How the digital SAT is scored

The digital SAT has two sections: Reading and Writing (54 questions in two 27-question modules, 64 minutes) and Math (44 questions in two 22-question modules, 70 minutes). Each section is adaptive at the module level: how you do on the first module decides whether the second module is the harder or easier one. Your raw score is simply the number of questions you answered correctly across both modules; there is no deduction for wrong answers, so guess on everything.

Raw scores are converted to a 200 to 800 scaled score for each section. The conversion is not a fixed lookup: the College Board uses item response theory, which weighs harder questions slightly more and accounts for which second module you saw, and every form is equated so scores are comparable across test dates. The table below is a representative curve from the practice-test scoring guides, which is why the result is labeled an estimate. The total score is the sum of the two sections, 400 to 1600.

Reading and Writing score = table(RW correct)      200 to 800
Math score                = table(Math correct)    200 to 800
Total                     = RW + Math              400 to 1600

Worked example: 44 and 36 correct

With 44 of 54 correct in Reading and Writing, the table gives 660. With 36 of 44 in Math it gives 670. The total is 660 + 670 = 1330, which is about the 87th percentile of test takers. Missing one more Math question would drop Math to 660 and the total by 10; getting two more right in Reading and Writing would raise it to 680.

Raw score to scaled score conversion

Representative table based on College Board practice test scoring guides; actual conversions vary by form and by which second module you receive.

Two things stand out. At the top of the scale each question costs a lot: dropping from 54 to 52 in Reading and Writing loses 30 points, and from 44 to 42 in Math loses another 30. In the middle, a question is worth about 10 points. That is why a 1500-plus score needs near-perfect accuracy while moving from 1000 to 1100 only takes about ten more correct answers across the whole test.

SAT percentiles

Percentiles compare your total to a nationally representative sample of students. The mean total is close to 1030, and the top decile starts near 1350.

Reading and Writing vs Math

The two sections have different shapes. Reading and Writing has 54 questions, so each is worth slightly less on average, and its curve is nearly linear from 300 to 700. Math has 44 questions and a steeper top end: a single miss can cost 10 to 20 points above 700. Colleges receive both section scores and the total, and most superscore by combining your best section results across dates, so a weak section on one sitting is recoverable.

Estimates only. The College Board equates each SAT form and sets its own conversion; use a practice test's scoring guide for that test's exact table. Also see the ACT score calculator and the AP score calculator.
