SAT2考试是SAT subject test的通常说法。SAT2考试有别于SAT1，它是一种专项考试，考察学生某一科目的能力，故又被称为SAT SUBJECT TESTS。目前SAT2分为数学、科学、语言、英语、历史与社会科学五大类。下面为大家分析一下SAT数理化这几个科目的具体要求：
SAT2数学考试要求：
Mathematics Level 1 or Mathematics Level 2. Both mathematics tests consist of 50 multiple-choice questions. However, there are some differences in content.
– Mathematics Level 1 is designed for students who have taken three years of college-preparatory mathematics, including two years of algebra and one year of geometry.
– Mathematics Level 2 is designed for students who have taken more than three years of college-preparatory mathematics: two years of algebra, one year of geometry, and elementary functions (precalculus) and/or trigonometry. A student who has had preparation in trigonometry and elementary functions, has attained grades of B or better in these courses and knows when and how to use a scientific or graphing calculator should select Mathematics Level 2.
SAT2物理考试要求：
SAT II Physics is a one-hour-long test composed of 75 questions and divided into two parts. You can answer questions in any order you like, though you’re less likely to accidentally leave a question out if you answer them in the order in which they appear. Part A—classification questions—takes up the first 12 or 13 questions of the test, while Part B—five-choice completion questions—takes up the remaining 62 or 63 questions.
SAT2化学考试要求：
The SAT Subject Test in Chemistry contains three types of questions: classification questions, relationship analysis questions and five-choice completion questions. The relationship analysis questions differ from multiple-choice questions in their directions, presentation and answer requirements on the Subject Test answer sheet.
