https://eiewebvip.edexcel.org.uk/pastpapers/. According to Edexcel it's results day in March, and so long as you know your centre number you can get hold of them. Though having said that, using my centre number I can't even get hold of the June 2008 mark schemes or papers.
Between the amount of exam papers Edexcel (and most, if not all exam board sites in general) are actually missing and the fact that they actually charge you to order their past papers (when you could get them for free and print them easily at home!); they're all pretty useless online.
Guess i'll just have to wait a week (i think it's a week)
Still, i wouldn't say no to a sneak peak before then
