I started college after stuttering all through elementary, middle school, and high school. I was incredibly internalized at that point so I was dreading my speech class the entire summer beforehand. Turns out everyone else in the class (25-30 people?) was really nice, the teacher was awesome, and it was probably one of my favorite classes of my entire college career. Some speeches we got to use notes, other ones we weren't allowed to - I noticed those without notes were much easier for me. Nobody ever made us read anything we had pre-written ahead of time, which I liked. I don't know about anyone else, but it always made me feel better to volunteer to go first. I think everyone has lower expectations, they'll think it's just nerves, and you trick yourself into feeling more confident than you probably are. Good luck - hope you enjoy your class as much as I did!
