Maybe I don’t mind stuttering because I’m always talking, so I never wanna shut up. But my uncle (who also stutter) gave me a tip : it’s to change the word you’re going to say every time you stutter. Like, if you can’t manage to say that word, just say another one. I never tried, because I don’t like thinking before I talk, but maybe it could work for you. But, I think your teachers should be patient and I’d doubt they would want to speed you when you’re answering in class (unless you only have teachers like my bio teacher). I’d really like to help you *ପ꒰⑅•ᴗ•｡꒱໊੭*
