I'd add "make lots of notes" - you can read up notes online that others have made (I can share mine if you like) but the process of writing them down yourself goes a long way in helping remember stuff. Keep going over the notes until you have them coming out of your pores
Go all out on mock exams - none that I took (incl Whizlabs) came anywhere close to the difficulty level of the real exam, but it does give one an idea on what to expect.
Best of luck
