticed kids started studying for it in 6th grade. However, I'm kind of confused as to how I should do it. I want to teach my self, so I plan on buying a bunch of books and just go through them when I have free time during college, but idk where to buy the material from. I've heard of Kaplan, Princeton, and Examkrackers, but when I was studying for the SAT, I remember people saying that the Kaplan and Princeton books were worthless because only the Collegeboard knew how to make ACTUAL SAT questions, and to just buy their blue book. I'm just wondering, is this the same case with the MCAT, or are the princeton, kaplan, and examkracker books good review?
