Make sure you fully understand the content, rather than merely rote-learning it, because although you may be asked to spit out definitions, you will also need to be able to apply your knowledge for a lot of the questions.
Once you think you've understood the content well enough, do some practice questions. What I usually did was questions off a study guide (such as Neap, A+ notes, checkpoints, etc.), but if you don't have any of these, then a more viable (and valuable) option would be to go to the VCAA past exams section for psych from 2002-10 and print off the relevant questions, as these are already divided into AOS, so it saves the trouble for you. I can't remember if some of the topics weren't tested back then, so maybe someone else who remembers can help you out here.
Good luck and if you need any help feel free to PM me
