Screwed up my junior year

Throughout all my high school classes I have had mainly A s and some Bs. However, Junior year I recieved 2 Cs, one in AP Computer Science and the other in Physics. The problem is that I am trying to do a Computer Science major. It’s not that i’m terrible at CS either, I took AP Comp Science Principles the same year and ended the year with a very strong A. I’m trying to know what I can do to boost my appliication in regard to my major.

A’s in Calculus.
