<p>I agree with mcgoogly. Textbooks seem to leave out some information that is actually very useful. I self-taught myself Calc 1 and 2, but I didn’t take the AP test since I am going to take the AP Calc BC class at my school. That is the best way, but whatever floats your boat. I only have one Calc text which isn’t all that good. I’m sure other people have some, but definitely get Princeton Reviews book and Peterson’s as immortalix said. They are very good books.</p>
