Preparation

Although I haven't explicitly been told to read or not to read anything before the course, I don't think it can hurt just to get a general idea of the British legal system before I go, seeing as I've never done any study of law before.

At the minute I've looked at:
Learning the Law, Glanville Williams
The Law Machine, Berlins & Dyer
SWOT: A-level Law, Johnson et al, and
A-level Law, Dugdale et al

Out of these, I'd say that the second and fourth ones are the most accessible for 'casual' reading, whilst the first one seems like a useful reference text as to how to approach legal study.
