How many SAT questions can you miss and still get a 1500?

The short answer is roughly 5 to 8 questions total. But that number is less precise than it sounds, because the digital SAT uses Item Response Theory (IRT) and an adaptive format that make the final score depend not just on how many questions you miss but on which ones.

The approximate numbers

The digital SAT has 54 Reading and Writing questions and 44 Math questions, for 98 total. Each module includes about 2 experimental questions that are unscored, but they look identical to scored questions during the test.

Here are estimates for how many scored questions you can miss at various score levels. These are approximations because the exact conversion depends on the difficulty of the questions you miss and which second module you're routed to.

Target score	Approximate misses (Reading and Writing)	Approximate misses (Math)
1500+	3 to 5	2 to 4
1400+	7 to 10	5 to 7
1300+	12 to 15	8 to 11
1200+	17 to 20	12 to 15

At the 1500 level, you need around 95% accuracy across both sections. At 1400, around 88%. The margin for error gets tighter as the target score goes up.

Why there isn't a fixed answer

On the old paper SAT, there was a fixed conversion table for each test. You could count your mistakes and look up the scaled score. The digital SAT doesn't produce scores that way.

Your Module 1 performance determines what comes next. The test has two modules per section. Your performance on Module 1 determines whether you get a harder or easier Module 2. The harder Module 2 makes higher scores possible; the easier one caps your section score at around 600 to 650. To get the harder Module 2, you need to answer about two-thirds of Module 1 questions correctly. This routing is the single biggest factor in whether a high score is reachable on a given test. We've written about how the adaptive structure works in detail here.

IRT weights questions by difficulty. The SAT uses IRT to calculate scores, which means getting a hard question right contributes more to your score than getting an easy question right. Getting an easy question wrong hurts more than getting a hard question wrong. Two students who miss the same number of questions can end up with different scores depending on the difficulty of what they missed.

What this means for prep

Module 1 is the gatekeeper. Getting routed to the harder Module 2 is a prerequisite for scoring above around 1300 per section, and the cutoff is about two-thirds of Module 1 questions answered correctly. Every question in Module 1 matters because it affects which version of Module 2 you see. A student aiming for 1500 needs to be consistent in Module 1.

Don't spend too much time on the hardest questions. A common pattern is spending several minutes on a question that feels solvable, then having to rush through easier questions at the end of the module. Since easy questions you miss cost more under IRT than hard questions you miss, this trade-off usually hurts the score. If a question is taking too long, mark it for review and move on.

Going from 1400 to 1500 is harder than going from 1200 to 1300. The jump from 1400 to 1500 means eliminating about 5 to 7 additional errors, and those errors tend to be on the hardest questions, where improvement takes the most targeted effort. This is why students often plateau in the 1400s. We've written about what to do when scores plateau here.

Sharp is built for this kind of targeted work. It has a large bank of expert-written hard questions beyond what's available from the College Board, identifies the specific question types where you're losing points, and focuses practice there.
