**Class Policy:**

All students are expected to bring their text, calculator, paper and pencil to each scheduled class where academic honesty is the required mode of behavior. Assignments contained herein, and as augmented at instructor's discretion, shall be completed prior to the next scheduled Monday class session and will not be accepted beyond that date without prior instructor approval. Assignments constitute minimum coverage of the required lessons and the student is encouraged to complete additional exercise problems contained within each assigned chapter to promote mastery of the objectives. Course content may vary from this syllabus to meet the needs of this particular class composition. Students are expected to attend all scheduled classes where active participation in class is an integral element and will be considered in final course grades. Should circumstances arise beyond a student's control which may force a student to miss a class session or portion thereof, all matters relating to the absence should be arranged between the student and the instructor, including making up missed work. Absences are particularly significant in this program due to the amount of material covered in each class. Thus students are encouraged to assist one another with missed classnotes and assignments.
