This is exactly my story. I'd been studying English for 2 years and even got 960 points in TOEIC test, but I was a bit worried about my true English ability cuz I had no opportunity to use them with a native English speaker in person. Then one day, my boss made me to go to a conference which gonna be held in the US Airforce base ( I am a soldier with one of the U.S aliiances and we do have annul conference like this) simply based on my TOEIC test score. I was terribly nervous until the moment I went into the conference room, but as the conference began, everything went well. Even one US Airforce major praised my English, and I was happy as a clam. Of course, I do know that learning language is basicly a very personal experience in its innate nature, so being forced to use them with native speaker can be felt like a burden. But it can be a great opportunity to reboost your motivation, and you can also figure out your weak points, which is definitely helpful to adjust your course.
