Don't worry, because the United States is not like our country, and you can take the SAT several times. Moreover, American universities attach importance to many other things, so we should carefully prepare the application materials. How to prepare the application materials, you should look at other American students more. If you speak a foreign language, you can try those training courses for China people. There are many in America, and then you should communicate more. Like China people, grammar is generally good, mainly vocabulary and spoken English. We can communicate more, and China people will be fine as long as they understand the topic.
