I'm in a similar situation, ie. don't need approved course. Bristol offers all their notes on CD for 350 pounds. You can also buy the printed notes seperately with no brush up course for 1100 pounds. I figure you can do a lot of printing for 750 pounds!
The brush up courses cost around 400 pounds for each 2 week course if you want to do these seperately. Considering the exams cost 80 pounds a pop to write, plus accom and flights in your case, it might be worth considering doing these.
