In a web-based course, logging into Blackboard is the same thing as attending class. You must log in according to the schedule your professor sets or you risk not receiving credit for the class. Taking a web-based course has many benefits. For one, you do not have to come to campus. Some departments may not be able to offer evening classes, so if you work full time during the day, taking a web-based course will fit into your schedule.
All classes begin the first week of the term, and all have syllabi, schedules, exams, papers, etc.
