What are my chances of getting my admission revoked?

<p>So I already have been accepted into UC Davis, I sent in my SIR, paid for housing, and did all of that stuff. But the conditions of my admission said i shouldn't get a grade under a C though I got a D in AP Calculus BC. Is there a strong chance of me getting revoked even though I got A's in the rest of my academic classes (three of which were AP). Also I had a C+ in Calculus last semester so it's not like my grade nosedived and I didn't really have to take this class I did it for elective credit. Plus I took AP Calculus AB last year and got straight A's so it's not like I'm dumb or anything but the new teacher hired this year made it difficult. </p>

<p>PS I get to offer a little explanation about my grade should I mention that the teacher was new and had never taught a class above geometry before teaching this class or does that sound too accusatory because I don't want to play the blame game I was at fault too as well as my class which as a whole was pretty rude to her.</p>

<p>PPS What should I include in my explanation.</p>

<p>Please and thank you for any help you can offer.</p>
