SAT II
Subject Tests are one-hour, primarily multiple-choice tests in specific subjects. The Subject Tests measure knowledge or skills in a particular subject and your ability to apply that knowledge.
They are used in combination with other background information (your high school record, scores from other tests like the SAT I, teacher recommendations, etc.), to provide a dependable measure of your academic achievement and are a good predictor of future performance.
