Take Calc BC or Stats?

Next year I will be a senior in high school. Last year, I took 3 AP classes, including AP Calc AB. I had a tough time with the class (mostly because of the teacher) and ended up with a C, then a B but I got a 5 on the AP test. I don't want to keep hitting my GPA like that (which is a 4.33 weighted and a 3.63 unweighted) so I signed up for Stats, which is easily the easiest class at our school. I got my SAT scores back though and I got a 2050, which combined with my AP scores, ridiculous extra-curriculars, volunteer work, etc puts me in contention for some great colleges, like Stanford. That is my biggest goal, but I don't know if I should take BC or Stats. BC is with the same teacher and I already will be taking AP Gov't and AP Lit. I'm looking to get my MBA so I'm going to undergrad for Business Admin. What should I do?
