Obtain your score report. The College Board will mail it to you a few weeks after the test date, and it will be accessible online. The score report lists your raw scores, scaled scores, percentiles and composite score.
Look for your raw score. It is the number of correctly answered questions minus a 0.25 guessing penalty for each incorrectly answered question. Hence, your raw score will be 25 if you correctly answered 26 questions but missed 4 questions. You will have three sets of raw scores -- one for each section.
Near the raw score is a column stating number of omitted questions; there is no penalty for omitting questions.
Find the column that lists your scaled scores. The College Board converts the raw scores to scaled scores, which range from 200 to 800. The scales vary from test to test, and each test has its own conversion table.
Find out how you performed compared to other students. Near your raw scores is a column that provides your percentile. If you scored in the 87 percentile, for example, you performed at the same level or better than 87 percent of students who took the exam.
Locate your composite score, which ranges from a minimum of 600 to a maximum of 2400. Adjacent to the composite score is the percentile, which shows how your total score compares to other students nationwide.
