There is info (some of which is listed below) at the flwg link: www.dbu.edu/academics/policies/credit_hour.asp qte . . . . Credit Hour
The credit hour is the basic unit of measure for college credit. Most courses at Dallas Baptist University are offered for three semester hours of college credit. This means that the student invests the equivalent of three hours per week in the formal instruction process for each three-hour course. The student should invest much more actual time than this for each three-hour course in order to complete the necessary library and preparatory work for formal instruction periods. Laboratory classes are exceptions to this example as are certain music classes and other classes that require the development of various skills. . . . . unqte More at the supplied link. Hope it helps.
