Yeah, his lectures can be a little dense but honestly Walt is such a great professor. Seriously one of, if not the best professors I've ever had, and this is my senior year at Miami. It helps that I was genuinely interested in the subject he was teaching but Walt was hilarious, passionate, and very helpful, and the class is not super difficult. I 100% recommend him!!! His lectures really make sense and are easy to follow, he really makes you think outside of the box. Tests are 4 short essays and he grades lightly, just show you understand concepts. A little participation goes a long way with him. Great guy.
