I passed! 合格しました！
In December, I took the Japanese Language Proficiency Test (日本語能力試験).
Today, I finally got my result, I passed! After I took the test I thought that maybe I passed, but I was not sure. Actually, I did very well. I scored a 91%. The passing grade is 60% or above. I got a perfect score for the Reading and Listening sections. I am very happy with my result, because I didn't have a chance to study very much before the test. Ayumi was in the hospital last October and November, so I was pretty busy working at NEO every day.
I hope that people who read this will try to take some language tests. It is a good mental challenge and it helps to focus your studies.
