UCLA Rescind Policy??

Hey Guys,
I’m new here to College Confidential. I’m a high school senior and have been admitted as a freshman to UCLA next fall, for pre-Business Economics. I’m immensely concerned about my current senior grades and how they will affect the continuation of my offer of admission to UCLA. I am taking AP Biology and AP Statistics, and I have gotten 3 C’s (per quarter) in those classes so far, (2C+'s in AP Bio and 1 C+ in AP Stats). In my overall year grade, I am expecting a B+ in AP Stats and a C+ in AP Bio. I have already contacted UCLA about whether this will affect my chances but they are unable to give me a straight answer. Does anyone have any experience with this situation and can tell me if I will get my admissions rescinded or not?
