This is what worries me about attending medical school. I'm much better at understanding how something works, and not just memorizing a list of facts. In fact, I have a hard time memorizing facts unless I understand the mechanism. Anybody can google a fact or can look it up in a book, but it takes somebody who's learned how the body functions as a whole and about pathological conditions to determine the treatment plan for a patient. Frankly, I don't understand why they hold to the memorize, regurgitate, forget model as you will be needing to understand how the body functions when you are practicing.
Some of my friends call this the penguin analogy. There's only so much room on the iceburg, so as new penguins are crawling onto one side, a few penguins necessarily have to fall off the other side. The profs go over the important stuff many times and in various forms, so it's not like you learn how to recognize a systolic murmur and then flush that info down the toilet. Those penguins get like, superentrenched or something.
Learning "how the body functions as a whole" sounds like it came right off your personal statement (no offense intended because it was probably on mine somewhere too). That statement drastically oversimplifies the
huge body of knowledge that even the fire hydrant/mental bulemia approach to teaching/learning isn't sufficient to cover. There's simply no other way to do it. One just has to go through it before having any chance of getting out on the wards and actually treating people.
Your particular learning style will help in some areas (phys for example) and hurt in others (anatomy). Regarding the OP, I worked full-time throughout undergrad, maybe crammed in the nights leading up to an exam, and came out with a 3.8+. If I did that now my scores would be in the teens. The pace and volume is grossly different; we go through a college semester's worth of material in a single block, with 6-10 blocks per year. Somebody above mentioned the manner of presentation, and to me it's just the reverse. Profs throw out the vocab, stats, and mechanisms left and right. You have to go home and relate it to disease processes and pathology, then integrate it with everything taught before and after (our exams are comprehensive). This may well be easier for engineers, because they're used to learning the building blocks and doing whatever with them, but for a spoonfed bio major...
What's easier for me is finally being able to see the light at the end of the tunnel. Plus there's no longer any question of, "When will I ever use this?" because you will undoubtedly have to use it very shortly, if only not to look like a ***** on rounds. Compare that against forcing yourself to memorize all the intricacies of SN1 vs. SN2 rxns, or trying to care enough to learn how Mayan architecture influenced early American art. What's also nice is being able to set my own pace (from home vs. attending lecture, textbook vs. lecture notes, etc.).
