My dream

I want to become postal clerk. I worked part-time job at post office last winter vacation. In the post office, assortment of a postcard before delivering it was very hard. But I enjoyed oneself because all the postal clerk were very kind. when I worked at post office, I thought a task with challenge. So I want become postal clerk. But an examination of a post office is very difficult.Contents of a test are national language, mathematics, science, society and English. Then, there are an interview and a short essay, too. I want to do test study of a post office early.
