erjdriver,
It may well be worth your while to attend the brush-up if at all possible even though you are exempted. On the course you will receive enough practice papers till they're coming out of your ears, as already stated, of a very similar ilk to the actual final papers. They really do just push you that little bit further to ensure you are right upto speed for the exams.
You also receive the benefit of obtaining the latest feedback questions from the exams, invaluable in my opinion.
all the best.
