Yeah - my mistake - I was getting it mixed up with my Biology, which is on the Thursday, sorry! :doh:

Don't worry. This Biology paper, is it AQA Unit 2? I have that Bio paper next thursday.

Tip for you guys that are taking this exam... you have to do as many application questions as possible. Trust me, the past papers of the old spec does not gear you up for the real exam.
