Should university students be required to attend classes? Sometimes I feel that studying alone seem to be more effective than attending the classes, especially, when I have a strong interest in a certain subject However, I disagree with the point of view that the classes should be optional for university students, because the function of the classes is never replaced by studying alone The main reason for my view is that we cannot learn all knowledge gained from the classes by learning the textbook alone Since the professor had studied his subject for many years and had spent much times to prepare the class There muse be some knowledge that are distinctive and cannot be gained from the textbook Furthermore, the professor knew which knowledge was very important, which can be skipped, and carefully arranged the schedule Studying as the schedule should be more effective Another reason for my view is that we not only can learn some knowledge in the classes but also learn the team spirit, the discipline and routine In the classes, we often discuss with other students, sometimes we even cooperate with others to accomplish a project So we have to learn to get along with others and train our team spirit Regular attending the classes also can let us used to routine and obey the discipline All these characters are very important for our coming jobs So based on all these reasons and examples, I think university students should attend the classes and that cannot be optional
