When I first saw this and realized that it was 9 courses long plus a capstone project, I was really excited! Then looking a bit more deeply, I see that they are 3-4 hours/week each and each is 4 weeks long. Though they recommend taking them in order, if you look deeper, it's pretty clear that you can take the first 3 in one batch, the second 3 in another, and the third 3 in another batch. That's 12 weeks at 9-12 hours/week... or, basically, the equivalent of one university class... for $490, which is about the price of paying per credit-hour for a 4 unit course through an average extension program at a public university. It will probably be great quality, but don't expect to have "credential-level" knowledge after taking it.
