Calculus in high school over two years -- why?

<p>My D is a junior who is currently taking precalculus. Her HS has an amazing AP Stats teacher and mediocre AP Calc AB teachers, so she is choosing to take AP Stats senior year and Calculus at the local community college over the summer. I’m assuming (based on articulation agreements and the like) that the community college calc course is going to be similar to those taught at most other colleges. D is not aiming for top colleges or for a STEM major, so I think she should be OK with this approach. Any thoughts?</p>
