Find the raw scores for the math, critical reading and writing tests. For multiple choice questions, you receive 1 point for correct answers and 0 points for unanswered questions. For multiple-choice questions 1/4 point is subtracted for incorrect answers on a 5-choice question, 1/3 points for a 4-choice question and 1/2 point for a 3-choice question. Two readers grade your writing section from 1 to 6, combining to give you a 2 to12 score.
Find the section grades for the math, critical reading and writing tests. These scores range from 200 to 800, scaled by a computer. A score of 800 represents receiving the maximum amount of points for all questions. These 3 section grades added together produce your total score, which can range from 600 to 2400.
Read the score range for each of the tests. This is a statistical measurement that represents how you might perform if you took the test repeatedly. Usually your results from any individual test fall within 30 to 40 points of your true ability level.
Read your percentile, which is a number such as 71. The percentile shows what percent of students who took the test did worse than you. For example, a percentile of 83 means you did better than 82% of the students who took the test. The average score for each section is around 500 points.
