    I have the physics unit 3 in less than two weeks and our teacher didn't even finish the course, we've had to read about and learn transformers and stuff all on our own :|

    so scared, I got a B for my biology unit 1, does that mean I can't get an A* overall even if I get an A* in B" and B3?

    You can still get an A* overall - you need a total of 360/400 UMS for an A*.
    If you got 70 UMS in B1 then you need a further 290 out of the remaining 300 available UMS marks between B2, B3 and your ISA for an A* overall. So if you don't lose more than 10 UMS in total between B2, B3 and whatever you got in your ISA (e.g. 90, 100, 100 or 95, 95, 100 or 97, 95, 98 etc.) then you can get an A* overall.

    I find B3 pretty simple but i always forget the production of stuff using microorganisms i.e. beer, yoghurt, biogas

    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?!

    Because the question wanted you to use the diagram for your answer, you cannot tell from the diagram that the alveoli are moist.
