<p>Calisun:</p>
<p>There is much written on this subject with plenty of evidence that many colleges do take slacking off seriously. I doubt anyone on CC will be able to tell you exactly what BC’s current criteria and threshold is for tearing up your acceptance.</p>
<p>One particular thread on CC is at: <a href=“http://talk.collegeconfidential.com/ask-dean-topics/903319-when-do-colleges-rescind-acceptances.html[/url]”>http://talk.collegeconfidential.com/ask-dean-topics/903319-when-do-colleges-rescind-acceptances.html</a></p>
<p>Why would you let a Calculus grade drop to a D or Physics drop to a C? The BC admissions office has several thousand high school seniors with an academic profile just like yours (the kind you had when they admitted you) that they’d love to admit if they could. Why give BC any reason this spring to look at you and say “I guess we made a mistake here.”</p>
