The SAT (formerly known as the Scholastic Assessment Test) is a standardized college admissions test that measures a student’s readiness for college-level work. The test assesses a student’s knowledge and skills in reading, writing, and mathematics.

The SAT has four sections: Reading, Writing and Language, Math (with calculator), and Math (without calculator). The Reading and Writing and Language sections are scored on a scale of 200-800, while the two Math sections are combined for a maximum score of 800. The total SAT score is the sum of the scores from these four sections, with a maximum possible score of 1600.

In addition to the main SAT, there are also optional essay and subject tests available. The essay test is scored separately from the main test, and the subject tests measure a student’s knowledge in specific subjects such as Math, Chemistry, or Physics.

The SAT is widely used by colleges and universities in the United States as part of their admissions process. It is typically taken by high school juniors or seniors, with scores being sent directly to the schools to which the student is applying.

Preparing for the SAT can involve studying materials provided by the test makers, taking practice tests, and working with tutors or taking courses. There are also many resources available online to help students prepare for the SAT.
