Basically, it is compulsory one and compulsory two in high school textbooks.
Many Chinese mainland students chose SAT II Math 2. As far as difficulty is concerned, the absolute difficulty of SAT II mathematics is far less than that of domestic high school courses. The following knowledge points are not involved in the high school mathematics curriculum, and candidates need to prepare for the exam carefully: finding the asymptotic line of fractional function, part of the round table probability model of probability theory, simple matrix in linear algebra, and zero point of polynomial function. The rest of the knowledge points are involved in the domestic high school curriculum. As long as you have taken the SAT I math exam, you can recite about 20 math terms (asymptote, parabola, focus, etc.). As for whether to bring a powerful TI calculator, I personally think you can bring one if you can, but if you can't, don't worry, because as long as you master the basic solution taught by the teacher in class, you don't need to draw an asymptote with a calculator. Mathematics is relatively easy, so it is suggested that Barron's published reference materials are enough, and then do a set of OG topics and be familiar with the questions. Questions that can't be done in the examination room can be given up, because there is still a great possibility of getting full marks within a few wrong questions. Pay attention to time in the examination room. When doing the problem, try to use a simple way. If a problem is complicated or has no clue, give it up quickly. For the mathematics of SAT I or II, it is the problem-solving principle: the simpler the method you use, the greater the probability that you will get the problem right. SAT II physics: recommended books Barron's information. As far as the difficulty is concerned, the physics of SAT II is far less than that of domestic courses. The following knowledge points are not involved in physics classes in senior high schools in China, and candidates need to prepare carefully: quantum mechanics and nuclear physics (chapter 2 1 of Barron's book). Candidates don't have to memorize physical words deliberately, because if you are good at physics and then pass the SAT I exam, then basically, physical words are easy to recognize. Physics questions are basically conceptual questions, and the amount of calculation questions is very small, but the way of setting questions is very different from that of domestic high schools. Moreover, the length of the real question is longer than that of Barron's exam, so the reading speed of candidates must go up. Candidates are advised to do more questions and summarize at the same time. Because of the wide knowledge range of physical design, candidates must be familiar with the related concepts and principle derivation of the wrong topic domain. SAT II chemistry: recommended books Princeton Review and Barron's book. For many students, compared with mathematics and physics, chemistry has a great feature-wide but not refined, that is, it has a wide range of knowledge and involves almost everything, but every knowledge point is not refined. As far as the absolute difficulty of the topic is concerned, it is far less than the difficulty of the domestic high school chemistry exam. As for the names of the periodic table of elements and other chemicals that need to be memorized, you don't have to spend time memorizing them. The chemical contents that are not involved in domestic high schools are: chemical equilibrium and its influencing factors, thermodynamics and energy conversion. These parts require candidates to read the principle and its application carefully. Candidates are advised to do both sets of questions above. At the same time, compared with physics doing 75 questions an hour, chemistry doing 85 questions an hour. Therefore, candidates must master the basic principles and concepts of chemistry very clearly.
