Grading
Attendance: You must come to five time in-class sessions during the semester for two hours. Absences during the sessions will affect your grade.
Homework scores are automatically recorded when you use MyMathLab. You should still write the homework problems
and your work in a notebook for future study.
If you get many problems wrong, you should seek help either from the
software (MyMathLab has examples,
step-by-step explanations, etc.), the textbook, the Math/Accounting Learning
Center, or your instructor. Homework is
due by the dates stated in MyMathLab.
It is the last day of each test available except the last homewok set. No
make-up homework will be allowed!
Exams: Three (3) proctored
90-minute tests and a comprehensive 2-hour final exam must be taken at the
