Here is a Portable Document Format (.pdf) version of some revision notes I made for myself for the January 2009 AQA Module 2 Biology Higher Tier examination. It covers all topics, perhaps not to the detail required for your own personal understanding. Note that these were not designed with general use in mind, but I thought I might as well upload them after I had used them. There may be some mistakes with the English, but there should not be anything wrong with the actual science. Finally, my apologies for the low quality of reproduction during conversion to .pdf. Contact me for the original Microsoft Word 2007 document, which is much larger and cannot be successfully converted to an earlier version of Word Document - believe me, I've tried!
