<p>^ As has been explained already, BC and AB aren’t two separate curricula. BC is AB with a little extra; in some areas you go further in BC than you do in AB. So no, there really isn’t a “jump” or major gap between the two.</p>
<p>The jump from pre-calculus to BC is not much different than going from pre-calculus to AB. It’s what the majority of the seniors at my HS do and it’s what I would’ve done if I didn’t have the year to spare to do both.</p>
