Pretty much your preliminary legal exam would contain the first 8 topics of the preliminary course and the 2 option topics that your school does for legal studies in year 11. Those notes up there cover the first 8 topics, but for your option topics in legal studies, they would most likely be the ones that will be covered through an essay or something like that, well that's what was in my preliminary legal exam last year anyway.
Basically, just find out what your option topics are, then review the first 8 topics as outlined in the syllabus and then look into your two option topics and study them in depth, because they will usually be the ones that are covered in the exam in essay format.
