Another tip is to get a pocket notebook and, as you're going through the notes, make a note of any useful formulae, mnemonics, facts etc. Then you have a condensed form of the subjects for quick revision. I also did a similar thing with the question banks.
Ian, the OP is likely a modular student with a PPL since Bristol only does distance learning and not ab-initio integrated courses.
