Dear Mr. Wise,
I'm a slow student. Most of my classmates are much better than me, so I usually get stressed out. Although I spend much time studying for the tests, I can't get good grades. Sometimes my father gives me some help. He tells me not to worry about it, but it doesn't work. What do you think I should do?

Dear Li Lei,
Many famous people were not so good when they were young. Edison, a famous scientist, did poorly in his studies when he was a young boy. But, as an adult, he made many inventions that helped a lot of people. When I was at young age, I didn't do well at school. I just kept working hard, and at last, I succeed. You should take it easy and try your best. Tomorrow is another day. I believe you can do better.
Mr. Wise
