It seems like an ideal degree to take from a foreign country, as there are no residential schools and very few opportunities for final exams. I think you'll need to contact Student Services to discuss your options, though, as there's not a tremendous chance that someone on the board has tried to take this course in a foreign country without checking first.
You might discuss with them the option of signing up for the individual modules under an Open Degree course, and then see if they'll switch you over to the named course once you have all of the modules out of the way. (It's possible that not all of the modules are available on the Open Degree course, however, especially as some of the Stage 3 modules appear to be in a current state of flux.)
If you have any questions about the K1, however, that I can help with. My wife went through the K1 eleven years ago. It was a snap, but a lot of waiting. And money. And photocopies. Congratulations.
