    I got half way through this paper and realised I had little time left (around the photosynthesis part:s) so rushed through the rest... I'm really worried; a lot of my reaction stuff seems wrong and I didn't answer the photosynth question or the last one (nine marks worth of stuff)

    Kpop dude! I found this one harder than Jan but I only did Jan as a mock :s
    Haha well I'm guessing it was cause all my weaknesses came in Jan -.- (Like enthalpy of neutralisation + there was no buffers!) But apparently this exam was really hard since everyone's yelling at me for that comment LMAO
