Will my admission to CMU be rescinded?

<p>So, I was admitted to CMU for vocal performances (College of Fine Arts) with about a 3.8 (weighted) GPA. For vocal performance, about 80% of your admittance is based on your audition and the review of your actual grades and stats and extracurriculars count for the remaining 20% (admissions people were very up front about that and used those exact numbers... and besides, how else would I have gotten into Carnegie Mellon with a 3.8 and 2010 SAT scores?)
The problem is the I just got my 3rd quarter grades back and my GPA has dropped down to a 3.27 with 2 As, 1 A-, a C+, a C-, and a D+. Pretty scary.
I'd say that the school wants me, I'm upper-middle class and they gave me $2,000 for the Carnegie Scholarship and when we showed them that I was getting more from other schools they topped all of them and gave me a total of $12,500 in scholarship money. I'm still really worried about my grades though, as I know CMU is a top notch school and doesn't mess around. Does anyone think my admission will be rescinded? Should I be up front about it and call the admissions office or should I try to slide by under the radar? I'm not required to send second semester grades, does admissions go around calling everyone's school? I'm very confused.</p>

<p>For the love of god… I’ve said it 100 times and I’ll say it again: CMU ad-com has explicitly stated that you are allowed to fail one class, and past that you get a warning/rescinding. YOU ARE FINE. Enjoy the rest of your year.</p>
