I'll throw WGU into the mix, there are many instances of someone completing their bachelors in 1 or 2 six month semesters, at $2890/semester...of course it depends on what you bring to the program and how much time you have to keep cranking out work. There are many reports of folks finishing a WGU MBA in a single six month term, at $3250 this may be the cheapest RA masters option available. In theory one might be able to get through the MBA/Masters level for $6140 and in only 1 year. TESC and COSC have BS/BA degrees that could be done for well under $5000...I think this would be more flexible than WGU, but not quite as cheap. I once considered the MA-Teaching at Morningside College using VESI courses...I believed, at the time, I could do it for $5000 and in one year.
