Students are generally able to access course sites from the current and one previous quarter (unless the instructor has made a current course unavailable to students, or an older course site available again).
Students are strongly encouraged to download and save offline any course materials and copies of their own work that they may want or need in future quarters.
Students who need to access a course site that is no longer available to them should contact the instructor of the course in question. Students should request to be added to the course site as a Test Student so the instructor does not have to make the site available to all students.
