As I said in the other thread, there's a lot of human biology and some psychology and a little bit on sociology (which looks at history of health development and research).

On my course, there was much more focus on biology - with around 27 credits out of 45 devoted to it. There was only 6 credits for sociology and the rest for psychology.

I'd recommend reading up on biology towards the start of the access rather than now, especially cell structure and enzyme function.
Psychology is hard to get your head around, but you can learn that as you go along (same as sociology)
