AP Calc for an upcoming senior

<p>Hi. So as I'm finishing up my junior year I am deciding whether or not I should go to AP Calc BC or AB. I was in Honors precalc BC this year and have a solid 90. Personally, I am not really happy with this grade but more than that I just don't understand the material and rarely know what the questions are asking. I fear that I will struggle in Ap Calc BC and might end up in the 80s... or maybe worse. Will dropping into AB be a better option, especially because I have already learned more than half the Ap calc AB curriculum in Precalc BC?<br>
Basically, my question is what looks worse: Getting a B,B- in AP calc BC or dropping down into AB? I'm not looking to go into science or math, I just look to take all of the most challenging courses if that makes any difference. Also, I will be applying to some top schools, possibly even Ivys.<br>
Thank you in advance.</p>
