Gray is decent this semester because he actually covers material that is relevant. God last semester he covered such meaningless bullsh*t it made me want to throat punch him in his smug face. For the homework assignments, those are fine. For the group project, start praying. You have to teach yourself a ton of complicated stuff regarding Tableau that he never covers. Literally, he doesn't go over Tableau in class. And then he expects us to do an entire damn project in Tableau. It's ridiculous.
