SAT Reasoning Test is a standardized test for college admissions in the United States. The SAT is administered by the not-for-profit College Board corporation in the United States, and is developed, published, and scored by the Educational Testing Service (ETS).
SAT consists of three major sections: Mathematics, Critical Reading, and Writing. Each section receives a score on the scale of 200–800. All scores are multiples of 10. Total scores are calculated by adding up scores of the three sections. Each major section is divided into three parts. There are 10 sub-sections, including an additional 25-minute experimental or “equating” section that may be in any of the three major sections. The experimental section is used to normalize questions for future administrations of the SAT and does not count toward the final score. The test contains 3 hours and 45 minutes of actual timed sections, although most administrations, including orientation, distribution of materials, and completion of the biographical sections, run about 5 hours (10–25 minutes per each section) long.
