<p>At NU, 1 credit = 1 course for virtually all courses. The only exception to this is musical performance (instruments). So credits and courses are the same thing. </p>
<p>Perhaps I am missing and misunderstanding something, Alexandre. Aren’t most classes worth 3 credit-hour with only a small minority being 2 or 4 credit-hour anyway at UMich? So % credit hours taught is not materiality different from % classes taught?</p>
<p>If there were some classes that worth 100 credit hours while others were worth only 1 credit hour, then we’d have had a situation where % credit hours and % classes could be very different. But that doesn’t seem to be the case.</p>
