Just a FYI. Something to check is where your child would take the AP exam. While officially college board doesn't require you take the class, not all testing locations (ie High Schools) will let you sign up if you aren't enrolled at the school or enrolled in their class. It's not like the SAT's where you sign up on the College board web site, you sign up through the H.S. where the tests are given. I know of a recent student who self studied for an AP exam who was having difficulty finding a testing location.
