2. Isn't high school boarding? It's always the first time for that person. At first, he will be homesick. I remember that although I was far from home (the university was not too far from home), I had the opportunity to go back. Later, when I got used to it, I was too lazy to go back. Call home and say I'm safe People always leave home, leaving early and leaving late. Self-reliance is not a big problem for you. Besides, universities now. If you can't do your own laundry, there is a laundry room. The main problem may be food. For example, if you go from the north to the south, what you are not used to is food. Just get used to it. If you study, as long as you are not too stupid at first and very, very diligent at second, you will definitely earn those credits.
3. I think the student union and the community mainly depend on your personality. You are extroverted, good at communication, and have certain management ability and eloquence, so you are the material of the student union. If you are introverted, I think you'd better forget it.
TOEFL mainly depends on your own wishes. It also depends on your English level. Ha ha.
Don't worry about transferring to another department. As a high school graduate, you won't return high school math and English to your teacher within six months. It's okay.
Actually, our generation is different from the older generation of college students. High school teachers often say that you have already moved into the university in advance. After I go to college, it really makes sense. I feel that there is no difference between high school and college. It's just that there is a little less class time (going or going), the leaders talk less and there are more extracurricular activities.
Between classmates, we are all adults, and we may not be as enthusiastic as we were in high school. (Especially for girls, it is normal for a dormitory to have contradictions. Maybe you treat others as friends, but others are ungrateful. The interpersonal relationship in the university is actually quite close to that in the society. Get used to it. Maybe I talked too much, but I still had many good friends in college.
5. Love. To tell the truth, high school love is basically fooling around. When you go to college, everyone will not be so blind. Especially in junior and senior years, they may also aim at getting married. In short, many people didn't find a partner when they were in college. Don't think that you must find a partner when you come to college. That's not true.
I wish you a wonderful college life.
