Taking EMT-B skills final today

Hey y'all, as the title says, we are in our last week of school, and it's finals. We have skills testing today, which is pass or fail, and of course, I'm very nervous. I'm doing my course at a local community college in California. I've been doing well in the class overall. The final is based on 3 skills we've learned during the entire course, so BVM, OPA, NPA, igels, spinal immobilization, etc. Any tips and pointers would be gratefully accepted, trying to not to let my nerves get the best of me today.
