TEXT: Differential Equations: Graphics Models Data by Lomen and Lovelock, Wiley. Do not bring to class unless asked. Chapters 1 through 9, omitting certain sections.

QUIZZES, TESTS and FINAL EXAMINATION: Quizzes will be given about once a week - the lowest two scores are dropped. There will be no makeup quizzes. There will be 4 in-class tests. Test 1 will be on Friday January 18 and will contain prerequisite material. Test 2 : Friday February 22. Test 3 : Friday March 29. Test 4 : Friday April 26. There will be a two-hour final examination on Wednesday May 8, 8:00 - 10:00. Last class: Wednesday May 1.

HOMEWORK and READINGS: Homework and readings will be assigned but will not be collected or graded. These exercises and readings may come up on later quizzes or tests.

GRADING POLICY:
Quizzes: 10%. Tests 1 - 4: 15%. Final Exam: 30%.
A: 90% B: 80% C: 70% D: 60%

MISSED TESTS and MAKE-UPS: A missed test scores zero, except in the case of a fully documented, legitimate excuse which is acceptable to the instructor. If you know you will miss a test, call 621-6893 before the test and leave a message and a telephone number where you can be reached. Students whose excuses are deemed acceptable will be given make-ups at the instructor's convenience.

POLICY ON GRADES OF W, E, and I: The University policy on these grades is enforced.
a) Until Tuesday February 5, you may drop the course without my approval.
b) Should you wish to drop the course between February 6 and Tuesday March 5, you will be awarded a "W".
c) The grade of "I" (incomplete) is reserved for students who cannot complete a SMALL portion of the course for unavoidable reasons. The final examination is usually regarded as a LARGE portion of the course.

TIME SPENT ON THIS COURSE OUT OF CLASS: A general rule-of-thumb is that you should spend a minimum of two hours per week for each one hour of class time. Thus, you should expect to spend at least six hours a week working on this material out of class.

OFFICE HOURS: MWF 7:30 - 8:00 (in Math 101), MWF 8:50 - 9:15 (in Math 314). Open-door policy, and by appointment. I will also use EMAIL to answer your questions.

REMINDERS: The attendance of lectures is not compulsory, but strongly encouraged. It is your responsibility to be aware of all announcements (both written and oral) made in class. It is also your responsibility to be informed of University policies described in the catalog, and in the "Code of Academic Integrity".
