nicoledad, I wonder if the course combo called Trig/CalcA is the equivalent of what our district calls "Pre-Calculus" - it follows Algebra II and is a pre-requisite for Calculus, and here includes Trigonometry. It's not an AP course thought - the only AP courses listed on the College Board site for Calc are "Calculus AB" and "Calculus BC". It also makes sense to limit Calc AB to seniors because if you take it as a junior, what math course makes sense to follow it? The first semester of Calc BC would be a total repeat of Calc AB, and there isn't an AP course covering second semester calculus only - so you'd either have to enroll in a local college or take it online. Plus most kids (I"m guessing all students really) who are advanced enough in ability to be plugged into pre-calc by the time they are sophomores really ought to be able to handle Calculus BC, and quite a few if not most of them might be bored with the pace of Calc AB.
