Final Exam (Dec. 9, Monday, 1:00 – 3:00pm) **2-hour Final Exam**

Policies:

• There will be two quizzes, two intermediate exams, one design problem and a final exam.

• Homework assignments will be assigned regularly, but graded mainly based on the
completeness of the attempt rather than the correctness of the answer. Numerical grades
will not be given for the homework. The solutions will be provided.
• For DE sections, all assignments should be sent to
Homework_EOL@ncsu.edu

The hard copies will be made by the EOL personnel and sent to me via campus mail.
• More will come on Design Problem. Students are strongly encouraged to get into a group
of two or three people as soon as the semester begins to discuss homework problems together
and to do the design problem in teams.

• The final grade will be given according to the following weights:

Homework 10 %
Two Tests 40 %
Quizzes 10%
Design Problem 10 %
Final Exam 30 %

• Class attendance is STRONGLY recommended.

It is the responsibility of each student to be familiar with the NCSU Code of Student Conduct,
and in particular with those portions pertaining to academic dishonesty. The essential idea is
that “The act of submitting work for evaluation or to meet a requirement is regarded as
assurance that the work is the result of the student’s own thought and study, produced without
assistance, and stated in that student’s own words ...” Any questions regarding acceptable
behavior should be referred to the instructor before proceeding.
