The final this term departs in some small ways from those of prior terms. To assist you in focusing your study, the following is the "empty shell" of the final, the skeleton upon which the data for the final will be hung. During the final you will be allowed access only to your computer, a calculator, and your writing instruments. Feel free to pass this along and to share this with others in the course.
