<p>My son self studied for Comp Sci AB last year, and used the text book and prep book from <a href="http://www.skylit.com/%5B/url%5D">http://www.skylit.com/</a></p>
<p>The year before, he self studied for Calc BC, and used Apostol (which I dont recommend unless you are very good at math). He used the skylit prep book for Calc BC - just to make sure that Apostol had covered everything he would see on the test.</p>
