HONOR CODE and ACADEMIC MISCONDUCT: "Being a student of a higher standard, I pledge to embody
the principles of academic integrity." Any form of plagiarism is considered academic misconduct and will carry a
minimum penalty of an "F" for the assignment in question. The instructor reserves the right to enforce a more
stringent penalty. Please refer to http://www.latech.edu/tech/students/honor-code.pdf.
EXAMINATIONS: Three 100-point tests and a 150-point comprehensive final exam. In the event of a question
regarding an exam grade or final grade, it will be the responsibility of the student to retain and present graded

classroom accommodations based on a disability must discuss the need with me as soon as possible.
EMERGENCY NOTIFICATION SYSTEM: All Louisiana Tech students are strongly encouraged to enroll and
update their contact information in the Emergency Notification System. It takes just a few seconds to ensure you're
able to receive important text and voice alerts in the event of a campus emergency. For more information on the
Emergency Notification System, please visit http://www.latech.edu/administration/ens.html
EMERGENCY OR DISASTER INFORMATION: There will be sufficient information stored on blackboard so
that the course can be continued in case of an emergency or a disaster. If this does happen, there will be an
announcement on BlackBoard informing you about what you should do.
