Thanks to the great study group members, I was able to complete all of them in 5 weeks. (I think I thought a lot about not only completing them, but also what strategies to use in what situations, and trade-offs.) I think the biggest advantage of Younghan's class is that he constantly reminds me of what a practical perspective is. Also, he explains abstract concepts in a way that makes them easy to understand. I've now purchased not only the basics but also the entire series, so I'm going to take the rest.
