Nope. I haven't yet, but I'm not due for my third for another 6-7 months I think.
But I've been assured by my school that when that time comes, at the very least I can get another 2 years if I just show I enrolled in the St. Theresa program.
So they said I could pay the initial fee (like 25,000 or something) and just not show up to any of the classes if I want to get another 2 year waiver. But obviously this is not a long term solution...
