Today I went to my piano lesons,after my piano lesson,my mother came to pick me back. When I finished my lesson, my teacher said something to my mother. Then my mother said she will help me about the music theory. On the way home, I asked my mother what did my piano teacher said to her, my mother said "You have already studied in grade 6. But you didn't discover the that you are studied in grade 6 because your piano teacher doesn't want you have more things to worry about. But you must pass your music theory test in next month,then your piano teacher will apply the piano form to me immediately. Then you will be a grade 7 piano student." After I heard this dialogue, I feel happy that I have already studied at grade 6. But I know if I don't work hard for the music theory, then I won't be the grade 7 piano student. So my god, I wish I can pass my music theory and go to grade 7.
