Dear Editor,

I am going to take the college entrance examination soon. I have to work harder and harder to prepare for it so that I could enter a good college. However, it’s hard for me to understand what my teachers say in class. Though I tell myself again and again I should hold on, I have little confidence in myself. What should I do now?

Best wishes,

Li Hua
