If you plan to go to the United States for further study in the future, I suggest you plan the first three years of college. The three most important points are:
1. Take your study seriously. Your final exam results are very important. Don't think you can adjust your report card in the future. That's not the case at all. Don't take such a risk.
2. If there are experimental or scientific research projects or internship opportunities, you must actively participate in them and strive to do several good projects and produce results. If you have the opportunity to publish relevant papers, you must get along well with professors and learn more with an open mind.
3.GRE and TOEFL are also very important. You must make preparations early. At least in my sophomore year, I will start preparing for TOEFL and GRE. Before the summer vacation of junior year, you should get ideal TOEFL and GRE scores.
Finally, pay more attention to some information about studying abroad, learn about foreign universities, the setting of this major and the research content of professors, and find yourself a dream school, so that you will be more motivated.
Come on, good luck!
