Several problems about studying abroad.

First of all, you have made it clear that the purpose of going abroad is to improve your English and then go back to China for development. So I think Nordic countries can forget it, because countries whose mother tongue is not English, even using English for teaching, are not good for improving English. Because your budget is sufficient, you can consider Britain, the United States, Canada, Australia or New Zealand (University of Auckland).

Secondly, domestic high school culture classes are of little help to studying abroad. So as long as you have a high school diploma and a high school transcript. Finally, I will talk to you about English.

Third, studying psychology abroad requires a high standard of English, which generally requires IELTS score of 7 points. It is difficult to meet the entrance requirements and it is extremely difficult to graduate. I suggest you choose another major. Hotel management or other business management, I think it is more suitable for you.

Fourth, because you need to apply for a student visa, and foreign universities generally require students to provide valid IELTS or TOEFL scores to accept your admission, so you must take an English test. I suggest you take IELTS, which is recognized by many universities in Commonwealth countries and the United States. If IELTS fails to meet the language requirements for school entrance after the exam, you can apply for a language school in the university.

Since you graduated from high school, applying for a foreign university will basically require you to study for one year in the preparatory course of a foreign university (the course is equivalent to a freshman in China, not the preparatory course of some cooperative schools), and you can only enter the school if your grades meet the requirements. Of course, some schools do not require it. But studying in the preparatory course is actually beneficial, which can improve your English ability. After all, schools teach in English, and students whose mother tongue is Chinese need to adapt to lectures and exams.

Generally, studying abroad with a student visa is to ensure class attendance. If you want to return to China on non-holidays, as long as it is not too long. But it is best not to exceed 1 week. Otherwise, you need to write a written application for leave to the school. However, there are many holidays abroad. Basically there is a small holiday every two months, and Christmas and Easter are big holidays.

Finally, talk about English learning. As your foundation is weak, you'd better sign up for an English class from scratch. Of course, teachers of 1, preferably 1, can make study plans according to their own progress speed. I think your goal now can be to learn the new concept 1 and volume 2 in two months. Master some basic English, and then start preparing for the IELTS test. Good luck ~ ~
