Our HS AP Calc teacher was a great guy, and I think we had all the brainpower in my graduating class in the AP2 class. Of the 16 of us in the class, 15 of us either got a 4 or 5. Good stuff.
I got routed into the liberal arts calculus route, which was different from engineer calc in that engineer calc had us working with and familiarizing ourselves with computer programs that would frequently be used down the line. Two of the three calc professors had completely useless lectures. When it came to matrices, the class required us to grind through a system of equations. Ugh.
