Prof. Worthing has been one of my favorite professors at Delta! The assignments are straight-forward, there's a week extension for each, and the virtual classes are enjoyable. I have nothing but positive feedback for this professor!

All his assignments minus like 2 are through an online textbook (Mccraw). He's great and responds to emails.
