      A good way to pass an examination(考试) is to work hard every day in the year. You may fail in the examination if you are lazy for most of the year and then work hard only a few days before the examination. If you are taking an English examination, don’t learn only rules of grammar.

      Try to read stories in English and speak in English whenever you can. A few days before examination you should start going to bed early. Do not stay up late at night studying and learning things. Before you start the examination, read carefully over the examination paper. Try to understand the exact meaning of each question before you pick up your pen to write. When you have at last finished your examination, read your answers, correct any mistake that you see and make sure that you have not missed anything out.
