You should start by going over the specification to see what you'll be tested on. You should learn any statistical tests which may come up. You'll need to revise the various things which will come up including how to analyse tables/graphs for correlations (which does not mean causality). Then the obvious targets for revision include independent/dependent variables, controls, placebos, experiment conditions (minimising variables), fair trials, that sort of stuff.
