So I'm taking my STNA test on Friday...

On Friday morning I'm taking my STNA exam in Toledo and I'm totally and completely nervous already. I feel like I've studied decently, but the thing that concerns me the most is taking the practical exam. I have a tendency of getting so nervous that I make stupid mistakes, which definitely has me a bit worried.

For all of those STNA's out there: Is there specific tricks or tips I should remember when taking the practical? And what is the best way to get rid of the nerves?
