<p>If you had a B in Honors Pre-calc or an A- in Reg Pre-calc, then you take BC.
Anything lower goes to AB, but they do make exceptions.</p>
<p>AB is a year-long course. And so is BC, it just covers two semesters of college calculus.</p>
<p>About 40 kids in my class (juniors) are in calculus. About 30 are in BC Calculus. And about 20 will take Multivariable.</p>
