Need more details about Andover classes

<p>I've looked over the boards and haven't found much detail about how classes are taught at Andover. In particular, what classes are taught via Harkness and what classes are not. And who decides - teachers or administration? </p>

<p>Additionally, if not Harkness, as opposed to Exeter, how are math courses delivered? Applied word problems in seminar style minus the Harkness? or ? Does the type of class tend more toward Harkness in the higher grades?</p>

<p>Thanks for your insights!</p>
