I'm doing Edexcel music!!
It's so difficult isn't it?! I'm aiming for an A as well, what did you get at AS?
What are you finding especially hard at the moment? One thing I found helpful in learning all the points for the long answer question part of the exam was making mnemonics of all the information for each piece. It did work, I got full marks in one long answer question and 13/18 in the other I think?
