mathematics
American mathematics is generally taught in the order of basic algebra-geometry-advanced algebra-calculus preparatory course-calculus. Generally, after finishing junior high school in China, you can take the calculus preparatory course directly, which mainly involves some functions (especially trigonometric functions). Completed the pre-calculus course and theoretically completed the high school mathematics. Then you can take courses like calculus. Calculus belongs to AP class, which means advanced placement, and refers to the basic course for freshmen open to senior high school students.
English English
American students have at least one hour of English study time every day from elementary school to high school. Students with good English can read novels in the fourth grade of primary school, and their vocabulary is almost 20 thousand. China students can adapt to oral English and listening in 2-4 months, and their literary literacy and reading speed will be gradually cultivated. It is suggested to take some general courses or ESL in the first year and intensive courses such as American literature in the second year. English literature, classical literature, contemporary literature, English writing and literature should be selected in the eleventh and twelfth grades. In addition, I would like to remind you that English skills are not only the basis for learning other courses, but also a strong guarantee for completing the report at ordinary times. Reading and writing are also items for applying for the SAT and ACT exams. I suggest that students must study hard.
Natural science science
The natural sciences in the United States are mainly divided into three categories: physics, chemistry and biology. The general requirement is that all three subjects must be completed before graduation. Every course has an honor course, which is faster and more difficult than regular courses. Those with excellent grades can consider taking AP course in the second year, which is equivalent to the basic course of freshman. Among these three courses, AP chemistry is the simplest, and physics and biology are neck and neck. AP physics is divided into B and C. Unlike AB and BC in calculus, the difficulty of physics B and C is quite different. B it's just an upgraded version of honor physics. It can be said that as long as you learn honorary physics well, you can pass the exam of B, while C only involves mechanics and electromagnetism, and solving problems requires calculus. Most of electromagnetism has nothing to do with China, so it is quite difficult. In fact, AP biology is far less difficult than physics C, but for foreign students whose English is only a second foreign language, there are many reciting contents and complicated technical terms. Suitable for those students who study hard and have excellent memory. To say that AP biology is a science is actually more like a liberal arts than chemical physics. Also, for students studying AP biology, they usually need to study honorary biology abroad for one year, because the foundation passed on to us as an elective course in biology in China is still very weak. However, for students who want to take AP physics and chemistry, as long as they have the foundation of senior one in China, it is no problem to take these courses directly. In addition, AP environmental science is also taken by many people.
