I did it this year so study score not out yet, but our teacher gave us pointers constantly throughout the year due to him being an examiner himself.
How harsh and specific are examiners when marking the exams? They're looking for key points and features for most of them. Some are globally marked. For example, the definition of sole trader needs to have "owned and operated" or something that conveys the exact same meaning. "The examiners are trying to be on your side" is something that he would always say, but idk if it's true.
Also does including examples and contemporary case studies in your answer essentially give you more marks? From my experience with SACs and practice exams, not exactly, but having case studies would allow the examiner a better grasp of what you're trying to convey in your answer. But if a question is a part of a case study (even if it's not part B), you should always refer to it however you can.
What is the best way to tackle the 10 marker? Should you do it first? My teacher recommended doing part B of the exam first, then part A in however order you prefer. The best way to prepare for the 10 marker is to do a lot of practice ones, and
get feedback from them. Also, do some separate from your prac exams, but others in combination as that gives you a good grasp of time constraints.
Finally, what our some crucial tips for a 40+ study score? Not sure myself because I have to wait until 30/12/20.
