Hi! I would suggest you don't apply for S.Korea unless you can think of a compelling reason for choosing that country, because it is the only ETA program that is full teaching and although teaching experience is not mandatory, it is preferred. So if you can't come up with a compelling reason AND you don't particularly have teaching experience, I would choose one of the other countries! Just a thought. Personally, I didn't have a super strong reason to pick Korea but felt I could make the best argument for it, and I have educational experience. Hope that helps!
