Yes, I took it in January. The best way to revise is to practice old papers so that you know how to carry an arguement (for the essays anyway). Also I would recommend reading the papers and paying attention to the news - quite a few of the questions always seem to have some relevance to what is happening at the moment. Languages and Maths - just revise as if you were doing that subject, although there is actually little maths in Module 4, it is more understanding spacial relations (e.g. what something would look like if you folded it a certain way), basic scientific principles and working out how machines would work if a certain cog turned a certain way. Hope that helps.
