Will a C get my acceptance revoked?

<p>I've never gotten a C before in my life, and AP Chemistry has beaten me significantly. I have a C-, and I'm worried that colleges may revoke my acceptance. I've gotten into Penn State and U Pitt so far, and my other applications have been received by school weeks ago, but will this one bad grade harm my chances significantly? I'm really stressing out...</p>

<p>Your acceptance will not be revoked for a C, but don’t let it drop any further.</p>
