Have you tried completing any practice questions? Busman is more about application than memorisation, and for most questions, you can even use common sense. If you want to do well in bus man start with completing your notes using a range of resources such as your textbook, TeachingBubble and edrolo. Then make flashcards for your definitions, which are very important (don't worry about memorising exact definitions, just ensure you have the keywords - check past VCAA assessors reports for these). Then start doing practice questions open book, then try to do some half open book and half closed book. Eventually, start doing them closed book. Also try to do timed questions, because busman SACs tend to be short on time - to ensure you receive the best possible mark start with the larger questions if possible e.g. 6, 8 and 10 markers.
