Demerits and Classroom Etiquette:

  • Your instructor reserves the right to make modifications in content and schedules as necessary to promote the best possible educational experience.
  • Cell phones are prohibited in class.  If a student’s cell phone goes off in class the student will be required to silence or turn the phone off unanswered. If there is an emergency, the student should notify the instructor ASAP.
  • Demerits may be given for unprofessional classroom conduct and includes, but is not limited to, the list in Student Handbook.
Absences

Students are strongly encouraged to attend all lecture and laboratory classes. It is the student’s responsibility to discuss any missed material with the instructor and schedule any necessary make-up time for lab assignments. Students who arrive between 1 (one) and 15 (fifteen) minutes after the start of class will receive a “T” tardy for that class period. An accumulation of 4 (four) tardies will constitute 1 (one) absence. Students who arrive more than 15 (fifteen) minutes late will be counted absent for that class. A maximum of four (4) absences are allowed per class. Any additional absences will result in a 10% reduction in the final grade for each additional absence.
