Grading:

Each of you individually selects the grading scheme that you want.

	Option I	Option II*
HW	15%	15%
Midterm	15%	0%
Project	20%	20%
Computer Lab	10%	10%
Final	40%	55%

*Option II is a "come-back kid" option available only to students who have submitted all the homework assignments and who have taken the midterm examination.

Course Policy:

• Homework assignments will be posted at anytime during the week and will be due by start of class Wednesday of the following week. Late homework will not be accepted for any reason once solution sets are posted. There will be no makeup assignments for missed homework. You may (indeed I encourage you to) discuss homework problems in groups. However, when you sit down to write up the solutions, you should do so separately and individually.
• For the computer lab and project, you will need to form groups of 3. The computer lab reports must be submitted individually even though you may work in groups. The group project report is common, but all members of the group must pull their weight! Each group member must indicate his/her major contribution to the project, and all group members must sign off on the report.
• There will be a fifty-minute midterm exam and a take-home final exam. Makeup exams will follow university policy (i.e., provide a really valid excuse for missing the regular exam as verified by the Office of the Associate Dean for Undergraduate Affairs). During the exams, you may use class notes as well as any other handwritten material that you have personally prepared for the course. Do not use any printed material (texts) or photocopies of texts, my lecture notes, or someone else's notes.
