You will be graded on "participation."
Please address comments and questions to the discussion "Online Class" on WebCT for this course.

Good questions and good answers both count in your favor.

Please don't ask the group to give you the answer, and don't give away the answer;

Please do discuss the procedures and implications for understanding and finishing the exercises.

Email me you answers privately on but remember class participation counts at least as much.
