You'll do well! I have a school presentation on Saturday, so I know how it feels. The nervousness. Yours is for a bigger audience than mine, though...

Oh and a tip: if you feel nervous the day of the presentation, just imagine yourself running through the whole thing and totally getting everything exactly as you want and right. Kind of a visuallization. Also you can video record yourself doing it on your cell phone if you have a smartphone and that will kind of simulate the online environment if you want to give a mock presentation that way. Just two ways to maybe prepare if you're feeling nervous.
