Discuss mid-term exam.  Scores ranged from the mid-teens to the high 20s (out of 30 possible).

The main issue appeared to be a lack of confidence with going from the z-transform representation to the frequency response magnitude.  You will be getting additional review problems to fix this shortcoming!
