Course Policies
Make-up exams
If a student misses class for a valid reason, it is the responsibility of the student to obtain the information and material covered in the missed session. The student will be given the opportunity to take a makeup for the missed quiz the week after.
Extra Credit
N/A
Late Work
Late work will not be accepted unless a valid reason for the late submission is presented.
Special Assignments
Class Attendance
Students are expected to attend all class sessions and off-campus meetings that may be arranged with visiting scholars. Attendance and participation is vital to successful completion of the course. (Refer to The North Carolina Agricultural and Technical State University Bulletin on Class Attendance Policy, page 77). In case of excused absences, students have the responsibility to obtain the information and material covered on the session. Excuses will be granted according to NC.A&T SU student handbook.
Moreover, the College of Arts and Sciences requires students to be on time for class and to attend class on a regular basis. If the student has unexcused absences, is late for class or leaves class early, the student’s grade may be lowered.
(See attendance policy set forth by the instructor in the course syllabus.)
Excused absences will comply with the following university policy on make-up work: “Sickness (verification needed); death of relative (immediate family); participation in an approved university related activity; acting in the capacity of a university representative (band, choir, sports, related travel, etc.); extraordinary circumstances including court appearances, family emergency~ at the discretion of the professor, etc. require a signed statement.
NOTE: “Other reasons for class absences are not acceptable.”
Classroom Citizenship
Enrollment in the class means that you agree to abide by the expectations of North Carolina A&T State University about academic integrity. For specific information refer to your Student Handbook. Also, refer to the most current Undergraduate Bulletin for the academic dishonesty policy. The North Carolina A&T State University’s Academic Honor Code will be enforced.
Your responsibilities in the area of honor include, but are not limited to, avoidance of cheating, plagiarism and improper or illegal use of technology. Your presentations, assignments, and quizzes are expected to be your own work. Any questions about these should be directed to the professor. It is permissible to request assistance from a librarian when doing database research as long as the selection and organization of the research for the presentation is in your own work.
Technical Support
If you experience any problems with your A&T account you may call Aggie Tech Support (formerly Help Desk) at 336.334.7195.
