Blackboard is an online teaching and learning platform that many of our course instructors use for their seminars or lectures. When you "enroll" in a class on Blackboard, you gain access to important course content uploaded by the course instructor. This usually includes readings, the syllabus, announcements, etc. You mostly will need a password to access this information. This password will be provided by the course instructor in class.
Please note that "enrolling" in a class on Blackboard does not mean you are officially enrolled for this class. For that purpose, and since you are not supposed to use Campus Management, you need to personally get in touch with the respective course instructor at the beginning and at the end of the semester.
