I can't guarantee that this is the most efficient or effective way of memorising large sums of notes, but what I did (and still do mind you) was trying to make everything visual. For instance, drawing up a flow chart or visualising the content and putting it into a story. I felt that was most effective for me but obviously, some things are hard to remember using this technique.
Really depends on you...
My teacher told me to stick up notes on the sides of your bathroom. So when you take a piss or something, it'll remind you of your notes.
I just recite it like telling myself a story, it'll stay in my brain for about 2-3 days.
