I wrote in my first article that my supervisor was an American once, but actually, I seldom spoke to him in English. He of course hired an interpreter, so I didn't have to speak to him in person. And honestly, I was a freshman in the office at that time, so there was no need to report to him directly. As a freshman, I had to attend some training sessions held in English and it made me motivate learning English. There are some staffs who could speak English at every section in the office, so I had strong feeling to master English. However, the supervisor returned to the U.S. next year and there was no urgent to use English. That's why my English hasn't improved enough to conduct some operations at the office. I don't have any experience studying abroad, so honestly I feel a bit embarassed when I face to some English speakers. So English conversation schools are of some help to me feeling confident facing English speakers, even though some may be dubious about the effectiveness of them. Honestly, I'm still interested in NOVA, and other schools. When I can pass the first-stage exam of the STEP 1st-grade test, I'll go and take some interview tests at schools.
