Once again, break everything down into being either conceptual things, or things to rote learn. For conceptual things, if you don't get it during the lecture, make sure you note that and go home and read up on it within that week from a textbook until you understand it. For anything which needs to be rote learned, write notes (e.g. anatomy/pharmacology will need this) and revise these regularly, or cram them just before the exam if you prefer that approach. One of the top students in my cohort is known for her (excessive) use of flash cards, so you could try that as well. Personally I'm a bit too lazy for those though. The exams are almost all multiple choice at Monash, so you don't really need to memorise anything perfectly anyway unlike VCE. A rough understanding of everything will get you by a MCQ exam with flying colours.
EDIT: Actually on second thoughts, DO NOT CRAM ANATOMY. That is about the only subject I tried in on a weekly basis. Everything else I crammed before the exam, but for anatomy, actually bother with pre-reading to get the most out of every tutorial. With this mentality in mind, it'll make sure you keep up to date. Otherwise it's very easy to fall behind.
