Attendance is expected during all weeks of the semester (including the Add/Drop period). Poor attendance may dramatically impact grades; therefore, students who miss a substantial number of classes may want to consider withdrawing from the course (deadline is the 10th week of the semester; see the Grading System section for more information). Also, depending on the circumstance, a student who has repeated absences should consider speaking with his/her Department Chair and Academic Advisor about taking Academic Leave (See the Academic Leave section).
