Finding it alright.. Didn't think the Jan 2012 one was too bad?
Have a question though.. In the AQA biology textbook in the section about the alveoli, it lists the different factors which are beneficial for diffusion and having a moist surface which aids with diffusing the oxygen.
I did a practise paper, after learning it all, and when a question came up about the alveoli, one of the points I put was that it has a moist surface. In the mark scheme, though, it specifically said 'reject moist surface.'
Why are AQA putting things in their textbooks if they then reject it in the exam?!
