The SAT (Scholastic Assessment Test) is a standardized test widely used for college admissions in the United States. It assesses a student's readiness for college and is typically taken by high school juniors and seniors. The exam consists of sections on Evidence-Based Reading and Writing & Math. Scores range from 400 to 1600, combining scores from the two main sections. It's important to prepare by practicing with official materials and understanding the test format. Many colleges consider SAT scores as part of their admissions process, though some have shifted to test-optional policies.
