The university plays games in the dormitory and can't find a job at Harvard! The key is to rely on your own consciousness. To put it bluntly, if the school is "garbage", if you don't study hard, you will know to stay in the dormitory, and then it will be "garbage" in the school. Many schools have "garbage", but many schools don't deal with it well.
The most important thing in university study is how to study and form good habits. After school, I spend my time studying what I am interested in, and then expand my interpersonal circle.
