Perish
Haha, ok, jokes aside, presentations suck. Practice the presentation outside of class. Write a script if you need to. Try to avoid routine movements, such as pacing, because it makes the speech hard to focus on. Try to stare at places on the wall or at table/desk tops instead of directly at people. Wear something comfortable. Try to sneak a bit of humor in there because that makes it more memorable and easier to listen to- also, it's Shakespeare and drama class, so it should have some humor. As for being nervous, know what you're talking about and imagine that you're having a conversation with a friend instead of telling a speech. Try not to be the first or the last to present because that'll build up some serious anxiety before you get up there. Believe in yourself, both because this project will not matter in the wrong run and because you're dedicated enough to feel nervous, so it's gonna be good. The last tip I have is to tell yourself something along the lines of, "Screw it! Whatever happens, happens," before you get up there.
I do acknowledge that all of this is easier said than done, but I hope at least one of these things helps.
