For all you brainiacs, students and geeks...

There is also the physiology colouring book.

I realise there are assigned books, however, picking up a really dead easy overview of the topic, or doing a search on the internet for things like haemoglobin dissociation curves (or whatever it is you have a hard time wrapping your brain around), and finding really easy write-ups or cartoons, makes it so much easier.

Mr.Plunkey has awesome suggestions.

I would also recommend re-writing the notes you take in class that evening.

That is great advice. Always worked for me, and I freaking hate studying.
