University is a place to exercise before you enter the society. A student who has just entered the university from the college entrance examination is still in the period of struggling for the college entrance examination in high school. What he knows about his classmates and teachers is his impression of high school. However, most things in college are different from those in high school. Teachers in universities will not teach you as carefully and patiently as teachers in high schools. You have to explore and understand everything by yourself, and you have to learn to study independently, which is one of the manifestations of independent ability. Secondly, communicate with people and make friends. High school is full of books, and there are not many strangers. In college, you must learn to communicate with people and learn to meet strangers by yourself. Only by exercising your ability to make friends and coming out of society can you adapt to all kinds of people in society more quickly. Finally, you will learn something about dealing with people in college. You must try everything in life. Only when you have tried, will you know what some values, outlook on life and lifelong beliefs are. Therefore, college is a period of personal growth and expansion, so make good use of it. Youth is gone forever. For reference.
