Which of the following is not a standardized exam for graduate school?

The SAT is primarily designed for undergraduate college admissions, making it distinct from the other exams listed. The GRE (Graduate Record Examinations), LSAT (Law School Admission Test), and MCAT (Medical College Admission Test) are all standardized exams specifically tailored for graduate-level programs. Each of these tests serves a specific graduate field: the GRE is used for various master's and doctoral programs, the LSAT is focused on law school admissions, and the MCAT is geared towards medical school. In contrast, the SAT evaluates college readiness for high school students seeking admission to undergraduate institutions. This differentiates the SAT from the other tests, which are essential for graduate school applications.
