Edexcel have password protected their past papers... I haven't been able to find any on google. All I could find was model answers (which I can't really judge the difficulty from).
The 2006 in retrospect were "weird" to compensate for the lack of weirdness that was not present in previous years. The hard questions seemed so easy that at one point I made sure that it was the Higher Tier and that if I was letting myself get tricked by the question.
Indeed, they had a certain slant this year which made them different. Could have been better, but they also could have been much, much worse.
I only got 63.5% for that 2004 Edexcel Maths papers in my mocks in January year 10. That cannot have been an A though.
I did French in yr8 (A*), Spanish in yr9 (A), Double Science in yr9 (A*, but now that AQA is withdrawing it everyone in the year below us gets to do Biology, Chemistry, Physics), and English Language in yr10 (pending - not Literature I'm afraid).
ihavent yet but i am hoping to do maths or ict GCSEs during the summer, im year9 when i get back to school after holiday
