It is a really inexpensive way to get a good degree. The one caveat is that they already have determined the classes and the courses you just choose what order you go through them in. For example I am currently getting my masters, and someone has posted how they managed to knock out the entire degree (8 semesters) in 2 months. (The disclaimer was he had worked in the field for close to 10 years in various positions, so everything in the degree was second nature)

I got my degree in 18 months, plus one semester of a local college prior. But yes if you've got the discipline and motivation you can get your entire degree in 6 months for about 4 grand.

It really is the way of the future in my mind.
