I'm currently working on my bachelors and starting to investigate grad school. I'd likely be working full-time and paying out of pocket for my tuition expenses, so I've got to try to keep my costs down. In the short term, I'd like to get a masters and eventually enter a PhD program. How much am I really looking at for an inexpensive distance learning M.A. or M.Sc. degree from an accredited graduate program where I can acquire the skills to do research and continue on to a PhD (if I'm capable)? What's the range on tuition costs (perhaps an average $/credit hour)?
