<p>In 2011, I was a regular admitted student and went through something similar. I really messed up and received a C- in Calc, the equivalent of a failing grade. During the 2nd semester (might be diff since you’re on quarter system), my admissions officer told me that I had to submit a reason for the failing grade where the admissions committee would review my admissions decision and my final grade in the class. I eventually ended up with a B, submitted my reason, all of my other grades were good, and my admissions officer notified me that my admissions offer still was on the table.</p>
<p>Before all of this I met my admissions officer at a college fair and he did not seem too worried for me. <em>In my opinion</em>, I don’t think AU Admissions would rescind over one bad grade, especially one that’s still passing. </p>
<p>But this is a new admissions cycle and you’re ED1 so you never know. Why not just directly ask your admissions officer?</p>
