Does anyone know DeWeese's cutoffs?

<p>Does anyone know the cutoffs he uses? I know 80% of the class gets As or Bs, but 80% of the class did not get >80% on either midterm.</p>

<p>With the lowest MasteringPhysics dropped and assuming I got 5/5 on the last lab, I have 79.62% in the class. I want to know how I need to do on the final to get an A-.</p>
