[quote=@Legend] Here, Calc AB and BC are both in Calc 1, but we almost entirely combine them. In IB, we go from Calc AB to IB Math, while AP students go to BC, but they're similar enough that our teacher allows IB students to get a Calc BC handout and then take the test. Almost all of her students get fives. [/quote] Ah. Well, we're doing series.
