It was a good experience. You'd learn more in 4 years at a brick and mortar since you spend more time and homework there. Great option if you already know much of the material though, but i think they only admit US and Canadian people.
I liked that it was async but still proctored exams, and they provided great access to teachers and so on.
That's that idea out the window then! They should open up to international students, I reckon they'd clean up, the only real competitor in the UK would be the Open University and WGU has significant cost and time savings over it.
