- dot point summaries modelled on the syllabus.
- past papers (as many as you can get your hands on) and trial papers to get familiar with the style of questions they ask.
- ask questions - to teachers, tutors, friends, peers - because it may come up in the exam!!!! and you don't want to be sitting there wanting to kick yourself so make sure you understand the concepts and how to apply them. if you make a silly mistake, remember what you did wrong so it won't happen again in the hsc.
everyone has a different study technique but those 3 golden rules are a must for all subjects, not just physics. maybe borrow a few textbooks as well because they all vary a little and one may explain things better than the other and you also get more examples and questions which is a bonus.
