If you make her think too much she will get frustrated, especially if she isn't used to having to do it very much. As she gets better work her for a little longer on schooling stuff, but try to make it interesting for her.
I agree, too. Even a 5 yr old only has a certain attention span for schooling, and drilling beyond that is pretty pointless. Also, some horses just get absolutely bored with repetative arena work.
