<p>Aight, I'm currently in AP Calc AB (I didn't get into BC last spring). I'd just like to take the BC test for the sake of doing the most I possibly can. AB is a breeze for me, maybe even more so. BC can't be that big of a leap. So how hard is it to take the AB course and take the BC test?</p>
<p>Many students do this, in particular, students at schools that do not offer BC. BC is not that much extra in terms of concepts. You just learn integration techniques, L'Hopital, improper integrals, and series. In fact, you could probably learn it all from a prep book in a week or two.</p>
<p>is there anything more to L'Hopital than knowing what it is?</p>
<p>I don't see any other applications in my book for L'Hopital's Rule other than indeterminant limits, but I can't say for sure that there's nothing else to know. I would think AB teachers would want to teach that to their students regardless of whether it's AB or BC, because it can make finding some limits (for multiple choice problems) a lot easier.</p>
<p>And do you have any idea when you'll be finishing the AB course? We're taking our time, because apparently we have a lot of it, and we'll still finish in March, so you should have plenty of time to self-study the additional "C" part of Calculus if you have a desire to do so.</p>
<p>If you feel that AB is a breeze for you, then you can definitely do BC by yourself.</p>
<p>Download the sample syllabus from collegeboard and make sure you know the additional topics.</p>
<p>Have fun :)</p>
