Switching from AP Calc BC to AB?

<p>Hi, everyone! I'm currently a junior at my school, and I'm thinking I bit off more than I could chew when I took this class. Sophomore year I was originally planning to take AB, but my teacher rec'ed me for BC, so I took it, and now I think I am in danger of receiving a D for the first semester. I've talked to my teacher recently on moving to AB--he told me he wouldn't completely recommend it, because he doesn't know my capabilities as a student in BC very well (I don't really have the time to come in for extra help due to other classes/activities, and I was unable to reach a suitable tutor at the beginning of the year). I've heard from people that the pace in AB is slower, and I am seriously contemplating on whether I should transfer down for second semester. I'd like to continue with BC because I'd like to try again second semester to redeem myself, but I also don't want to make myself miserable for a class I simply may not have the time for. Any advice? Thank you guys. (:</p>
