Course Grades: Your course grades will be calculated via the standard 90%, 80%, 70% scheme. You may check your grades and the class average on the grades website throughout the semester.

Weekly Homework: 20%
Labs: 20%
Midterm Exams: 30%
Final Exam: 30%

Homework: The weekly homework assignments will be posted on the course schedule. Your homework must be written up neatly, on one side of the paper, and stapled. Take pride in your homework by writing legibly, labeling the problems clearly. Homework assignments will be due on Wednesday of each week.

Late Homework policy: You may turn in ONE homework assignment late (within one week of when it was due) with no penalty. All late homework assignments should be clearly labeled with the phrase "Late Math 256 HW" at the top of the first page. Any late assignment turned in without this phrase might be lost, or confused with garbage and accidentally thrown out. Any additional late homework assignment that is turned in will be accepted and corrected at my discretion.

Labs: Throughout the semester approximately 4-6 labs will be assigned. More information regarding the labs will be given in class.

Midterm Exams, and Final Exam: There will be two midterm exams and a final exam. These exams will be taken individually to test your concept understanding, mathematical literacy, and proof writing abilities over the topics covered thus far in the course. The final will be comprehensive. The dates and times of midterm and final exams will posted on the course schedule.

Special Note: If you have a documented disability and anticipate needing accommodations in this course, please make arrangements to meet with me within the first two weeks of the semester. Please request that a Disability Services staff send me the appropriate forms verifying your disability and specifying the accommodation you will need.

Academic Honesty: In accordance with Willamette University CLA catalog: ``Plagiarism and cheating are offenses against the integrity of the courses in which they occur and against the College community as a whole... Ignorance of what constitutes plagiarism shall not be considered a valid defense." For further information about the Willamette University academic honesty policy please refer to the CLA catalog.

On homework: It is appropriate and very helpful to have study groups for homework. Sharing ideas and approaches is a good way to learn. However, students must find their own phrasing and wording for the written homework. Plagiarism is not expected and will not be tolerated. Copied homework will earn a grade of zero for all parties involved.
