Generally speaking, if your English in high school is ok, you should have no difficulty in passing CET-4. If you want to take the postgraduate entrance examination in those good schools, it will be more difficult for you than those students in a college, but it won't have a big impact, because if the school is better, his teachers and professors will have a higher level of understanding, and he will pay attention to your real talent and learning, not those superficial things. This requires you to study hard at ordinary times, and it is best to publish some papers in some authoritative magazines. For example, our professional students in China Geo University have great advantages. Their magazines can be easily published in authoritative scientific magazines, because many of their teachers are academicians, so I suggest that you take your computer with you when you are in college to consult the information you need conveniently. In college, liberal arts majors really need to recite a lot of things, but it is necessary and plays an important role in your future development. Hehe, I am very lucky. If I study engineering, I suggest you have a good summer vacation. You can learn slowly when you get to college. Besides, studying is not this moment. As for foreign languages, it depends on your interest. There is no need to learn, but learning is always good. Those computer grade exams depend on what kind of computer courses your school will offer. I study C language, so you probably have to learn it, too. Textual research will not be too difficult. As long as you study hard, you will pass. There was also a requirement of CET-6 for postgraduate English. In college, time is relatively loose, and your tightness depends on yourself. I suggest you just choose a class committee. The so-called club activities are a waste of time. Don't expect too much from summer jobs, because freshmen and sophomores are basic professional courses, and you can only find some handicrafts, not those part-time jobs closely related to your major. I recommend you a way to find a part-time job, when you enter school. Well, that's what I'm talking about. I hope my junior can adapt to college life well! I wish you a happy college life.
