Possible admission revoked?

<p>So in Feb. I was accepted into UCF, which from what I'm told, really isn't that hard to get in to. My fall semester, I had about a 4.3 gpa, was taking one DE class and one AP class. My spring semester, I was taking two DE classes and two AP classes. Now, I know I got a high B in one of my DE classes one and a low B in one of the AP classes, and I got a 72 in my other AP class. I'm very concerned about my calc. class though. It's DE and I might have ended up with a high D, though I haven't gone by the school to get the final grade.</p>

<p>I'm aware that getting an admittance rescinded is rare, and not something colleges like to do unless a students grades drop significantly, and that usually a stray C isn't something to go crazy over. And in my defense, my math grades have never been all that great, I've averaged C's all throughout high school. </p>

<p>Anyway, I'm contacting the admittance office tomorrow, just to see where I stand (I graduated about 3 weeks ago and final grades should have been sent by now), but in the mean time, can anyone tell me what my chances are of being rescinded just because of that one grade?</p>
