**Course Organization:** There will be 2 Midterm Examinations and one
Final Examination.
In addition homework will be assigned on a regular
basis and graded. The percentage distribution for the course will be:
Midterm Exam 1 |
20% |

Midterm Exam 2 |
20% |

Homework |
10% |

Final Exam |
40% |

The remaining 10% of the grade will be assessed on a term project and/or
class participation.
