How many questions can you miss on the SAT

There is no single number, and anyone who gives you one is guessing. For the adaptive digital SAT that you take in Bluebook, College Board publishes no raw-to-score conversion table at all, so the question has no answer by construction. For the eight paper practice tests that do have official tables, an answer exists but it is a range, and the tables disagree with each other by as much as 70 points at the same raw score.

Below is what the eight official tables actually say, measured directly from College Board’s published scoring guides for paper practice tests 4 through 11.

What the eight official tables say

The paper tests have 66 Reading and Writing questions and 54 Math questions. Each table gives a lower and an upper scaled score for every raw score. The columns below show the full envelope across all eight tests: the lowest lower bound and the highest upper bound anyone would get for that number of misses.

Questions missed	RW raw (of 66)	RW score across the 8 tables	Math raw (of 54)	Math score across the 8 tables
0	66	790-800	54	790-800
2	64	750-790	52	750-800
4	62	720-770	50	710-790
6	60	700-760	48	680-760
10	56	640-730	44	620-690
16	50	580-670	38	550-620
20	46	530-650	34	500-570
26	40	470-580	28	440-500
36	30	390-490	18	340-410

Read one row as a claim about uncertainty, not about your ability. Miss 20 Reading and Writing questions and the honest statement is that your section score sits somewhere between 530 and 650, and which end depends on a test form you did not choose.

Two separate things stack up to make that band so wide.

Reason one: every table gives a range, not a number

College Board prints this on page 3 of every paper scoring guide, verbatim: “Section and total scores for the paper version of this digital SAT practice test are expressed as ranges. That’s because the scoring method described in this guide is a simplified (and therefore slightly less precise) version of the one used in the actual test.”

The guides go on: “The ‘lower’ and ‘upper’ values associated with your raw score establish the range of scores you might expect to receive had this been an actual test.”

Across the eight SAT tables, the median gap between the lower and upper bound for a single raw score is 40 points per section. It narrows near 800, where the scale runs out of room, and it widens in the middle of the range where most students score.

Reason two: the tables disagree with each other

This is the part most sites skip. The same raw score does not mean the same thing on different practice tests, because the tests are not equally difficult and the tables correct for that.

Here is the lower bound for a Reading and Writing raw score of 40 (26 questions missed) on each of the eight official tables.

Practice test	Lower bound at RW raw 40
Test 4	530
Test 5	510
Test 6	540
Test 7	480
Test 8	490
Test 9	470
Test 10	470
Test 11	470

Same 40 correct answers, a 70-point spread. In Math the same effect is smaller but still real: at a raw score of 48, the lower bound runs from 680 to 730 across the eight tables. Our raw score conversion reference shows the full tables side by side if you want to check any other raw score yourself.

Why the adaptive test cannot be answered at all

The paper tables are a simplified stand-in. The test you actually sit works differently in three ways, each of which breaks the miss-counting question.

It is scored by Item Response Theory, not a lookup. College Board states that “the scores students receive are a product of several factors, characteristics of the questions they answered right or wrong (e.g., the questions’ difficulty levels), and the probability that the pattern of answers suggests they were guessing.” The SAT Suite Technical Manual puts the consequence plainly: two students may have the same number of correct answers but have different reported scale scores. The manual never uses the phrase “raw score” for the adaptive test.

It is adaptive within each section. Module 1 routes you to either a lower-difficulty or a higher-difficulty module 2. Missing 10 questions on a harder second module is not the same event as missing 10 on an easier one. College Board publishes no routing threshold, so no one can tell you how many correct answers in module 1 are needed to reach the harder route. Any specific number you see quoted for that is invented.

Eight of your 98 answers do not count. Each module contains exactly 2 pretest questions, so Reading and Writing has 50 scored questions and Math has 40. They are placed randomly and are indistinguishable from scored items. You could miss 8 questions and lose nothing, or miss 8 and lose all 8. There is no way to know which happened.

If you want a target, work backwards from the score

The useful version of this question is the reverse one: what raw score do I need. On the paper tables, these are the miss counts at which all eight tables still put your lower bound at or above the stated score.

Section score floor	Max misses in RW (of 66)	Max misses in Math (of 54)
750	2	2
700	6	5
650	9	8
600	14	12

Those are conservative by design. On a friendlier form you could miss more and land in the same place. Use the score needed calculator to work from a total target back to per-section requirements.

What to do with a practice test you just finished

If you took it in Bluebook, the app already gave you a score produced by the real scoring model. That number is better than anything a calculator can generate from a count of right answers, and feeding your Bluebook raw score into a paper table will give a badly wrong result. The Bluebook and paper scale problem explains why in detail.

If you took a paper version, use the table for that specific test rather than a generic chart. Our practice test score calculator holds all eight official SAT tables plus the PSAT ones and applies College Board’s own procedure: sum both module raw scores first, do one section lookup, then add the two lower bounds together and the two upper bounds together for the total range.

Then track your raw score across tests, not your converted score. Raw counts are directly comparable within a single test form and noisy across forms. If your Reading and Writing raw score moves from 44 to 52 over three practice tests, that is real progress, and it is more informative than watching a converted number bounce around inside a 70-point disagreement between tables.

Once you have a total you trust, the percentile calculator will tell you where it sits among test takers, which is usually the question underneath the miss-counting question in the first place.
