Bear in mind that this calculator is based only on the 10 past curves that have been released—what you're getting is an educated guess. Do not think that your scores are an error just because they are outside the range of scores this calculator gives you. It's impossible to know how The College Board has been changing up the SAT exam and setting the curves for the many exams it doesn't release. Recent reports indicate that the curves are getting tougher overall at the top. For example, the June 2018 math section had an extremely harsh curve because it was much easier than usual.
Note: Because of rounding, percentages may not add up to 100. We do not take into account curves from sections that had faulty questions.
