OFFICE HOURS

My office is located in Appleby Center (AC) 222D. If you need to meet with me, please call ext. 4378 to set up an appointment.

EXAMS

There will be 2 unit exams (each worth 200 points) in this course. I do not give Make-up Exams or "Incompletes."

ATTENDANCE POLICY

If you have more than 2 unexcused absences, your course grade will be lowered by one letter grade. If you have more than 4 unexcused absences, you will be given a failing grade in the course. 3 tardies to class will result in 1 unexcused absence. Special needs must be discussed with me in advance of the absence. If you participate in official University activities (athletics, debate, etc.), you need to provide a schedule of events that will require you to miss class. When you miss class, you are responsible for obtaining all class notes, information, etc. from another class member.

MAKE-UP POLICY

Late Assignments: If it isn’t here when it’s due, it’s late. Homework assignments are due at the beginning of class. Trouble with computers is not a valid reason for turning an assignment in late. A 50% reduction in points is assessed if an assignment is turned in late during class, later that day, or the next day. An additional 10% is assessed for each subsequent day. For example, a Tuesday assignment turned in on Thursday loses 60%.

Missed Exams: If you miss an exam, you will receive a zero on the exam. There are no make-up exams unless arrangements have been made prior to the exam and only as a result of severe illness (documented by the Student Health Center) or other significant reason documented and approved by me in advance.

HOW TO SUCCEED IN THE COURSE

• Read the material prior to the day that it will be covered.
• Don’t fall behind; every day is like a week in a normal semester. You won’t have enough time to catch up.
• Come to class prepared to discuss and/or do board work.
• Don’t hesitate to ask questions; there is no such thing as a stupid question!
• Bring your text, notebook, and calculator every day.
