How to begin revising for GAMSAT?

So currently I've just finished my first year of uni, and i'm going to be applying to Medical school in sep '16, 2 of which require the GAMSAT, I'm studying Medical Physiology and have a levels in chemistry and Biology but no physics background post GCSE. I'm just wondering what resources and revision guides I should be using to get a high mark in the GAMSAT? I've recently taken out the GAMSAT gold standard book from the library and plan to start revising from this, would you recommend me buying any additional material on top of this? I'm going to be applying to Nottingham and SGUL in case you're wondering :)
