An interesting class for an econ elective. Professor Lu gave fairly engaging lectures, and his midterms/finals were very similar to the practice tests he gives. He isn't really helpful when it comes to specific questions though, and never answered questions on the campuswire in any sort of detail, if at all. 2 problem sets, 1 midterm, 1 final. Pretty light work for an econ class as long as you keep up with the material.
