I am in the ninth grade in American high school. My sister and I went out together in the second grade. She is in grade 12 now. Because she came here this year, her English level was not bad before, but it still put a lot of pressure on me. Because 12 grade has a lot of reading and writing, and the requirements are very high, it is really difficult if you don't start from high school. Because not only to adapt to the language, but also to cope with the SAT. In fact, I suggest you come to the language school ESL, so that your SAT and TOFEL scores will be improved a lot. Because everything in American high school is simple, and you are a senior two in China, except American history, everything is simple for you. According to what my sister told me, students applying to American universities have to take the SAT, and foreign students have to take the TOEFL. If you want to apply for a good university, I suggest you take another SATII and ACT. Good universities in the United States value this thing very much.
