About a year ago, while I was only a few weeks into the first graduate-level course I ever took, I tried asking a bunch of grad students what the difference between taking courses at the graduate level and the undergraduate level is. Being researchers in training (researchers are, in my experience, terrible at explaining themselves), they gave me delightful non-answers such as “it’s not that different” (this is a lie) and “your professors treat you like adults” (whatever that means).
