    OCR 21st century science C4 C5 C6
    Is anyone doing this exam? It's my last one! YAY!! I was just wondering if anyone knew what was going to be on it, had any notes or knew where I could get a past paper with answers from before 2007.

    my last one also! tbh, I think it was pretty pointless having science lessons. They should just give us that pink 'GCSE additional Science Revision' book (the official 21st century revision guide) and tell us to memorise it. That's all that comes up on the papers anyway.

    I haven't been revising. More like 'learning' (my school is pretty crap). done c4 and c5 and now on to c6!

    Exactly this.
    My science teacher is absolutely useless and had only taught us c4 he said we are a noisy class so we need to learn the rest ourselves :rant:
    I'm so annoyed because i'm desperately trying to learn everything.
    I just hope i do well tbh

    Any answers?

    I think I got some of it wrong, which annoys me.

    For the ions I put K2 2+ and SO4 2-. I put it wasn't a precipate, but not sure what that is entirely. Yeah, pretty much all I'm unsure about...
