It is normal to be tired in college, because unlike high school, college is more mentally tired than physically tired, because there are not many classes in college, but more complicated, such as letting you attend classes, participate in practical activities, hold activities of a certain club, or participate in some school organizations, which will find you. All kinds of idle and boring things can be said to be the above sentence. They just post something for you to do. In fact, this thing doesn't make much sense, but workers should adjust their mentality, which means you should understand what the university wants. If you want to take the postgraduate entrance examination, then you should concentrate on your own study and exercise well, and don't think about anything else, because when you become excellent, emotion is a natural thing for him, so you should recognize the essence of college life. These extra things you do at school are to improve your communication skills. But if you feel that these things have affected your normal life, then don't do it. Concentrate on your studies, improve your physical fitness, have nothing to do, and then let yourself have money to spend and have enough economic ability, and college life will be very happy.
