The SAT does not focus on raw scores—i.e. the number of questions each student got correct. Instead, the SAT is scored on a scale of 400-1600. The scaled scores allow for consideration of the difficulty of each test, as some tests might be harder than others. Hence, the raw scores are scaled to fit a normal distribution curve, and the scores of a student thus reflect on how he/she is compared with other students who have appeared for the test.
You’ll have one score for Math, on a 200-800 scale, and one score for Evidence Based Reading and Writing, also on a 200-800 scale. The essay will not be factored into your overall SAT score, and will be displayed separately on the report. The essay is scored by two readers on three measures: Reading, Analysis and Writing. Each reader gives the essay a score between 1 and 4, for each category and the grades are then summed. Hence, the highest grade you can receive is 8, 8, 8, while the lowest possible score is 2, 2, 2.
