@DocBBear First off, congratulations on your exceptional MCAT scores; they are really an impressive accomplishment! Second, I agree with @ridethecliche, despite being a standardized test, there is a substantial amount of variation between testing administrations. It does not surprise me at all that some tests are more organic chemistry intensive others more physiology intensive and still others biochem/mol. bio. Nevertheless, I reaffirm, based on all the AAMC practice exams, my own experience, and my students' experiences, that the MCAT tends to emphasize biology over organic chemistry. This is not always true but is a general trend.
Second, until this thread, I was unaware of the general sentiment that the biology section has be substantially "revised" in the last two years without AAMC informing anyone. That would be an alarming thing indeed. My view of BS, as with the entirety of MCAT, is that doing well depends on a balance of background knowledge, critical thinking skills, and time management. Undoubtably, some passages will require more rot memorization and others will emphasize critical appraisal of passage information. I think that is well reflected in the practice exams. Our books, and really any good MCAT prep materials, include a review of the high yield, foundational knowledge followed by passages that apply it in novel ways. Some passages are easier than the real thing while others are substantially harder. I think they are a good if not perfect preparation for the exam and many students have used EK and gone on to do very well on MCAT BS.
I do not have time nor am I eligible to take the MCAT again. I will start medical school in the Fall, which will become my full time responsibility. It's a good recommendation however
