Of course, college students should be independent and have the ability of self-thinking, so that they can really judge whether the classroom can be completely absorbed by themselves and have more meaningful things to do. For example, they always go out to do business and make systematic websites for some outside enterprises, so they skip classes and run out. In the end, their test scores were good, and they gained a lot, which improved their professional level and cognitive ability to contact the society. To a great extent, I cultivated my independence in college.
