Why is it that you’re taking only four classes senior year when you took five your junior year? Aside from that, I would only recommend taking another AP if it’s something that you’ll get credit for, depending on the college you attend. I’m sure an English course and three other AP’s are enough for the counselor to check the “most rigorous courseload” on your college application, considering you took five the year before that. It all depends on what else is offered at your school.
You have a significant amount of APs- I wouldn’t worry about it. The CC class kind of makes up for it, and your admissions decision won’t hinge on one AP.
Calculus C is the second level in the physics sequence and it’s considered the most difficult science class. So if a student likes physics it makes sense to take that class, as long as s/he has taken biology and chemistry in the 9th and 10th grade.
However you should have a fifth class, not an AP (rigor is there) but anything you’ve always wanted to take for fun, be it shop, choir, current events or culinary arts.
