    Possibly a stupid question, but one that's really panicking me - if you get the wrong results during an isa involving a titration, is there any way you can re-do it or not? I know we get two isa opportunities, but is it possible to just redo the practical element without using up one of these??

    Help would be really appreciated x

    how wrong? usually the best accepted titre by an exam board is +/- 0.10 or 0.20 from your teacher's value.

    I'm redoing my Isa in May, I hate it when the teachers give you a grade and the final markers is able to deduct marks off your Isa. My teacher gave me a B initially and sent it off. When I got it back I got a D back lol I was absolutely shocked- everyone in the class got their mark deducted apart from this one person.

    Seriously wrong; like 0.4 away from what everyone else seems to have got.
    O:
    i'll take that as a no; lol. that almost seems like there'd be no point doing the paper then, as i'm not going to be able to do well overall.
    Thanks for the replies!
