Tell her to sit this one out if she can't do any tricks. I'd find it a waste of time to be honest when you could be working to get her better. Instead, go to the competition yourself and watch the athletes in her age group. When she can confidently do what the girls that get a podium spot are doing, then let her compete. I never got the whole "just enter for the hell of it" thing. Especially with next to no experience even riding in a pipe.
