Should I take Calculus 3 for my senior year in High School?

I am taking Calculus BC (2) and this is the first time I am having B's in Math. They are low B's such as 80% border line. My overall right now is a 76%. I have taken 4 APs my junior year and I don't want to have as much pressure and work for my senior year, especially when I will be writing letters to colleges and scholarships foundations. Next year I will be taking AP Physics C and taking an Internship for half of my day. I have the choice of either taking AP statistics or Calculus 3. Seniors from this year say that Statistics is a joke, that people can easily get an A. Also Calculus 3 looks much, much better on your transcript. HOWEVER, I can't take another year of struggle that I have taken in Calculus BC. Also Calculus 3 starts at 7:15 am, because it is a zero period. There is also Computer Science, but I don't know much about it. I want to get into Universities such as Berkley or Brown. I don't know what to do... :(
