Hey OP, I did my final year thesis presentation luckily only in front of 3 professors. I stuttered damn nearly every word, the worst I'd ever stuttered in my whole life. It felt awful at the time, and I had hidden my stutter from everyone but I couldn't hide it here. I built up the courage before the presentation to tell my year head that I was worried my stutter would affect my grade, and he said it wouldn't. The professors were actually very understanding of it though and I ended up doing well. Just know that most people are understanding of a stutter and they get that it's not easy for you. btw, your English is incredibly good for a second language!
