Yes and no. All classes need to be completed during the semester in which they
                           are taken. However, the pace of a class depends on what 
types of online class you take. In traditional online classes, you have regular deadlines for course work,
                           but you can complete the work for those deadlines whenever it is convenient for you.
                           In CBE (competency-based education) classes, you have a suggested pace but can acceralate
                           your progress if you would like.
