Course Requirements and Evaluation Procedure
1. Homework(s)/Computer Problems: Homework/computer problems will be assigned ahead of time
so that students would have chance to read the related topic(s). Homework/computer problems
assignments will be due at the beginning of the class of the class on the date specified. Absolutely no
late homework/computer problems will be accepted, if not accompanied with a legitimate excuse. All
work on the homework/computer problems assignments must be individual.
Homework, Computer Problems, and Quizzes effect the 20% of the final course grade.
2. Exam(s)
Note :
: Three examinations will be administered.
Exam 1 effects the 25% of the final course grade,
Exam 2 effects the 25% of the final course grade, and
Final Exam effects the 30% of the final course grade.
Students are responsible for all materials/announcements presented in class whether
they are present or absent.

Course Policies
• Students must have the pre/co requisites for EE 308 as given above.
•
No make-up tests will be given.
•
Students are encouraged to discuss the course, including issues raised by the assignments.
However, the solutions to assignments should be individual original work unless otherwise
specified. You may ask a fellow student a question designed to improve your understanding, not
one designed to get the assignment done. To do otherwise is to cheat yourself out of
understanding, as well as to be dishonorable.
•
Any case of cheating will result in an F grade for the course. Also, the case may be forwarded to
the Department Chair for appropriate disciplinary action.
•
Use of one information sheet, 8.5” x 11”, one side only, will be allowed during Exam 1, and 2.
Two one-sided pages may be used for Final Exam. Information sheets are to be individual effort,
and must be turned in with each test.
