Can someone tell me how much several typos, a missing reference, some stylistic problems will affect the grade of an MSc dissertation. Just (stupidly) read through mine. There are a lot of mistakes (maybe 15-20) in a 15,000word diss. Literature subject. Otherwise, i think its pretty good. Need a certain mark for my PhD condition though (a distinction). I think itw worth of a distinction, but will the errors hammer my grade down? I've got a sticker on it that says i'm dyslexic, but that they shouldnt change marks due to that.
