Stay calm, don't speed (You'd be surprised how many people do), and try to be friendly with your inspector. Most of the stuff should be pretty obvious, people just get really stressed about it.
So long as you keep a level head, you should be fine.

Oh, and parallel parking is not as hard as people say it is.
No, it's not. It's harder than normal parking, but quite manageable.
Edit: Oh, and good luck by the way.
