1. The SAT for studying in the United States is a compulsory test for American high school students to enter American universities. Its importance is equivalent to the college entrance examination in China, and it is also an important reference for high school students all over the world to apply for undergraduate courses in American universities and get scholarships. In fact, SAT is divided into SAT 1 and SATII, in which SAT 1 is divided into three parts: mathematics, reading and writing, with 800 points for each part. SATII is divided into five categories: mathematics, science, language, English, history and social science. Among them, there are Math I and Math II, Science III, Physics, Chemistry and Biology, and twelve languages, such as French, German, Spanish, Chinese, Japanese, Korean, Hebrew and Latin. English is only English literature. History and social sciences, including American history and world history, add up to 20 exams. China students have a unique advantage in SAT math subjects, and often get high scores or even full marks, but they are slightly poor in writing. Ivy League admissions officials said that writing is not only an inspection of English use, but also the most effective inspection of a person's ideas, and also an inspection of this person's logical thinking ability and language organization ability, which is what China students lack. There is no SAT test center in Chinese mainland, and mainland candidates mainly go to Hongkong to take the SAT test seven times a year. SATI and SATII can't take the exam at the same time, so if you choose SATII, you have to go to Hong Kong twice. 2.ACT (American College Exam) is an entrance qualification examination for first-year undergraduate students in American universities, and its scores have been accepted by more than 3,000 universities in the United States as undergraduate admission standards, including Ivy League universities such as Harvard University. ACT exam is more like a subject exam, which emphasizes the examinee's mastery of course knowledge and also gives consideration to the test of the examinee's independent thinking and judgment ability. The AP exam is even different. The AP exam can be regarded as a credit conversion exam. Biology, calculus, chemistry, economics, psychology, history, etc. in AP exam are all freshman courses, and they can be directly converted into credits after learning. 3. AP exam for studying in the United States AP exam is a prerequisite course for American universities, which is suitable for high school students who plan to go to the United States to study undergraduate courses all over the world. Sponsored by TheCollegeBoard, AP scores can not only deduct credits for students who successfully apply for American universities, but also become an important basis for American university enrollment. At present, AP test has been recognized by more than 200 universities in the United States, including many ivy league schools. When applying to a top American university, every student will submit the corresponding AP test scores, ranging from 3 to 8 to 10. For example, 1 150 students submit 569 1 scores to Yale University, with an average of 4.95 courses per person; Other schools are: Swarthmore College 4.738, Columbia University 4.692, Dartmouth College 4.688, Williams College 4.64, Princeton University 4.63, University of Pennsylvania 4.605, Pomona College 4.438 and California Institute of Technology 4.4. The three types of exams for studying in the United States have their own advantages in the admission of American universities. Some schools value SAT scores, while others look at AP scores of several subjects, but in the final analysis, these three types of exams focus on examining students' academic ability and comprehensive language use ability.
