I expect you to work willingly. If I see or hear of this happening, all members of the offending group will receive zeroes for the group assignment.

It will consist of an in-class essay which will ask you to synthesize in some way the reading you have done for the semester.
Exams are cumulative and include both an objective and an essay portion.
Grades I use a standard, 10-point grading scale. I have roughly 75 freshman students this semester. I am known as a hard grader and a demanding teacher, but on their evaluations very few of my students say they learned nothing in class, and fewer say they hated being there. If you need tutoring, please let me know. Writing tutors are available in McCutcheon hall, in the basement.
