Grading: The course grade will be based on homework, laboratory reports, a midterm, a design project, and a final examination according to the following formula:
Homework average x 20%
Lab average x 20%
Midterm x 20%
Project x 20%
Final Exam x 20%
Homework will have a due date associated with each assignment. Homework turned in late will loose 20% of its value per day (Saturday & Sunday excepted). Late homework will not be accepted after solutions have been presented and zero credit will be given for the assignment.
