I think the most important thing is to study your professional knowledge in college, do outdoor activities well, don't go to Internet cafes and indulge in online games.

I have a high school classmate who chose to apply for the police academy after the college entrance examination. He is now an excellent police academy student. He told me that he never played games at school, and he often went to the library after studying well in professional courses. In the library, he can read a lot of books and improve his quality.
