2. The learning atmosphere, methods and mentality in the university are very different from those in the past. In college, you won't just play and be carefree like primary school, and you won't devote yourself to the study of college entrance examination like high school. But to exercise yourself in learning, socializing and skills. Just catching one of them won't make a difference. Therefore, the university is a truly all-round development period. Many people who used to be introverted will become another person in college. Whether it is good or bad depends on yourself.
It is normal for many people to meet the other half of their lives in college. Maybe you can find like-minded people there and spend your life together.
