First of all, you should determine whether you are a free normal student. If so, don't say any more. After graduation, I can only be a teacher (the state assigns me back to my hometown). If not, in Beijing Normal University, it is very easy to transfer to a department to get a double degree, so it is better to minor in psychology (the best psychology in the country). It is easy for you to take the postgraduate entrance examination or graduate study in the Physics Department of Beijing Normal University, but the situation abroad is not very optimistic. As for going abroad and physics, the United States is the first choice for going abroad, but the requirements and characteristics of foreign schools are different, so you should learn and choose slowly. In addition, college physics is different from high school, and it is more about contact. I believe you will still keep your interest in physics and learn this kind of science well in college.

By the way, as a senior, I have to remind you that the conditions of the school are limited, so be prepared psychologically.

You can search the Xixilou dormitory of Beijing Normal University from the Internet (it should be allocated there), and you will know)

The majors of information science and technology, resources and environmental science, environmental science, resources science and engineering, management science and information management, and information system you mentioned all have a certain relationship with physics, which means that if you take the postgraduate entrance examination, these majors like physics students very much, but these majors in Normal University are not very good.

From the professional point of view, the rate of physics going abroad is relatively high, but China University of Science and Technology and Peking University are the main places to study physics in China. As for the Physics Department of Normal University, the accreditation of foreign schools is not very good, and not many people go abroad successfully every year. The students of physics department of Beijing Normal University mainly apply for domestic graduate students. But it mainly depends on your own efforts, which mainly requires you to have your own highlights, such as excellent grades, excellent papers or club experience.

As for the preparatory class, I don't know much about it.

If you want to go abroad, you will generally apply for about 20,000 yuan (take 10 University as an example), but if you are admitted, there will be various scholarships and grants, so you don't have to worry about tuition and living expenses.
