Professor Zinke is a very funny person who really wants to make sure that students succeed. He was a bit technologically challenged, but overall made a 3-week summer intensive Organic Chemistry class very doable and enjoyable! He offered an extra credit project due the last day of the course that was worth 10 test points (10%) consisting of creating a parody music video about the class content. After the class, he kept in contact through letters and email! REALLY recommend him for his humor, stories, and knowledge! :)
