I hope everything goes well for you. I would suggest having a conversation with your professor before hand. If i could go back 20 years to when I was in college i would have told a lot more people beforehand because professors trying to finish my sentence or bail me out of something they think is incompetence was just a constant path of frustration and anger for me. I started being open about my stutter and being an advocate for all that suffer from the affliction when I was in my early 30s and I wish I had done it sooner. Good luck and cheers!
