The SAT is a standardized test widely used for college admissions in the United States. It measures students' skills in reading, writing, and math, helping colleges assess a student's readiness for higher education. The test consists of multiple-choice questions and an optional essay, and it is typically taken by high school juniors and seniors. Many students prepare for the SAT by taking practice tests and studying specific content areas. Colleges often use SAT scores, along with high school grades and other factors, to make decisions about admissions. A good score can enhance a student's chances of getting into their desired college or university.
