I'm a reader. When I "try to memorize" things, I feel like I'm just wasting time. I tend to get a lot of the conceptual stuff on the first pass and do well on some of the tricker test questions that require a deep understanding and application of knowledge, but then miss a lot of the "easy" questions that are just rote memorization (what artery goes here...). In the end it evens out.
For step 1, I've pretty much stuck to that, but increased the reading to cover a subject multiple times from various sources (i.e., neuro from FA, RR, HY, class notes, CNMRS, etc.). Sometimes I pick up something new I didn't know, but mostly it's for the repetition... seeing the same thing worded a different way, and hoping that more of the details stick.
UW has helped a lot for some of the micro and pharm details that would normally not stick at all, but I swear I can't remember what novobiocin vs. optochin vs. bacitracin differentiates more than an hour or so.
In addition, I have actually made a concerted effort to "memorize" pharm, since there really isn't any better way. 🙁 I still forget a lot of the details, but hopefully enough of them will stick until after the exam to not hurt me so much.
