Were the FTD your classmates also? We all know that you should take the regional boards in your own school, since it's too hard to get acquainted with different equipments right away. The failure rate would be high between the American graduates too if they had to take the test in a school other than the one they attended. And we all know that you have to have the ideal patients and bla, bla, bla.
Another point to consider is that as FTD we can apply to a residency and then take the WREB to get a license. If you are trained in Oral Surgery for 4 or 6 years, who knows when you stopped doing crowns and so on. It gets a little tricky to be perfect in all that crap. Some of us can't pay schools or private parts for additional training/review of Operatory Dentistry and Prosthodontics. These guys can charge $15,000 for a review course.
Again, it's the American mentality...They think they know everything...
I've seen so many posts in the NBDE section of the site where the American school graduates are crying because they only got a 74 in Part I and others desperate because if they don't pass part II they can't graduate...I am talking about what I have seen and not about what someone has told me...
