A: SAT stands for "Scholastic Assessment Test" or "Scholastic Aptitude Test". It is a standardized test used in the United States for college admissions. The SAT measures a student's readiness for college-level work by testing their knowledge and skills in reading, writing, and mathematics. The test is typically taken by high school juniors and seniors and is used by colleges and universities as part of their admissions process. The SAT consists of multiple-choice questions, with an optional essay section. The test scores range from 400 to 1600, and the higher the score, the better a student's chances of being admitted to the college or university of their choice. Many students prepare for the SAT through practice tests, study guides, and courses offered by test prep companies.
