I'm in some AP classes and they are so much harder than my regular classes but at least i'm starting to get an idea of what to expect next year when i'm in college. if you want her to start working harder than it is good but it probably wont help her decide on a major.

Personally, taking AP classes is a benefit to everyone. For the student, it looks good for college,and rises your GPA. For the parent, it's saves money because it'll count for a college credit. They are tough classes, but are usually manigable. I don't think that students should go extremely crazy with as many AP classes, they need some time for themselves. But, i suppose it depends on the student.
