Easy and interesting course, only watched the lectures without reading the textbook and assigned readings, still managed to get an A- on the first midterm. Fully asynch class and Professor Smith is a good teacher and very accommodating with his one time use "oops token" that grants a 2-day no questions asked on a written assignment.

Stay on top of the lectures and you should be good for the midterms. You'll probably even do better if you do read the textbook and readings.
