SAT:

The SAT (formerly known as the Scholastic Assessment Test) is a standardized test used by colleges and universities in the United States as an admission requirement. The exam is designed to measure a student's academic readiness for college and assess their critical thinking, problem-solving, and analytical skills.

The SAT is offered seven times a year in the United States and six times a year internationally. The exam is administered on paper or on a computer and consists of four sections: Reading, Writing and Language, Math (with calculator), and Math (without calculator). The Reading and Writing and Language sections are combined to give the Evidence-Based Reading and Writing (EBRW) score, while the Math sections are combined to give the Math score. The exam also includes an optional essay section.

The SAT is scored on a scale of 400-1600, with the EBRW and Math sections each scored on a scale of 200-800. The optional essay is scored separately on a scale of 2-8. The exam takes around 3 hours to complete (including the optional essay section).

Students can prepare for the SAT using a variety of resources, including study guides, online courses, and practice tests. The SAT is administered by the College Board, which also provides official study materials and practice tests. The SAT is widely accepted by colleges and universities in the United States and is considered a reliable measure of a student's academic abilities.
