Put your stutter aside for a moment. Focus on presentations methods and techniques. Practice your presentations. Know them forwards and backwards. So much so, that you can do it without reading it. That way, you can just have a bullet point cheat sheet. Be so practiced that the cheat sheet is just a reference for if you blank. You aren't going to be reading it. When I forget a minor point, and have already moved on, so be it. Leave it in the rear view mirror. Classroom? Board room? Don't glue yourself to the podium. Move around as you present. Own the space. The whole room belongs to you. If you can get access to the room a day or so before hand, practice in that room. Speak to the empty room. Is this for a class? If so, ask your teacher if you can present first. Anxiety sitting and waiting for the person in front of you to finish is brutal. It's October. Lean into the holiday. Leave some tootsie rolls or other small Halloween candy on the tables for your audience. Are you using visual aids? Be creative. I once had a communications class where I had to teach the class something. Anything I wanted. I taught them how to deal Texas Hold Em. Before class, I sprayed 3M 77 repositionable glue on the board. So when I placed playing cards on the board, they 'magically' stuck to the board. Visual aids can focus their attention on material, taking eyes off of you.
