Nowadays, taking ‘a gap year’ is the popular choice for undergraduates who recently graduated from high school. A gap year is a time between graduation from high school and starting at the academy; pupil can make their own decision about what they want to do in their future; as well as gain some experience doing something away from study. Working is one of the popular options for students because they can have time to think more about themselves by trying various places, not only the subjects at college, also have more understanding of the value of money and learn how to manage their own finances. Finally the practical experiences that they learn from their workplaces can not come from any theoretical backgrounds. My essay will focus on reasons with detailed explanations about why students should work before starting university.
