  I'm a student of Grade 3.I have a problem. I am worried about my study all the time these days. I was one of the best students in my class. But last month we had an exam and I didn't do very well. I feel very sad.  think my parents will be angry with me. Maybe both my friends and my teachers will laugh at me. What's more I 'm always thinking about it in class and sometimes I don’t know what the teacher has said. I feel tired and sleepy in the evening when I do my homework.. As a result I do even worse in my study than before. What should I do? Could you give me some advice?

                                                                  Yours

Li Ying
