<p>Has anyone ever tried Thinkwell for AP Calculus BC? How comprehensive is it? </p>
<p>Also it’s 150 dollars for their calculus course (125 for AP Calc AB and BC individually why the heck would anyone buy the two of them since AP Calc BC only has BC topics) while I’m pretty sure JHU CTY uses the same material but charges about 2000 dollars for 9 months for their AP Calculus BC class… is the original Thinkwell class any good? </p>
<p>I also have the Stewart Calculus book as well as the Barron’s book, but the Barron’s book’s explanations are horrendous and it is only good for the problems within. Also the Stewart Calculus book is awfully long (1000 pages) and does not lend itself to being read cover to cover without an accompanying class.</p>
