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.

I wouldn't worry about it too much. I submitted mine a few weeks ago and it had a few typos in it. You probably will lose marks for it. but they wont crucify you for it!!

You should just correct what ever typos you find so that if anyone else wants to read your thesis ( like a prospective employer or PhD supervisor ) then they wont find any mistakes
