AAT Member - wanting to refresh knowledge

I completed my AAT Qualification back in 2008 and whilst I have kept up to date with my CPD I feel that there are so many areas that I would like a refresher of!
Any ideas on the best way to do that? Buy the books and re do them? Past Papers??

Are you MAAT and have you kept up to date with your membership fees? If this is the case there is a lot of CPD and information on the members pages on the website.
Branch events are also a good source of CPD.
