Khan Academy offers the most comprehensive free Digital SAT preparation available anywhere, built through an official partnership with the College Board. The Khan Academy Digital SAT programme provides access to full-length adaptive practice tests, thousands of official practice questions, skill-focused drills, video lessons, and personalised study recommendations — all at no cost to the student. For the vast majority of test-takers, Khan Academy combined with the College Board Bluebook app provides everything needed to prepare for the Digital SAT without purchasing expensive commercial prep materials.

The Official Digital SAT Prep on Khan Academy is available at khanacademy.org/digital-sat. After creating a free account, students complete a brief diagnostic assessment that identifies their current skill level in both Reading and Writing and Math. Khan Academy then generates a personalised practice plan that directs students to the specific skills where they have the most room to improve. This targeted approach is significantly more efficient than reviewing material uniformly across all topics, particularly for students preparing within a limited timeframe.

The Digital SAT replaced the paper SAT in the United States beginning in March 2024 for domestic test-takers, following an earlier international rollout in 2023. The digital format uses a computer-adaptive testing (CAT) structure in which each section consists of two modules.

Performance on the first module determines the difficulty level of the second module — students who perform well on the first module receive a harder second module, while those who struggle receive an easier second module. This adaptive structure means that the Digital SAT can measure a wide range of ability levels with fewer questions than the previous paper format, reducing total testing time by roughly an hour compared to the old SAT.

Reading and Writing on the Digital SAT contains 54 scored questions plus 10 unscored questions, spread across two modules of 27 questions each. All Reading and Writing questions are passage-based — each question is accompanied by a short reading passage of one to three paragraphs. The passages are drawn from four content domains: literature, history and social studies, science, and humanities. Questions assess information and ideas (comprehension, inferences, central ideas), craft and structure (vocabulary in context, text structure, author purpose), expression of ideas (revision, sentence combining, transitions), and standard English conventions (grammar, punctuation, sentence boundaries).

The Math section contains 44 scored questions across two modules of 22 questions each. Approximately 75% of Math questions are four-option multiple choice, and 25% are student-produced response questions where students enter their own answer rather than selecting from choices. A scientific calculator (or the built-in Desmos graphing calculator) is permitted throughout the entire Math section.

The four Math content domains are: algebra (linear equations, systems of equations, linear functions); advanced math (quadratic and exponential functions, equivalent expressions); problem-solving and data analysis (ratios, percentages, probability, data interpretation); and geometry and trigonometry. A reference sheet with commonly used formulas is available throughout the test.

The Digital SAT scoring scale ranges from 400 to 1600, with two section scores of 200-800 each. Unlike the paper SAT, the Digital SAT does not report subscores or cross-test scores; the section scores and total score are the primary reported values.

Colleges and universities evaluate Digital SAT scores using the same scale they used for paper SAT scores, and concordance tables allow comparison between old SAT scores and Digital SAT scores for admissions purposes. Students who earned paper SAT scores and are retaking the test in the digital format can use the College Board score comparison tool to understand how their old score corresponds to the new scale.

The digital sat score calculator provided by Khan Academy and College Board allows students to estimate their score based on practice test performance. After completing a full-length practice test in the Bluebook app, the score calculator converts the number of correct answers to a scaled score using an equating process similar to the actual exam.

Practice test scaled scores provide the most accurate prediction of actual exam performance. Khan Academy skill practice scores, while useful for identifying weak areas, should not be used to estimate final exam scores since skill practice questions are presented outside the adaptive module structure of the actual test.

How long is the Digital SAT? The Reading and Writing section takes 64 minutes across two modules of 32 minutes each, with a one-minute break between modules. The Math section takes 70 minutes across two modules of 35 minutes each, with a one-minute break between modules. There is a 10-minute break between the Reading and Writing section and the Math section.

Total seated time, including the 10-minute break, module breaks, and a brief survey at the end, is approximately 2 hours and 24 minutes for most test-takers. Students who qualify for extended time accommodations have their time extended by the same factor approved by College Board.

Students who want to maximise their Digital SAT score improvement per hour of study should consider the following principle: improving from 1100 to 1200 is typically easier than improving from 1300 to 1400, and improving from 1400 to 1500 requires significantly more targeted work at the most difficult question types.

Khan Academy's personalised plan automatically adjusts for this curve — it prioritises the skill gaps with the highest potential score impact rather than trying to achieve mastery at the hardest level in every domain simultaneously. Students near the top of the score range should supplement Khan Academy with detailed review of the hardest question types and extended time on the most challenging practice test questions.

The Reading and Writing section of the Digital SAT rewards active, close reading habits more than vocabulary memorisation. Each short passage contains specific evidence that supports the correct answer to each question; there is always a textually defensible reason why one answer is correct and the other three are wrong.

Building the habit of identifying this textual evidence — rather than relying on general impressions or outside knowledge — is the fundamental skill that Reading and Writing preparation should develop. Khan Academy Reading and Writing practice questions always include explanations that identify the specific textual evidence supporting the correct answer, making them an excellent tool for building this habit systematically.

Students aiming for highly selective colleges should target scores above 1400, which typically requires strong performance in both sections and thorough preparation across all skill categories. For students applying to schools where the average enrolled student scores around 1200-1350, focus preparation on reaching and exceeding that target range through consistent Khan Academy practice and full-length Bluebook test review.

The most effective way to use Khan Academy for Digital SAT preparation is to begin with the full diagnostic and personalised practice plan rather than jumping directly into topic-specific drills. The diagnostic accurately identifies your starting skill level in both Reading and Writing and Math within approximately 20-30 minutes, and the resulting study plan prioritises the topics where improvement will have the greatest impact on your score. Students who skip the diagnostic and dive directly into random practice miss the efficiency benefit of targeted, personalised preparation.

Khan Academy's Digital SAT prep is organised around 19 skill areas in Reading and Writing and 22 skill areas in Math. Each skill area contains short quizzes of 4-6 questions that provide immediate feedback on correct answers. As you complete skill practice, Khan Academy tracks your performance and updates its recommendations dynamically. Students who practice consistently — even 20-30 minutes per day for 8-12 weeks — see meaningful score improvements as demonstrated in College Board research showing an average 115-point combined score increase for students who completed 20+ hours of Khan Academy practice.

Full-length practice tests are the single most important component of Digital SAT preparation beyond Khan Academy skill practice. The College Board Bluebook app (available free on Mac, Windows, iPad, and Chromebook) contains four official full-length Digital SAT practice tests that closely mirror the actual exam experience, including the adaptive module structure. These tests produce scaled scores comparable to actual exam scores and provide the most reliable measure of exam readiness. Students should complete at least two full practice tests before their exam date, ideally under realistic timed conditions without interruptions.

The Khan Academy lesson videos are particularly valuable for understanding the concepts behind Digital SAT Math questions. The videos cover every major topic tested on the exam — from linear equations and functions to quadratic equations, geometry, and data interpretation — with clear explanations of the underlying concepts and worked examples of exam-style problems. Students who struggle with a particular skill category should watch the corresponding Khan Academy videos before attempting more skill practice questions, as understanding the concept before practising is more efficient than attempting to infer the concept from incorrect answers alone.

Vocabulary in context is a significant component of the Digital SAT Reading and Writing section and a topic that rewards consistent practice over an extended period. Rather than memorising lists of obscure words, the most effective vocabulary preparation for the Digital SAT involves reading widely in different genres and domains — literary fiction, scientific articles, historical essays — while paying attention to how words function in different sentence contexts.

Khan Academy vocabulary practice presents words in passage context, making it more representative of the actual test than isolated flashcard study. A regular reading habit of 20-30 minutes per day over several months produces vocabulary improvements that are durable and transfer well to the actual exam.

The digital sat formula sheet provided during the exam includes approximately 12 geometric and trigonometric formulas: area formulas for triangles, circles, rectangles, and other shapes; the Pythagorean theorem; special right triangle ratios; volume formulas for rectangular prisms, cylinders, spheres, cones, and pyramids; and basic trigonometric ratios. Students should not rely on the formula sheet as a crutch — knowing these formulas from memory allows you to work faster and focus cognitive resources on the problem-solving logic rather than looking up formulas. Practice using and applying each formula through Khan Academy geometry and trigonometry skill drills.

Adaptive test strategy is an important but often misunderstood aspect of Digital SAT preparation. Because the difficulty of Module 2 depends on Module 1 performance, some students wonder whether they should intentionally underperform on Module 1 to receive an easier Module 2. This strategy is strongly counterproductive — the easier Module 2 has a lower ceiling score, meaning even a perfect Module 2 cannot produce a top-tier section score.

The only viable strategy is to perform as well as possible on Module 1, which puts you in the high-difficulty pool for Module 2, where scoring well produces the highest possible section scores. Preparing thoroughly and trusting your skills on Module 1 is the correct adaptive strategy.

Students who have taken the paper SAT previously and are preparing for the Digital SAT will find that the overall content — reading comprehension, grammar, algebra, and higher math — is similar, but the shorter passages on the Digital SAT and the individual-passage-per-question format represent a significant structural change.

Paper SAT Reading passages were long and shared across multiple questions; Digital SAT passages are short, often just 1-3 paragraphs, and each passage accompanies only one question. Students transitioning from paper to digital preparation should prioritise practising with Digital SAT format materials rather than using leftover paper SAT prep books, whose passage formats are no longer representative.

Time management on the Digital SAT is less challenging than on the paper SAT for most students because the shorter passages and fewer questions per section reduce cognitive load. However, students who struggle with time should practise each module individually with a timer before attempting full tests.

The Reading and Writing modules require approximately 71 seconds per question; the Math modules allow approximately 95 seconds per question. Students who find themselves consistently running out of time should first ensure they are not spending too long on difficult questions — flagging and returning is always the better strategy than getting stuck on a single question at the expense of questions you could answer quickly.

After completing your Digital SAT preparation and taking the exam, your score report (available approximately two weeks after the test date through the College Board website) provides section scores, a total score, and a percentile rank showing how your score compares to other test-takers. Colleges consider Digital SAT scores as one component of holistic admissions review alongside GPA, course rigor, essays, recommendations, and extracurricular activities. Many colleges have adopted test-optional or test-flexible policies, so check the admissions policy of each school on your list to understand how SAT scores factor into their review process before deciding whether to submit scores.

Students who qualify for College Board accommodations — extended time, breaks, alternative testing environments — should apply through the College Board Services for Students with Disabilities (SSD) well before their planned test date. The application process takes time to review, and accommodations must be approved before you register for your exam date. Khan Academy Digital SAT practice is available without timing restrictions at any time, making it an accessible preparation tool regardless of testing accommodations status.

Khan Academy Digital SAT prep can be accessed on any device with internet connectivity — desktop, tablet, or smartphone — making it easy to practice during commutes, lunch breaks, or other short windows throughout the day. Consistent short practice sessions distributed over several weeks produce more durable learning than cramming in a few long sessions immediately before the exam.
