Ten years ago, I was in greatly depression. I worked hard at piano learning and devoted all my spare time to learn it. But I failed to pass the B level test, that made me quite disappointed. So I turned my mother for help when I got home. Hearing of what I told her, she smiled, “Test results sometimes cannot real show your ability and level. Thus, my progress should not be judged only by one test.” She encouraged me to work hard for the next year’s B Level Test. I take my mother’s advices. Now the B level test is in front of me, and I’ve realized that the process of learning is much important.
