I guess I'm in a separate boat to everyone else here when I say it's fine if you don't have to do presentations in the class. The main thing about me and my stutter getting better or worse was confidence. A successful period of speech would improve my confidence and reduce my stutter and similarly the other way around. I knew for a fact when I was in school that if I had to do the presentations I would stutter and it would dent my confidence and I wouldn't handle the laughter and people taking the mick. My confidence grew from talking to other people and I think school is a pretty horrible place to be with your stutter.
