give me full information about SAT

SAT is a Paper-based standardized test that was engineered by the College Board, Educational Testing Service, the United States of America in the year 1926. The SAT is owned, developed, and published by the College Board, a private, non-profit organization in the United States. The test is designed to assess students' readiness for college. The SAT is typically taken by high school juniors and seniors. The College Board states that the SAT measures literacy, numeracy, and writing skills that are needed for academic success in college. They state that the SAT assesses how well the test takers analyze and solve problems—skills they learned in school that they will need in college. However, the test is administered under a tight time limit (speeded) to help produce a range of scores.
