as another poster and i both said, exam experiences depend on what actual exam you took. and tons of other things that relate to the candidate.
the way i looked at is this:
CARs is its own section. not sure you'll do that much better with alot of studying. others will disagree. maybe you can game the exam a bit.
P/S is pretty easy to learn, although i didn't know it well enough for my first exam. my memorization (not "knowing how the pieces fit together) was not good enough...... i would recommend a MEMORY COURSE to people. after all, you are trying to get a good grade on exam, not really understand the material. at least NOT P/S
that leaves 5 hard science areas (and i'll describe what i recall vis-a-vis Kaplan chapters)
biology - A) i think the earlier 12 chapters were cells, genetics, virus, bacteria, B) later chapters were pshysiology. i don't think you need a professor to learn this well... i don't remember a 3rd section of book.
chemistry - even though it's 3rd most important subject, you need to know all of it and very well. the questions they give you would be simple with an open-book (not true of other sections)
OC - first couple of chapters (chirality etc.). know these...... late chapters: measurement - very important, easy to overlook... in-between chapters aren't that important. even the study services say de-emphasize these.... this is something a professor would be very helpful with, but it's not that important. you can learn early chapters and late chapters with practice Q's. middle chapters are a big pain, but not that important.
physics - know it all. not that hard to learn. don't leave to last minute if you don't know it. big mistake i made.
biochem - amino acids, enzymes early chapters really key.... late chapters = energy cycles. seems like it would be important, but i thought it was pretty light... can't remember what the middle chapters were. carbs, proteins, fats??.. if i don't remember what they were exactly then they probably weren't important.
so for me, THE EXAM basically comes down to the cell/virus/bacteria/genetics from biology and amino acids/enzymes from biotech.. if you know these well, then put alot of emphasis elsewhere, but if you don't know these then concentrate here.... also, anything measurement related like tests (chromatography, spectroscropy sp?, units used). make sure you know those.
