College life can bring you a lot. First of all, the university is a small society, from which you can understand many truths that high school does not have. The living expenses given by your first parents can help you learn to plan your money reasonably, and don't spend money indiscriminately, otherwise you will have no money, and you will have no money in the future. There are also many club activities, some of which are a waste of time and treat you as cheap labor. Some club activities can also help you learn something and meet some new friends, which may be an unforgettable experience in the future. Not all roommates can be friends in the dormitory. Some people will push their luck if you don't talk about her. Don't be too simple, recognize the reality, and speak out bravely if you have any questions, otherwise you will be really tired. In class, some teachers won't remind you to study. It depends on your own consciousness. If you don't study hard, you have to make up the exam. Make-up exams are troublesome. Listen more. The final exam score is a percentage of your usual grades. Don't play with your mobile phone too much in class. Don't deliberately maintain unnecessary interpersonal relationships, who cares whether you graduated from college or not, so make friends selectively, and don't think it's good to have a bunch of friends.
