Online Course Access

Access to the course lecture portal is available the first day of classes until the last day of final exams for the semester. Main campus lectures are recorded live and made available to students to view through streaming within four hours after recording (with the exception of a few courses).

If you would like to keep the course lectures, be sure to download the recordings to your computer by the last day of final exams for the semester. A fee will be charged for access to the recorded lectures after the semester ends.
