SAT2考试是对考生分项能力的考察，而不是综合能力，所以科目比较多，有20门，一般考生可以选择2到3门参加。
sat2考试科目一共20门，分别是:
english(literature)
history(united states history，world history)
mathematics(mathematics level 1，mathematics level 2)
science(biology e/m，chemistry，physics)
languages(chinese with listening，french，french with listening，german，german with listening，modern hebrew，italian，japanese with listening，korean with listening，latin，spanish，spanish with listening)
其中，数学和科学类的几个科目是中国的考生最常选择的sat2考试科目，下面为大家分析一下这几个科目的具体要求:
the sat subject test in biology e/m contains a common core of 60 general knowledge, multiple-choice questions, followed by 20 multiple-choice questions that emphasize either ecological (biology-e) or molecular (biology-m) subject matter. before they begin their test, students choose either biology-e or biology-m. after completing the core questions, test-takers follow directions on the test to proceed to the section they chose.
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.
the sat subject test in 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.
