Grades:

one quiz  (50% each) and one term paper (50%)

There will be some problem sets designed to help you learn the material. These problem sets will be graded qualitatively and used to determine borderline grades.

Note:  Any student in this course who has a disability that may prevent him/her from fully demonstrating his/her abilities should contact the instructor personally as soon as possible so the instructor can discuss accommodations necessary to ensure full participation and facilitate the student’s educational opportunity.
