Hi! I don't know if you've already given your presentation, but I wanted to add in a few suggestions as I am also a student with a severe stutter! I gave a presentation in my English class a few weeks ago and I got an A on it, the entire time I was struggling to say even a few words in each sentence. But the first thing that I will always recommend to people who stutter or are nervous is to outright say that you have a stutter and you are very nervous right now. I did it and it helped give me relief during my presentation! Another thing I would totally recommend is to maintain and give eye contact with everyone in the crowd. Let them see that even though you are scared, YOU are in control of this situation. Do not look at the ground, your feet, or hands; Maintain eye contact the entire time. Don't envision anyone laughing at you. There will be odd states, some bored faces, maybe even a little snicker here or there depending on the maturity level in the room at that moment. BUT IT DOESN'T MATTER UNLESS YOU GIVE IT MEANING. Just focus on articulating yourself in the best way possible so you can get that A! The last piece of advice would be to try your best and don't beat yourself up over it at all, you're going to do great!
