Before you go to college, whether in middle school or primary school, there will always be a teacher to supervise your homework and class attitude. But in college, as long as you don't go out of line in class, the teacher won't care about you, which leads many students to be careless in class and think that it doesn't matter if the teacher can't care about you, but this is not the case. In college, only you can control yourself and restrain your desires, which is the most important thing.

2. Poor concentration

In college, we will be completely separated from our families, live in dormitories, and get along with roommates is inevitable. We spend most of our time with them, so we are easily influenced by them. If your roommate is in the library most of the time, congratulations, you will also be driven to study in the library. If your roommate dies in the dormitory most of the time, you are likely to waste college time in the dormitory, so choose one with the same ambition.
