Same as usual, study and revise the content well. Just don't forget the stuff you learn in Unit 3 by the end of the year (easy enough, just practice every now and then).
Same as usual, practicing exam style questions throughout the year would be handy, don't just work solely out of the textbook and leave your first introduction to exam type questions to before exam period. There is a large difference between what textbook questions try to get you to do (learn the concepts) and what the exam questions get you to do (apply/test your knowledge). Assuming you're doing Unit 2 physics currently you should be able to look at Unit 3 motion questions from previous exams and see the difference yourself.
Same as usual, pay special attention to VCAA exam questions, regardless of study design, the main difference in this next study design is that you do one detailed study throughout the entire year and the exam format. As indicated by the
exam specifications document, the style of questions is pretty much the same as this study design. You
may find that, being 2013, you won't need to go back that far at all in terms of study designs.
Same as usual, practice your exam technique and exam timing skills. Only this time make sure you have an attention span where you can sit still and focus for a 150 minute exam.
Same as usual, focus on understanding the concepts as well as you possibly can.
