Try to understand how the current topic links to the past/previous topics. In your notes break up the lecture into sections to decide what the overall big picture is about.
Also try to avoid capturing raw facts. These are of no help to you on the exam. Always aim to write detailed notes so you can use them to study in swotvac.
I don't know about you but i'm a visual learner so just reading notes no matter how simple won't do for me. So whenever I get a large friggin stack of lecture notes from my lecturer, the first thing I do is make a concept map and connect all the ideas together, but doing concepts are good for learning the basics (I mean there is only so much that you can learn from a concept map, they're meant to be simple) but not for a whole lot of detail. So I simplify the really detailed stuff into my own words and draw pictures to go with it......
*note this obviously wont work for math

just practice practice practice.
