HOMEWORK AND EXAMS:

There will be ten (10) graded homework assignments. Depending on the class performance on the homework, there may also be one (1) midterm and one (1) final exam. These exams will be take-home, open book.

GRADING:

Your grade will be determined by equally weighting your performance on each of the three course requirements: homework, midterm and final. Extra consideration will also be given for classroom participation/facility with the lecture material demonstrated during dialogue with the instructor.

EVALUATION EXAM:

It has unfortunately been the case in past years that some students registering for this course lack the requisite mathematical maturity. For this reason during the first class meeting an �evaluation exam� to test students� competency in elementary calculus, analysis, linear algebra, linear programming and numerical methods will be assigned as the first homework. It is due at the beginning of the second lecture and will be graded. A threshold score will be stipulated by the instructor. Students scoring below this threshold are strongly urged NOT to take this course for credit since it is unlikely that they will receive a grade of B or higher.
