I am taking my driving test tomorrow for the North Carolina DMV what should I expect?

I've heard a lot but im nervous and don't know what to do with an examiner? What do I do when I first get in the car? what if I fail? When can I go back and try again? thank you for all your help.|||Make sure you know all the rules in driving. e.g. buckling up, proper use of rear and side view mirrors. Read the driver's license manual.
