Course Objectives

At the end of this course students will be able to:

Course hours: 6 - 7:40 pm, Tuesdays and Thursdays

This is a four credit course. You should expect to spend at least eight hours per week outside of class on this course.


Two in-class exams will each constitute 20% of your grade. The final will be 50%. Class participatin will be 10%. There will be homework; I will not grade (or collect) it.


There is an attendance requirement at Lehman College. Students with poor attendance and repeated lateness (no matter what the reason) will have their grades reduced. If an emergency prevents you from attending class, it is your responsibility to obtain notes from a classmate and study them for understanding. It is a wise move to get a buddy.


Please be in class on time. I will close the classroom door at 6:00 pm. Do not enter the class if the door is closed. I will let all latecomers in at some point between 6:10 and 6:20. If you arrive after the first batch of late students is admitted, knock on the door and wait to be admitted.
