I had to take it as a pre-requisite. Definitely wouldn't have taken it on my own free will. I approached it with a positive attitude though. As some people have mentioned, it's much easier to inform the audience and professor that you stutter. Also if it's easier, do some research on the professor and class beforehand. For example, in my class, we gave speeches weekly in front of small groups (about 3-5 people) whereas in another friend's class, they had to speak in front of the whole class on a regular basis. Good luck! Some people said they were re-taking the class for the n-th time because they were too afraid to continue in the past, and they don't even stutter!
