<p>I'm going to Columbia this fall and unfortunately, I can feel the senioritis setting in. My grades probably aren't going to be stellar (low 90s maybe?) and no, I won't fail anything.
Anyway, how far do the grades have to drop to have them question my worth as a human being and rescind my admission? Do I need to fail a class?</p>
<p>Thanks a bunch! ;)</p>
