No, it doesn't . As a matter of fact I was looking at the Religious Studies AEA last night. Go to EDEXCEL's website and check it out. It also has a marking criteria or something and things candidates ought to mention in their answers .
I did AEA Geography and didn't have to do any extra work. It was very current affairs based and there was alot more emphasis on the human element of geography. The main focus of the paper I did was on evironmental concerns and the Kyoto Agreement.
I got a merit. I was really happy with that considering that 1) I didn't have to do any additional work, and, 2) On the Sunday before the exam on the Tuesday I ended up in hospital with a really nasty virus and had to go on a drip etc.
