AQA Additional Science Biology - Higher Tier

I thought it was mean of them to give us TWO 6 mark questions - I skipped one hoping to come back to it later but then discovered that there was another one at the end The separate science people apparently had an advantage on this one since they've done about osmosis (something similar to diffusion I believe) so had more to talk about.

My teacher came round with the paper a few hours after the exam and said that the question on magnesium and nitrate ions or whatever was not on the spec? The people doing separate science said that it was, but maybe they were just thinking of their unit 3 spec? I'm not sure about this but if it's true I guess AQA weren't paying attention when they made the paper >_>

I'd give the paper a 7/10 too I reckon. Onto chemistry now!
