Course Policies
-
Grading: Assignments may be submitted up to 3 days late, with a penalty of 15% for each day.
No credit will be given after 3 days.
-
Academic Integrity: Cheating in exams/assignments, plagiarism in exams/assignments, collusion and falsification of academic records constitute academic dishonesty.
Students are responsible for being familiar with UNT’s Students Academic Integrity Policy: https://policy.unt.edu/policy/06-003.
Cheating/collusion/plagiarism in assignments/exams will result
in zero credit for them, possible “F” grade for the course, and possible disciplinary action.
-
Students with Disabilities: Students in need of academic accommodations for disability can refer
to the Office of Disability Access for initiating the required arrangements based on ADA terms.
Also, such the students are welcome to arrange an appointment with me to discuss their special needs
for academic accommodation (to ensure confidentiality).
