What are my chances?/Advice about an AP situation

APs:
AP Physics 1&2–> B first semester, A second
AP Calculus AB–> Currently have a 97
AP Psychology–> Currently have an 96
AP Physics C–> Currently have a 75
Honors:
U.S history–> A both semesters
World History: A both semesters
Spanish 3–> A both semesters
Chemistry–> A both semesters

I have a 4.162 Weighted GPA, 3.965 unweighted, ACT 29 ( I’m waiting on my results from my retake), My school doesn’t do class rank
I’m from a suburb of Chicago and my school ranks in the top 20 of the state.

I played basketball for one year, Soccer for 3, Volleyball for 4, I’m a representative for student council, and a member of a drug and alcohol free sports club called ACE

I’ve been told my essay is very good, but what I am most concerned with is my current AP physics grade. It’s at a 75 and I think I could move it up to a B, but I might not be able to. Will it look bad for me to get a C or should I stick it out.
Any advice would be greatly appreciated!

One C your senior year will not hurt you with the rest of your stats. Follow the advice of your parents and guidance counselor.
