    You need a fair bit of depth, I'm afraid. Try to learn the all the reactions you've been taught and the sequence in which they occur - and very importantly, where in the mitochondrion/cell they take place. I seem to remember this came up in several of the past papers I did before the exam. Can't tell you whether it was actually on the exam cos I blanked it all out, sorry!

    Good luck with your exam!

    imdoing aqa too- and for that topic it just seems we get taught way more than we need. get hold of some past papers and see what level the questions are at. Also, the syllabus is so helpful, the proper aqa one, from the net. For krebs cycle you definitely need to know the length's of carbon chains and how they change, what changes them, and all the substances taken in and given off and where in the cycle they occur. Just draw a massive circle and annotate it, there isnt that much at all.
    If you want to know anything else PM me.
