In my understanding, if we refer to an ideal college life as a formal western dinner, then a high GPA, that is, Grade Point Average, should be the main course, while an active part in activities, together with associations, means the appetizer. Some romances, of course, play the role as desserts. They are the 3 key elements for an ideal college life.
Those, however, are not what college life is all about. As we all know, college is wildly different from middle school. It connects not only adolescence to adulthood, but also the ivory tower to the real society. Therefore, the ideal college life is that I become matured both physically and mentally, and that I obtain qualified academic knowledge and get well prepared for society at the same time.
