Here's a bunch of blahblah on what seemed to work for me. Maybe it'll help you.
Taking my own notes on the lecture notes (recopying the major info, graphs, important tables, restructuring and reorganizing the info in my own way) really helps. Then I never go back to the lecture notes again--I just read my own notes over once or twice and it goes in easier. For this to work, though, your own notes have to be rather complete, but if you put in the time with each lecture really understanding the major concepts and writing out the important info/relationships, it might work well for you.
Different "sources" is also key for me--not so much for doing well on my own school's tests (cuz they mainly test from their own lecture notes/syllabus), but for actually learning the medicine... There are tons of websites out there, including emedicine.com, wikipedia, library resources like statref or Harrison's online, etc. I know, wiki is pretty ghetto and wouldn't stand up against medline sources in class, but it's great for quick info that will help you make new connections in your brain and form a new understanding of things. A lot of times you can just google things too, and find websites of OTHER med schools that deal with the same topics and often, their professors are better/more organized than yours. For me, understanding the basic concepts is really key--and all the memorization is easier after that, because you can reason through why certain tests are elevated and all that.
For sheer, stupid, blind memorization, try making up dumb little associations in your brain. For example, I remember that Wilson's DZ is a 13th Chromosome mutation by conjuring up this dumb*ss, ridiculous image of the guy from Friday the 13th (Jason) playing volleyball with the ball from that movie where Tom Cruise was stuck on a desert island (Wilson). In my brain I can't separate these two concepts even if I tried, because the relationship is so outlandish and completely stupid. Another example of sheer stupidity: an underwater sweet-16 birthday party for a teenage fish (alpha globin locus is on chromosome 16). FerriTIN is the storage form of iron because you can put stuff in a "tin." Or, trazaDONE is the antidepressant that can give you a "boner" (priapism) because that's idiotic and it rhymes. I know, these are really the kinds of things you'd want running through your doctor's mind when he/she's thinking about what kind of antiarrythmic to give you when you code... It seems to work for me, though.
Now you know the secrets of my crazy, lunatic brain. Use them wisely.
Good luck to ya.
