I don’t think it’s too early.

It’s better to lay the foundation early. If you want to go to an American university, you have to take the SAT. The SAT takes math, reading and other tests - I don't remember clearly, but you can't fail in the basic courses anyway. You can take the TOEFL test many times, but of course the registration fee is very expensive. However, if you take the TOEFL five times, you can choose the highest score when applying to an American university, and the TOEFL score can be retained for several years. Some high school students have just finished taking the TOEFL, and then go abroad for one or two years of college in China. Their TOEFL scores will always be useful. I forgot how many years it can be kept. . . Sorry, TUT, I suggest you go abroad after your first year of high school. The United States has four years of high school, but the first year of high school is equivalent to the third year of junior high school in China, so you will be a top student when you go. You have to learn math well - really. The mathematics level of American high schools is a bit like the level of junior high schools in China. PS: For reference only. .
