The university is relaxed, just saying that there are fewer courses of theoretical knowledge, and students have more time to do what they want to do. If he is a diligent person, he will find his hobby in college, stick to it and make unremitting efforts. Either join a community or participate in social practice to accumulate experience. Or go deep into your major and increase your knowledge.
What is better about college life is to give people space to play. I can't say that I am sloppy, but I have experienced the high pressure of high school life. In contrast, I feel more relaxed psychologically.
