The second is the preparation for study. In fact, studying in college is not easy. Maybe many teachers in high school told you that going to college is easy, but it's not. There is a lot of free time in college, but it's really stupid to waste it. You must use this time to study, you can recite English and read computer books. There will be many things and activities in organizations such as societies, associations and student unions, so please be prepared to study and be busy. College is not as easy as you think.
The third is to be prepared to get along with different people. College students come from all corners of the country and there are people everywhere. Maybe you just studied near home before, but when you get to college, you meet more people and get in touch with more people. Therefore, we must be more tolerant and patient with others in character, so as to get along well with others. The most important thing is to respect other people's nationalities or customs. Maybe there will be ethnic minorities among your classmates, so you must know their customs. Even if some behaviors are different from yours, don't point out others.
I hope your college life is happy!
