Hi, I'm also a student and do presentations once in a while. Here's my tip for you, I hope it'll work. During our face-to-face classes, I was assigned to do a presentation by myself. I was so nervous and even cried the night before it. What I did is, I play a really loud music in my earphones during my presentation. It eased my anxiety a lot because I don't get to hear my voice, and the less I hear my voice, the less I stutter. :) And also, if you don't get to hear your stuttering voice during it, you would think less about it. Having a stutter when you're a student is really hard and nerve-wrecking. And it's okay to feel nervous, we humans feel nervous at some point of lives and that's humane. I wish you a good luck and I hope you wouldn't beat yourself up if you stutter during your presentation. :))
