<p>I took Calculus BC my sophomore year. It was one of the toughest courses because I didn’t have the Calc AB knowledge. Sure, the teacher went over it again, but it’s at a much faster pace. Calculus is really different than precalc and algebra, so I recommend taking Calc AB first. The teacher truly does matter, and if the valedictorian got a C in that class, then it seems like it would be super hard. I’m pretty sure taking Calc AB or BC won’t be the deciding factor if you get accepted to an ivy league or not. You’re schedule is rigorous enough.</p>
