Homework

Homework will be collected each Tuesday at the start of class. Late homework (after 4pm on due date) will not be accepted. Attendance in lectures, in addition to working diligently and consistently on the homework is essential for your success in this course.

Make-up Policy

There will be no make-up exams except for excused absences due to extreme circumstances (at the discretion of the instructor). The instructor has to be informed IN ADVANCE by email, and you will be required to provide supporting documentation.

Incomplete Policy

Incompletes for the semester grade will only be granted for work missed due to excused absences. This includes illness during the final.
Please be mindful of the drop dates for the course, and consult with your academic advisor if you have any academic difficulties.
An incomplete will not be granted if the completed work is not at a passing level. In no case will an incomplete be granted for work already completed at an unsatisfactory level.

Grading

The course grade will be based on the following:
Homework: 10%
Computer Laboratory: 20%
2 Midterms (in-class): 20% each
Final: 30%
Books, notes, and calculators are prohibited during exams.

Examinations

The first midterm exam will be on Thursday, February 28, 2008, in class, from 10:30am to 11:45am, and will cover all the material up to and including Section 3.7 (Variation of Parameters). There will be approximately 5 open response questions (possibly with multiple parts), and it will be closed book, closed notes, and no calculators will be allowed.
The second midterm exam will be on Thursday, April 10, 2008, in class, from 10:30am to 11:45am, and will cover all the material up to and including Section 5.4. In particular, it will emphasize the material on higher-order linear equations, and power series solutions of diffferential equations.
The final exam will be on Wednesday, April 30, 7pm to 9pm.
