question about contests

when I went to Nationals '08 I noticed that everytime it was someones turn they were ready to do their freestyle.
I was wondering how the person would know when it was their turn to go.
Please tell me how this works and if it is the same way in most contests.

Usually there is an order when you sign up. So I think they just go, “Okay, I’m after him, so after his freestyle is over, I’ll go on stage”

can anyone else conferm that?

Yes. That’s how i see it as working… (Grammer)
