Grade Evaluation:

Midterm Exam / 35%
Final Exam / 50%
Assignments / 15%
Total / 100%

Final grades: You are guaranteed a passing grade ( that is, D or better) if your final mark is 50% or higher, and you are guaranteed a grade of A+ if your final mark is 95% or higher.

Exam Dates:

Midterm: The midterm exam will be held on Monday, Oct 24, 2011 in class.

Final Exam: The final exam will be held on Wednesday, December14, 2011 at 2:00 pm. The location will be provided on Bear Tracks.

Deferred Eamination: The Deferred final examination will be written on Saturday,

January 14, 2012 at 9 AM in CAB 528.

Please note that the decision for allowing a deferred exam is made by student’s faculty, not by the instructor. There is NO deferred Midterm Exam. If you have a legitimate excuse (incapacitating illness, severe domestic affliction or other compelling reasons, e.g., sports team obligation) for missing the exam, the weight for the midterm exam will be transferred to the final exam. Students are required to submit requests for excused absences within 48 hours of missing the exam.

Note: The use of calculators and cell phones will NOT be permitted during exams (Regarding calculators, don’t worry, you will not be asked to do any extensive calculations on exams). Do not bring books, formula sheets, or scrap paper to the exams.
