Helpful information. But, as far as getting really technical, they're based in South Africa, and the training and licensing on their part would only be good for South Africa.
However, extremely helpful, nonetheless.
I am wondering, however, why there isn't such a school in the United States (I would be certain that it would even cost less than doing it at a regular ground school or flight school, plus you won't have to drive anywhere). If there is such a school online in the US, please post!!!
