Being a little nervous is good... means you'll be on your toes and do well. Too much nervousness can hinder, so if you think it will freeze you up, take a walk or do some jumping Jack's or something physical.
I'm sure you'll do great. Just showing up puts you ahead of a lot of students these days. I think remote school is tough.
