Maybe I haven't adapted to the learning rhythm of the university yet. The university doesn't study as hard as high school, and no one is in charge, and I have no motivation to study. Plus, my classmates are playing mobile phones to sleep, and I will be unconsciously affected.

Therefore, it is still necessary to adjust your state and set yourself a learning goal. Even if nobody is in charge of the university, you should push yourself. Usually you can go to the library to study more. There are many hard-working people who can be your role models.
