Mathematics in America is very simple? I go to high school in America. In fact, the initial course may be relatively simple. Such as algebra 1 and geometry, that is, algebra 1 and geometry. But algebra 2 and pre-calculation are not simple. I go to junior high school. Let's summarize. Mathematics in the United States will not go deep into the corner like China, and it will be very tolerant, but I will learn a lot. What you learn in one year in China is often worth three years. Therefore, we should not take American mathematics lightly, but also study hard. Nothing is simple and not simple, so take it seriously. The harder it is, especially AP. Of course, English vocabulary is also very important, such as geometry. I remember we memorized a lot of words.
