<p>Okay, I have a couple of questions. </p>
<p>Our school only has Calc AB, so I'm trying to self-study BC, using PR. I'm wondering where the cut off line is between the two - somewhere between integration? Right now, I'm in the middle of integration using PR. Will I be able to take both of the AP tests at the end of the year?.. how exactly does it work? Also, how good is PR -- has anybody else used it? Thanks.</p>
<p>You cannot take both tests, you can only take BC. But when you get the BC score report it includes an AB subscore which is basically your score on just the AB material, and it counts as if you took the AB test seperately.</p>
<p>What's contained on the BC but not the AB: L'hopital's rule, Improper integrals, Partial fractions, Taylor and MacLaurin series, remainder theorem, limits of power functions, integrals of polar and parametric equations (this last one has a lot of subdivisions in it)</p>
