Decent amount of work but very practical. Poorly organized, difficult material, poorly taught. Brilliant professor who cannot relate to introductory doltish students. Frankly, if Marc teaches it, you should have a little background or do some basic preparatory work to maximize your learning. Lectures constitute the substance of the course.
Readings only supplement the material covered in lecture.
Keep up with the readings. Dr. Roberts is clearly very knowledgeable. His teaching style however is quite distracting and difficult to follow. Good basic economics coverage. Take it only with Dr. Hemenway.
