Just starting, need help!!

Hello everyone,
I'm just starting at my local Michael's as a teacher. I just received my master teacher and all my materials yesterday to begin training to be certified. My first class is this Friday and I'm a little nervous... I know technique and how to show someone how to do crochet but I'm finding myself widely not prepared (probably more mentally than anything else) for my very first class. Can someone give me some pointers to help kind of alleviate some of my jitters? Thanks!
