Give yourself to diligent study and you will certainly succeed." Listening to my mum's words, I saw the light suddenly. I decided to start studying hard. Then, I got up early to review lessons every day. I listened carefully in class. I asked teachers for help as soon as I had questions. And I beat down the difficulties. A few days later, I succeeded in the next exam.
