- Format and timing

  **[How long is the SAT?](https://1600.now/sat-faq/how-long-is-the-sat)**

  The standard digital SAT has 134 minutes of testing and a 10-minute break: 2 hours 24 minutes once testing begins. Arrival, check-in, and instructions add time; approved accommodations or a School Day essay can change the schedule.
- Format and timing

  **[Can you bring a calculator to the SAT?](https://1600.now/sat-faq/can-you-bring-a-calculator-to-the-sat)**

  Yes. You may bring an approved non-CAS handheld calculator for Math, or use Bluebook’s embedded Desmos scientific or graphing calculator. Calculator use is allowed throughout Math, but not during Reading and Writing.
- Format and timing

  **[How many questions are on the SAT?](https://1600.now/sat-faq/how-many-questions-are-on-the-sat)**

  The standard digital SAT presents 98 questions: 54 Reading and Writing and 44 Math. Each of the four modules includes two unscored pretest questions, leaving 90 scored questions across the test.
- Scores and interpretation

  **[What is a perfect SAT score?](https://1600.now/sat-faq/what-is-a-perfect-sat-score)**

  A perfect SAT total is 1600: 800 in Reading and Writing plus 800 in Math. The total is a scaled score, so it is not a public count of how many questions you answered correctly.
- Scores and interpretation

  **[Is the SAT curved?](https://1600.now/sat-faq/is-the-sat-curved)**

  The SAT is not graded on a classroom-style curve against the people testing that day. College Board uses statistical scoring and equating to put different test forms on a comparable scale.
- Format and timing

  **[Does the SAT penalize guessing?](https://1600.now/sat-faq/does-the-sat-penalize-guessing)**

  No. The SAT has no deduction for a wrong answer. Make your best attempt on every question, and use an educated guess when you cannot solve it before the module ends.
- PSAT and National Merit

  **[PSAT vs SAT: What is the difference?](https://1600.now/sat-faq/psat-vs-sat)**

  The PSAT/NMSQT and SAT test related skills in the same standard digital timing: 2 hours 14 minutes plus a break. The PSAT/NMSQT tops out at 1520 and can qualify eligible students for National Merit; the SAT tops out at 1600 and is used in college admissions.
- Format and timing

  **[Is the SAT essay still required?](https://1600.now/sat-faq/is-the-sat-essay-required)**

  The weekend SAT has no essay. A separate essay remains in certain state-provided SAT School Day administrations, so ask your school coordinator whether your school-day test includes it.
- Scores and interpretation

  **[How is the SAT scored?](https://1600.now/sat-faq/how-is-the-sat-scored)**

  SAT Reading and Writing and Math each receive a 200–800 score; adding them gives a 400–1600 total. Digital scoring uses responses across both modules and question characteristics, so a correct-answer count alone cannot determine the score.
- Scores and interpretation

  **[What is an SAT percentile?](https://1600.now/sat-faq/what-is-a-sat-percentile)**

  An SAT percentile compares your score with a defined group. A 90th percentile means 90% of that group scored at or below your score; it does not mean you answered 90% of the questions correctly.
- Registration and policies

  **[When are the SAT test dates in 2026?](https://1600.now/sat-faq/when-are-the-sat-test-dates-2026)**

  In the current 2026–2027 testing cycle, the next SAT as of October 5, 2026 is November 7, 2026: register by October 23, or by October 27 with the late fee.

The August 22, September 12, and October 3 tests have already been held; September 12 scores were released September 25, 2026.
- Registration and policies

  Sign in to My SAT, open the specific registration, and choose Cancel Registration. Cancel by 11:59 p.m. Eastern Time on the Thursday before testing to receive the registration-fee refund, less the applicable $34 regular or $44 late cancellation fee. After that Thursday, the registration fee is not refunded.

  **[Is the SAT required for college in 2026?](https://1600.now/sat-faq/is-sat-required-for-college-2026)**

  There is no single US college testing rule. Some colleges require SAT or ACT scores, some make them optional, and others do not consider them for admission. Check the institution’s policy for your entry year and applicant category.
- Registration and policies

  **[Who is eligible for an SAT fee waiver?](https://1600.now/sat-faq/sat-fee-waiver-eligibility)**

  SAT fee waivers are for eligible low-income 11th- and 12th-grade students in the US or US territories, and eligible US citizens living abroad. Qualifying benefits include two SAT registrations and unlimited score reports.
- Scores and interpretation

  **[How long are SAT scores valid?](https://1600.now/sat-faq/how-long-are-sat-scores-valid)**

  SAT scores do not have one universal college-admission expiration date. Colleges decide whether to accept older scores. College Board archives scores after you leave high school and go a year without testing; archiving does not automatically make them unusable.
- Format and timing

  **[Can you use scratch paper on the SAT?](https://1600.now/sat-faq/can-you-use-scratch-paper-on-the-digital-sat)**

  Yes. Testing staff provide scratch paper for both Reading and Writing and Math. You may not bring your own paper; ask the proctor if you need more, and leave all scratch paper with testing staff afterward.
- Format and timing

  **[What happens if you run out of time on the SAT?](https://1600.now/sat-faq/what-happens-if-you-run-out-of-time-on-sat)**

  When a digital SAT module’s timer ends, you lose access to that module and continue according to the test sequence. Blank answers do not earn credit, and there is no wrong-answer deduction, so make a best attempt before time expires.
- PSAT and National Merit

  **[Is the SAT harder than the PSAT?](https://1600.now/sat-faq/sat-vs-psat-difficulty)**

  The SAT assesses a broader difficulty range than the PSAT/NMSQT and has a higher score ceiling: 1600 instead of 1520. They test related skills, but a PSAT result does not guarantee any fixed increase on the SAT.
- PSAT and National Merit

  **[What PSAT score qualifies for National Merit?](https://1600.now/sat-faq/what-psat-score-qualifies-for-national-merit)**

  National Merit screening uses your PSAT/NMSQT Selection Index, not one nationwide total-score cutoff. Semifinalist qualifying scores vary by state or selection unit and graduation class; eligibility requirements and later application steps also matter.
- PSAT and National Merit

  **[How is the National Merit Selection Index calculated?](https://1600.now/sat-faq/how-is-the-national-merit-selection-index-calculated)**

  Double your PSAT/NMSQT Reading and Writing score, add Math, then divide by 10. The Selection Index ranges from 48 to 228 because each PSAT/NMSQT section ranges from 160 to 760.
