This is very important. This is where an on-line course can create a great deal of value. While traditional undergraduates are generally able to direct most of their energy toward their studies, older students, parents (especially single parents), and students who work full time have family and work responsibilities competing with school for their time, energy, and financial resources. Difficulties in obtaining child care and class schedules that do not mesh with work schedules are just two of the barriers that nontraditional students may encounter.
