Many people say that schooldays are the best days of their life, and they often feel that this should be a period of enjoyment. However, exams often make them unhappy, and many students prefer having no exam at all. They say the exams which they have to take often make them worried, and they have no time to relax. Others, on the other hand, say that exams help students study better. They will have to study throughout the year, and if they do well, they will become more interested in studying. There are some students who prefer only final exams. They say that they have to work hard for two months a year and so they have more time for their leisure activities. They think that this is a better way of assessing students' knowledge and ability in the subjects they are studying.
