I did mine recently, however this thread rather intrigued me.
As Mr Keshy mentioned, the compare questions are tough. I recently had my sac and on it was an eight mark compare question. The compare questions are tough. however, I feel that dividing answers into paragraphs helps a lot and allows your teacher (and at the end of the year your assessor) to easily follow your response and see what you are saying.
Yeah, I generally separate my paragraph based on the mark structure, and the wording of the question. It's easier for me to proof read too, just an added bonus.
Because for example, in a three mark question. The teacher could be looking for the definition of a management structure, the type of structure itself, and an example. So if I separate each part into paragraphs, it essentially means he can read each paragraph and theoretically, tick each paragraph as a mark. And if I wanted to argue a point after receiving my marks, again, there's an added bonus of it being easier.
