He is extremely passionate about the subject and really makes lectures enjoyable.  The \"busy work\" that others are referring to is not bad.  Most of the work is done with your group, so finding a group that pulls there own weight is crucial ",

But Stefan's very passionate and quirky, which always made for a fun and interesting class. Glad I took it.",

This is the t-shirt entrepreneur class. No final exams just 5 pop quizzes when I took it. Overall, pretty average class.",

He uses 10+ different online or social media platforms throughout the course and does not make directions clear. It is very difficult to keep up with all of the random busy work that he gives ",
