Sounds like she needs a new 22. What brand of 22 was she shooting?
Sounds like you know what you need to work on to improve. Remember to work on one thing at a time (with grip, don't worry about where you're shooting, just work on your grip) when you have that down move on to another thing. Shooting the same gun every time will help you improve your shooting.

Having fun is what it's all about.
