Stephen: Well, I was quite proud of my efforts there. I mean, I did prepare a lot for my classes to make them entertaining as well as educational but no matter how hard I prepared it all depended on the student. And especially in Japan where a lot of people, especially the men are quite shy to speak a foreign language, some people progressed quickly and some progressed slowly and some didn't progress. Typically the young women progressed much faster than the men because I think they didn't have as much pride or embarrassment. So it really depended on the student but I would say 60 to 70 percent of the students in a one-year period you could notice a definite improvement.
