In the Fall of 2015 I was a Teaching Assistant for the Senior Problem class at the University of Memphis. The class is designed to be a final test for graduating seniors where they conceptualize a fictional business and then create an entire identity for it. It's an extremely intense and focused course but the students usually pull through with flying colors.
My responsibilities were essentially to help out the students with any technical or theoretical help they needed. I would spend about fifteen minutes with each student every class period helping them shape their projects.
