I have a speech tomorrow

I have a speech tomorrow I have a short presentation tomorrow, which reminds me of that one time I had a presentation and got 0 points for fluency... lmao. I tried to talk to the prof and explain that while I understand fluency is an important part of giving speeches, it is something I will never achive, no matter how well I would be prepared. For tomorrows speech, even tho we can use notes, I just memorized the whole text. I think it's pointless, I would rather understand what I'm talking about rather than recall the text from memory, but I find myself stuttering less if I don't have to think about what words to use. Any tips will be welcomed tho!! Or your stories with giving speeches, I need to keep my mind busy, because even tho I know I can't be any better prepared, I still am stressed as hell.
