University students are usually regarded as adults, so they are given more freedom than high school students. They choose their classes according to personal interest and schedule. Even they do not have to go to school if they
do not want, but that is not saying that they can do whatever they want without regulations. Basically, they can do what thwy want but they also have a responsibility to their actions. I would agree with the university student should
be attend classes because attending a class is another way of keeping a promise and they can learn subjects more effectively.
To beign with, taking a class is a kind of promise with the university. Keeping a promise is very fundamental and important in the social life. Our lives are consist of small and large promises. A class could be a importnat promise, so students can learn about keeing the promise with going to the class on time. Even some strict professors give bad grade to the student who did not attend the class or were late regulary, for instance, wong gun Kim, very famous music professor and tenor, punishes a student severely who is late because the musician should not be late at the concert. According to him, keeping the promise is important as well as raising singing skill, so the university student should attend the class on time to keep the appointment.
As a second point, student can learn fast with attending a class. Even if a student is really smart, there is a certain limit to study alone. That's why school and class are exist. Professor is professional in his field, and there are many classmates who share same aim with the student, so if he has a very difficult problem, he could ask to the lecturer or his classmates. It is very efficient. Even if the professor does not know the answer, it is still efficient because all class could ponder over that problem. If the student do not use very useful systmes to learn, it would waste of time and money even the konwledge.
In conclusion, attending a class is basic to the student because class is a kind promise with the school or teacher with the student,so he has an obligation to attend the class. It is very important altidude to live in the modern society, The student also extend knowledge more effectively than studying alone with sharing an idea and dicussing the problem. So I stronlgly recomend that student should attend the school.
