<p>Has anyone taken AP Calculus (preferably AB) online through John Hopkins Center for the Talented Youth? I was just wondering a few things: how much time did you put into it (how many hours per day/week), how challenging was it, and just any advice that you would have.</p>
<p>IMO, online courses for calc are a bit worthless, because you can just self study and use opencourseware if you have questions.</p>
