Assignments: 
 Homework will be given weekly and constitutes a very important part of the course. Students are encouraged to use Maple (or other such system) whenever it is applicable.   Late homework will not be accepted.

Midterm Exam:    There will be an in-class test.  The exact date of the exam is  Thursday , November 3rd.
Final Exam:        3 hours at the end of the semester.

Evaluation:    The final mark is the maximum of :
                              20% assignments + 20% midterm test + 60% final exam
                             100% final exam
