1.9. Course Policies
1.9.1 Exams
All exams are take-home exams. The preliminary exam schedule is provided in the class
syllabus. The tests should be submitted electronically. Credit will not be given for answers
without supporting analyses, or for test turned in late. There must be no collaboration on the
exams. Arrangements for missed exams will be made on an individual basis provided you have
an acceptable, certifiable excuse.
1.9.2 Instructor's policies on incomplete grades and late assignments
Incompletes are accepted only for medical reasons. Makeup work, if any, must be arranged
within two weeks of due date at the option of the instructor, prior to two weeks before the end of
classes. Arrangements for missed tests will be made on an individual basis provided you have an
acceptable, certifiable excuse.
1.9.3 Instructor's policies on attendance for on campus students
Attendance is expected and necessary for success. Attendance will affect your course grade as
part of your class participation grade. I will excuse a small number of absences under certain
special conditions. NCSU policy on attendance, including what constitutes an 'Excused
absence,' is at http://policies.ncsu.edu/regulation/reg-02-20-03.
Work that is late due to an excused absence will either be 'excused' from your grade, or it may be
turned in late. It is the students' responsibility to contact the instructor as well as NC State
Absence Verification as soon as possible to discuss the most appropriate action.
1.9.4 Academic Integrity statement
The faculty acknowledges the existence of the University policy on academic integrity found in
http://studentconduct.ncsu.edu/ and expects students to adhere to it.
An Honor Pledge is expected to be signed and dated on each exam, final exam, and any
additional special assignments. The Honor pledge will be as follows: "I have neither given nor
received unauthorized aid on this test, exam or special assignment. I have not discussed the
contents of this test or exam prior to taking it."
It is the expectation of faculty that students neither give nor receive unauthorized aid on any
exam, or special assignment. The faculty recognizes the value of discussions by students
regarding weekly homework assignments in student groups, with teaching assistants, and the
faculty. However, homework assignments submitted for grading must be the product of the
student submitting the work.
1.9.5 Statement for students with disabilities
Reasonable accommodations will be made for students with verifiable disabilities. In order to
take advantage of available accommodations, students must register with Disability Services for
Students at 1900 Student Health Center, Campus Box 7509, 919-515-7653. For more
information on NC State's policy on working with students with disabilities, please see the

1.9.6 Class evaluation
Online class evaluations will be available for students to complete during the last week of class.
Students will receive an email message directing them to a website where they can login using
their Unity ID and complete evaluations. All evaluations are confidential; instructors will never
know how any particular student responded to any question, and students will never know the
ratings for any particular instructor.
More information about ClassEval is available at https://oirp.ncsu.edu/surveys/classeval
