If you're looking for a pretty easy 2 credit class with an interesting topic, then by all means sign up. BUT, there is a substantial amount of reading, and a lot of busywork to keep up with outside of class. The professor is engaging and truly cares about the subject matter, and the grading scheme is very fair (if you complete all the work to his standards you'll receive an A). But the course is often frustrating because you spend all this time discussing infinity and posing questions, and by the end of the semester none of those questions are answered. Honestly I just felt very dissatisfied.
