SAT2, also known as SATII, or SAT Subject, is an academic level test adopted by American universities when recruiting high school freshmen. The SAT2 exam adopts a global unified examination paper, so its results are globally comparable, which is an important reference for measuring the academic level of students in different regions. It often replaces high school transcripts in the actual operation of admission. Different from SAT's comprehensive ability test, SAT2 is a special level test, which examines students' level in a certain subject.

SAT2 subjects are divided into five categories: mathematics, science, Chinese, English, history and social science.

Math: Math 1, Math 2;

Science: physics, chemistry, biology;

Language category: French, German, Spanish, Chinese, Japanese, Korean, Hebrew, Latin, etc.
