I agree. There is definitely more bio than ochem. I had FM form.
The changing trend I noticed in my form was that there were lot more independent questions for Bio part that relied on previous knowledge than knowledge from the passages.
For ochem, they didn't expect you to memorize the frequencies for IR and NMR. (although I would still know them). Previously, the expected you to know all the frequencies..like the IR peak for ketones is usually around 1650-1700 cm-1. These frequencies are usually given in the recent MCATs. MCAT emphasizes mechanisms a lot in ochem. Well, I thought the emphasis was more this time than usual (at least in the passages I got). Also, I would recommed knowing the different tests that are used for determining the kind of organic compounds.
good luck on ur MCAT.
