My statement

My name is Bill Liu. I want to study in the University of Hong Kong. I am good at math. Though my English is not so good, I am confident to get over it.

I have became interested in computer ever since I touched my mother's Great Wall(a brand of computer).My mother was a computer programmer, I often watched her working on it when I was a child and I thought the work was interesting very much. Since then I have a computer programmer dream.

I know if I want to be a wonderful computer programmer, I need to study at a university who has international environment and open academic atmosphere. When I was a high school student I heard that The University of Hong Kong was a great school. It is a dynamic university. And it has all what I need. So I want to study in it.
