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.
