Emptyinside, I prefer online courses because I have two handicapped children to care for, as well as my handicapped cousin, on top of the normal wife and mother household duties. It is difficult for me to schedule classes around my sons' therapy appointments and frequent illnesses. With online courses, I can do coursework after the boys are in bed. However, it does take a great deal of self-discipline and, when class is in session, I do spend time "in class" doing school work seven days a week. It takes as much time as taking a class in person.
You can do it. I always remind myself that if some 17 or 18 year-old kid whose never had a real job, had to create and live within a budget, or balance a checkbook can do it, surely I with my years of life experience am at least as smart at they are! You'll be fine.
I don't know where you live but here in Ohio, I've taken online courses from Miami University (Oxford, Ohio) and the University of Dayton. I'm also considering a few online classes offered by Sinclair Community College (Dayton, Ohio). These are all nationally known, accredited universities with reasonable tuition rates. I chose these schools because they are close by in case I need assistance and because I get in-state tuition rates. Even online, if you're out of state, you have to pay the higher out-of-state tuition rate. Check out the universities and community colleges within 50 miles of you. You'll have to take some placement exams in order to initially enroll but don't let the initial paperwork intimidate you. It's worth it in the end.
