Duke first quarter grade report (urgent!!!)

<p>Now I have submitted my ED to Duke(Pratt). I learned that I had to complete my app by submitting my quarter grade. I have all straight As except for one course, an university math course, in which I have a C. That math course is comprised of the brightest minds of my school, and half of the class is literally failing because of how harsh my math teacher is.
I'm taking 5 APs or university courses this year.</p>

<p>How would that C hurt my chance?</p>

<p>There is a way out: I could boost my first quarter grades by taking the retakes. That will happen after my first quarter ends but before November 12th, the day Duke requires first quarter grade. Should I hold on to my first quarter grade report until, see, November 10th?</p>

<p>Thank you for your time.</p>
