HHD was such a long time ago... don't remember my first SAC

What topic have you just completed? I might post some notes for you.
Well, you never really know what to expect on a SAC
exactly (other than the topic you've studied...), so first of all (although this is an obvious one), I’d recommend going through your notes thoroughly and memorising as much as you possibly can. I don't think it's necessary to know every risk factor for various diseases, but it’s imperative that you are able to explain a couple in significant detail. It's important to understand most of what you've learnt so far.
Have a look at the HHD outcomes for the topic you have just concluded, and make sure you are able to answer/ do each of them in a reasonable amount of detail. This is what I did after we concluded each AOS/topic, and I’d write up a couple of paragraphs on each dot point, and then check my answers in the text book or notes. You'll need to know this anyway.
If there is any particular thing you are having difficulty with, feel free to PM me or post here, and I'll try and help you out.
