How the digital SAT works, how the adaptive modules decide your score, and how to study.

Watch M0-1 to M0-3, then take Practice Test 1 as your diagnostic. Its results tell you which question types to fix first. M0-4 sets up the error log, and M0-5 covers answer-choice tactics for every section.

  1. M0-1How the digital SAT works

    You score higher when nothing about the format surprises you. Students who learn the structure first spend their test minutes on questions, not on figuring out the screen.

    • How the digital SAT works6m
  2. M0-2Scores, targets and how the adaptive modules decide your score

    Your score depends on more than how many questions you get right. It also depends on which second module you are given, and that is decided by your first. The harder Module 2 is what makes the top of the score range reachable.

    6m1 video

    • Scores, targets and how the adaptive modules decide your score6m
  3. M0-3Your study plan: diagnose, learn, check, review

    Most students study by taking test after test. A better plan is to fix one question type at a time: find the type you miss most, learn it, redo your misses until you can explain them, and only then move on.

    5m1 video

    • Your study plan: diagnose, learn, check, review5m
  4. M0-4The error log: turning every miss into points

    Most students do practice sets, check the score, and move on. The misses are where the points are, because each one points to a skill you can fix. Without a record, you repeat the same mistakes on test day.

    5m1 video

    • The error log: turning every miss into points5m
  5. M0-5Answer-choice tactics: eliminate, plug in, work backward

    Every multiple-choice question hands you four options, and one of them is right. When the direct route is slow or you are stuck, the options themselves can lead you to the answer, as long as you use them with a plan instead of guessing.

Reading and Writing

16 lessons16 videos2h 3m

One method for each question type, from Words in Context and evidence to boundaries, transitions and the notes questions.

Start with RW-01. Lessons 2 to 9 cover the reading questions, from Words in Context to literature and poetry. Lessons 10 to 15 cover boundaries, form, transitions and rhetorical synthesis. RW-16 builds the vocabulary behind them.

  1. RW-01How to read a short SAT passage

    Every Reading and Writing question comes with its own short passage, and most wrong answers come from reading it too fast or too loosely. A careless read costs you the point and the time you spend rereading.

    7m1 video

    • How to read a short SAT passage7m
  2. RW-02Words in Context: the precise word

    These questions ask you to fill a blank or define a word as it is used in the passage. They look easy because every option is a real word, which is exactly why students miss them: the most familiar meaning of the word is often the wrong one.

    7m1 video

    • Words in Context: the precise word7m
  3. RW-03Text Structure and Purpose

    These questions ask what a passage or one sentence in it is doing, not what it says. The options are all built from true-sounding verbs, so students who read for content alone get pulled toward the wrong one.

    7m1 video

    • Text Structure and Purpose7m
  4. RW-04Cross-Text Connections

    You get two short texts and a question about how the author of one would respond to a claim in the other. These questions reward a tight, two-step read, and they punish students who blend the two texts into one idea.

    8m1 video

    • Cross-Text Connections8m
  5. RW-05Central Ideas and Details

    You get a short passage and a question like "Which choice best states the main idea of the text?" or "According to the text, what was true of...?" Every wrong option is built from real words in the passage, so skimming and picking the option that sounds familiar costs you points.

    7m1 video

    • Central Ideas and Details7m
  6. RW-06Command of Evidence: quotations and findings

    These questions give you a claim and ask which quotation illustrates it, or which finding would support or weaken it. The wrong options are on topic, so an answer that only sounds related costs you the point.

    8m1 video

    • Command of Evidence: quotations and findings8m
  7. RW-07Command of Evidence: tables and graphs

    A short passage makes a claim, a table or graph sits beside it, and the question asks which choice uses the data to complete the text. Most wrong options quote numbers correctly but support a different point, so reading the graph alone does not earn the point.

    8m1 video

    • Command of Evidence: tables and graphs8m
  8. RW-08Inferences: completing the logic

    You get a short passage that ends in a blank, and the question is "Which choice most logically completes the text?" Several options sound smart, but only one follows from what the passage has already set up.

    8m1 video

    • Inferences: completing the logic8m
  9. RW-09Reading literature and poetry on the SAT

    Some Reading and Writing questions give you a short excerpt from a novel, play or poem, with old-fashioned sentences, dialogue and irony. Students lose points here by choosing an answer that sounds right for the whole book instead of one that the lines on the screen actually support.

    8m1 video

    • Reading literature and poetry on the SAT8m
  10. RW-10Boundaries 1: joining and separating sentences

    Boundaries questions give you a sentence with a blank and four punctuation choices. They are among the most predictable questions on the test, and a single idea decides most of them: can the words on each side of the blank stand alone as a sentence?

    8m1 video

    • Boundaries 1: joining and separating sentences8m
  11. RW-11Boundaries 2: commas, dashes, colons and supplements

    The other half of Boundaries tests punctuation inside a sentence: where commas, dashes and colons belong, and where no mark belongs at all. Students lose points by adding punctuation that sounds like a pause but splits words that must stay together.

    8m1 video

    • Boundaries 2: commas, dashes, colons and supplements8m
  12. RW-12Form 1: subject-verb agreement and verb forms

    These questions give you a blank and four versions of one verb, such as suggest, suggests, has suggested and is suggesting. The test hides the real subject behind extra words, so choosing the verb that sounds right usually fails.

    7m1 video

    • Form 1: subject-verb agreement and verb forms7m
  13. RW-13Form 2: pronouns, possessives and modifiers

    These questions give you a sentence with a blank and four choices that look almost alike: its or it's, researcher's or researchers', or a sentence opening that has to match the subject after the comma. They cost points because every choice sounds fine when you read it fast.

    8m1 video

    • Form 2: pronouns, possessives and modifiers8m
  14. RW-14Transitions

    A transition question gives a short passage with one blank at the start of a sentence and four linking words such as However, For example or Consequently. They cost points when you choose a word that sounds smart instead of the one that fits how the two ideas relate.

    7m1 video

    • Transitions7m
  15. RW-15Rhetorical Synthesis: using the notes

    You get a bulleted list of notes and a goal such as summarize the theory or explain how the decision affected audiences, then four sentences built from those notes. They cost points because all four use true facts, and only one does the job the goal asks for.

    7m1 video

    • Rhetorical Synthesis: using the notes7m
  16. RW-16Vocabulary that shows up and how to learn it fast

    Words in Context questions, and the passages and answer choices around them, use words that strong readers know but rarely say out loud. You lose points two ways: you meet a word you do not know, or you know a word's everyday meaning and miss the one the sentence uses.

Math

Desmos and grid-in answers first, then algebra, quadratics and exponentials, percentages and data, geometry and trigonometry.

Start with M-01 on Desmos and M-02 on entering grid-in answers. After that, open the lessons your diagnostic points to, or work through them in order. M-22 collects the formulas and facts to know cold.

  1. M-01Desmos: the calculator that solves for you

    Some Math questions ask where two graphs meet, which value makes an equation true, or which constant makes a system behave a certain way. The built-in graphing calculator answers these in under a minute, and a miss costs the same points as any other question.

    8m1 video

    • Desmos: the calculator that solves for you8m
  2. M-02Grid-in questions: entering answers that count

    About a quarter of Math questions are student-produced responses: there are no choices, and you type the answer. They cost points when the math is right but the answer is not in a form you can enter, or when you skip the question because there is nothing to guess from.

    7m1 video

    • Grid-in questions: entering answers that count7m
  3. M-03Linear equations in one variable

    These questions give you one equation, or a short story that turns into one, and ask for the value of x or for a constant that changes how many solutions it has. They are some of the most reliable points on the test, and careless sign errors are what lose them.

    7m1 video

    • Linear equations in one variable7m
  4. M-04Linear equations in two variables

    These questions give a line as an equation, a table or a story, and ask for a slope, an intercept, a missing point or the equation itself. The forms of a line trip people up, so knowing how to read each one quickly pays off.

    7m1 video

    • Linear equations in two variables7m
  5. M-05Linear functions: slope, intercept and meaning

    These questions give a function in function notation and ask you to evaluate it, shift it, invert it, or say what its slope and intercept mean in a story. The notation looks harder than the math.

    7m1 video

    • Linear functions: slope, intercept and meaning7m
  6. M-06Systems of linear equations

    Each system question gives two equations, often as a story, and asks for x, y, or a constant that changes the number of solutions. Mistakes come from reporting the wrong variable or from setting up the story incorrectly.

    7m1 video

    • Systems of linear equations7m
  7. M-07Linear inequalities

    You will see an inequality to solve, a word problem built on "at most" or "at least", or a system where you must find the largest or smallest allowed value. One flipped sign or one skipped unit conversion turns an easy question into a miss.

    8m1 video

    • Linear inequalities8m
  8. M-08Equivalent expressions

    The question gives you an expression and asks which option equals it, or asks for one coefficient after you expand or rewrite. Every wrong option comes from a real algebra slip, so a careless sign or product is a lost point.

    8m1 video

    • Equivalent expressions8m
  9. M-09Quadratics: factoring, vertex and roots

    Quadratics show up as equations to solve, as a parabola's vertex or zero in a word problem, and as equations with a square root or a fraction that secretly become quadratics. The harder ones reward a quick structural insight.

    7m1 video

    • Quadratics: factoring, vertex and roots7m
  10. M-10Exponential functions and growth

    These questions give a function like f(x) = a · bˣ, a graph, or a growth story, and ask for a rate, a later value, or when exponential growth passes linear growth. Percent-change versions look trickier than they are, and they cost points when you read the wrong time step.

    7m1 video

    • Exponential functions and growth7m
  11. M-11Nonlinear equations and systems

    You will see a line and a parabola, two curves, or an equation with a square root, and be asked for an intersection, a constant that gives exactly one solution, or an extraneous answer. Substitution is the engine, and the trap is leaving answers unchecked.

    8m1 video

    • Nonlinear equations and systems8m
  12. M-12Ratios, rates, proportions and units

    Ratio and rate questions hide inside word problems about paint mixes, machines, speeds and map scales. They look friendly, so students rush, and one flipped ratio or skipped unit conversion turns a one-minute question into a lost point.

    7m1 video

    • Ratios, rates, proportions and units7m
  13. M-13Percentages

    Percent questions ask for a part, a whole or a change, often in two steps and often with a base that is not the number you see first. The test sets traps on which number the percent is taken of, and a wrong base costs the point every time.

    8m1 video

    • Percentages8m
  14. M-14One-variable data: center and spread

    These questions hand you a list, a dot plot, a histogram or a frequency table and ask for a mean, median, range or standard deviation, or ask what happens to them when a value is added, removed or shifted. Many look like heavy arithmetic, and most are not.

    7m1 video

    • One-variable data: center and spread7m
  15. M-15Two-variable data and scatterplots

    You are given a scatterplot or the equation of a line of best fit and asked to predict a value, interpret the slope, find a residual or choose between a linear and an exponential model. The arithmetic is short, so the points are lost on the setup.

    8m1 video

    • Two-variable data and scatterplots8m
  16. M-16Probability and conditional probability

    Probability questions give counts in a table, a plot or a sentence and ask for a fraction. The ones that cost points are conditional: the wording shrinks the group first, and a student who divides by the grand total picks a tempting wrong answer.

    7m1 video

    • Probability and conditional probability7m
  17. M-17Samples, margin of error and study design

    These questions hand you a survey or an experiment and ask what you can fairly conclude, or what a sample says about a whole population. They are short, but one wrong word in your reasoning, like "caused" or "all adults", turns a right idea into a wrong answer.

    8m1 video

    • Samples, margin of error and study design8m
  18. M-18Area and volume

    These questions give you a prism, cylinder, cone or composite solid and ask for a surface area, a volume or a missing length. The formulas are not the hard part. The points go to students who find the right radius or height first, and who do not grab a near-miss formula.

    8m1 video

    • Area and volume8m
  19. M-19Lines, angles and triangles

    A figure with a few labeled angles or sides, and a missing value to find. These are among the quickest Math questions to get right and the easiest to lose by grabbing the wrong angle relationship.

    7m1 video

    • Lines, angles and triangles7m
  20. M-20Right triangles and trigonometry

    A right triangle hides in the problem, sometimes in a picture and sometimes in a story about a ladder, cable or ramp. You are asked for a side, or for a sine, cosine or tangent. Missing the right triangle costs the whole question.

    8m1 video

    • Right triangles and trigonometry8m
  21. M-21Circles

    Circle questions come in two kinds: geometry (angles, arcs, tangent lines, sectors) and algebra (the equation of a circle in the xy-plane). Both are formula-and-fact problems, so a small toolbox gets you most of the points.

    7m1 video

    • Circles7m
  22. M-22Formulas and facts to know cold

    The reference sheet does not replace knowing your formulas cold. A question on slope, a vertex, a circle or a percent change expects the formula from memory, and looking for it costs time you do not have.

    9m1 video

    • Formulas and facts to know cold9m
  23. M-23Functions: notation, composition and transformations

    Function questions hand you f as a rule, a table or a graph, then ask for f(a), f(g(x)), or the zero of a shifted function like g(x) = f(x - 15). The algebra is light; points are lost by reading the notation the wrong way, especially by shifting in the wrong direction.

    7m1 video

    • Functions: notation, composition and transformations7m
  24. M-24Polynomials, rational equations, radicals and absolute value

    These questions look like four different topics: a cubic's zeros, an equation with x in a denominator, a square root equation, and an absolute value equation. Each one has a short standard method, and each has one classic way to lose the point: a missed case, or an answer that does not work in the original equation.

    8m1 video

    • Polynomials, rational equations, radicals and absolute value8m
  25. M-25Exponent and radical rules

    Exponent questions ask which expression is equivalent to a messy product of powers and roots, or give "equivalent to xᵏ" and ask for k. Every option looks plausible, and one slip, like multiplying exponents that should be added, lands you on a planted wrong answer.

    7m1 video

    • Exponent and radical rules7m
  26. M-26Radians, the unit circle and arc length

    Circle questions give a central angle, sometimes in degrees and sometimes in radians, and ask for an arc length, a sector area, or a sine or cosine value. Students who know the formulas still lose points by mixing degrees with radians, or by using the full circumference when the question wants a fraction of it.

The hardest Reading and Writing and Math patterns, each named before it is solved.

Open an Advanced lesson once its core question type is solid. X-RW1 to X-RW6 cover Reading and Writing and X-M1 to X-M6 cover Math. The 16 timed Hard Module Drills follow this module.

  1. X-RW1Hard Words in Context: second meanings and exact tone

    On the hardest Words in Context questions, every option is a real word that could fit a sentence like this one, and three of them fit a different sentence. These questions decide whether the harder Module 2 gives you the points at the top of the score range.

    8m1 video

    • Hard Words in Context: second meanings and exact tone8m
  2. X-RW2Hard inferences and evidence: scope, qualifiers and what the text can support

    Hard inference and evidence questions give you a short passage with a claim, and four options that all sound scientific. The point goes to the option that fits the claim exactly, and the wrong ones are built to be almost right.

    8m1 video

    • Hard inferences and evidence: scope, qualifiers and what the text can support8m
  3. X-RW3Hard boundaries and form: long subjects, supplements and colons

    On the hardest grammar questions the rule is easy, but the sentence is long and the blank sits far from the words it depends on. Strong students lose these points by trusting what sounds right, because the nearest noun is often not the one that matters.

    8m1 video

    • Hard boundaries and form: long subjects, supplements and colons8m
  4. X-RW4Hard transitions and synthesis: the exact relationship and the exact goal

    On the hardest transition questions the sentences are long and abstract, so the link between them is easy to misjudge. On the hardest synthesis questions all four options use true facts from the notes, and three of them do the wrong job.

    8m1 video

    • Hard transitions and synthesis: the exact relationship and the exact goal8m
  5. X-RW5Hard structure, purpose and paired texts

    The hardest structure and purpose questions describe a passage in abstract words, and every option sounds scholarly. The hardest paired-text questions ask how one author would answer the other, and the options put true statements in the wrong mouth.

    9m1 video

    • Hard structure, purpose and paired texts9m
  6. X-RW6Hard data questions in Reading and Writing

    You get a short text that makes a claim and a bar chart, line graph or table. Four options each quote the figure correctly or incorrectly, and you must pick the one that supports the exact claim. On the hardest questions at least two options are true of the data.

    8m1 video

    • Hard data questions in Reading and Writing8m
  7. X-M1Parameters: no solution, infinitely many and the value of k

    A constant like k sits inside an equation or system, and the question tells you how many solutions there are. These items look short, but one skipped step in the algebra points you to a tempting wrong value of k.

    8m1 video

    • Parameters: no solution, infinitely many and the value of k8m
  8. X-M2Advanced quadratics: discriminant, vertex form and intersections

    The hardest quadratic questions on the test do not ask you to factor. They ask where a parabola meets a line, how a vertex controls a maximum, or what a constant must be for a graph to touch something once. One wrong setup costs the point.

    8m1 video

    • Advanced quadratics: discriminant, vertex form and intersections8m
  9. X-M3Hard modeling: exponential, linear and what the numbers mean

    Hard modeling questions give you a real situation and ask for a rate, a percent, or the meaning of a number. The algebra is short, so most points are lost by answering a slightly different question than the one asked.

    8m1 video

    • Hard modeling: exponential, linear and what the numbers mean8m
  10. X-M4Hard algebra: rational, radical and equivalent forms

    On the hardest equivalent-expression questions, the algebra is only half the job: a constant hides in a graph or table, or the answer must be in one specific form. One slip in a sign or a form choice and every wrong option looks right.

    8m1 video

    • Hard algebra: rational, radical and equivalent forms8m
  11. X-M5Hard geometry: circles, similar triangles and trigonometry

    The hardest geometry questions give you a figure with only a few numbers and no obvious path. Points are lost by missing a hidden right angle, or by finding one answer when the figure allows two.

    8m1 video

    • Hard geometry: circles, similar triangles and trigonometry8m
  12. X-M6Hard inequalities and systems in context

    The hardest questions here ask for a maximum, a minimum or a constant that makes a system degenerate. There is no equation to solve in the usual way, so students who just 'solve for x' get stuck or round the wrong direction.

Every option explained

Every wrong answer has a reason

Each question explains the right answer step by step, then names the exact slip behind every other option, so a miss teaches you something.

Reading and WritingWords in Context
In 2009, microbiologist Frank Reith and his colleagues investigated how the bacterium Cupriavidus metallidurans manages to survive in environmental soils heavily contaminated with toxic heavy metals. The researchers observed that when the bacteria ingest dissolved, highly reactive gold ions, they deploy specialized cellular enzymes to force the ions out of solution, precipitating them as solid gold nanoparticles on the bacterial surface. Because these solid nanoparticles are chemically inactive and therefore completely harmless to the cell, this enzymatic precipitation process effectively allows the bacteria to ______ the severe biological threat posed by the dissolved metal.

Which choice completes the text with the most logical and precise word or phrase?

Why A is right

  1. 1The word "neutralize" means to render something ineffective or harmless.
  2. 2The passage states that the dissolved gold ions are a "severe biological threat," but the bacteria convert them into solid nanoparticles that are "completely harmless."
  3. 3Therefore, the bacteria neutralize the threat.

Frequently asked questions

Everything you need to know about SAT prep.

About SAT prep

The digital SAT has two sections, Reading and Writing, and Math, and each section has two modules. Reading and Writing has 54 questions in 64 minutes: two modules of 27 questions, each 32 minutes long. Math has 44 questions in 70 minutes: two modules of 22 questions, each 35 minutes long. The test takes 2 hours and 14 minutes in total, with a 10-minute break between the sections.

How you do on the first module of a section decides whether your second module is easier or harder. The harder second module is what makes the top of the score range reachable, so accuracy in Module 1 matters most. SAT Explained has a lesson on exactly this, and the 10 practice tests adapt the same way.

Each section is scored from 200 to 800, so the total runs from 400 to 1600. There is no penalty for a wrong answer, so never leave a question blank.

61 video lessons (7.6 hours) in five modules: Start Here, Reading and Writing, Math, Advanced (the 700+ questions) and Test Day. Alongside the lessons: 4,000+ practice questions with every answer option explained, 10 full-length adaptive practice tests of 98 questions each scored 400 to 1600, 16 timed Hard Module Drills, 105 lesson quizzes and 600+ flashcards.

Watch the first three Start Here lessons, then take Practice Test 1 as your diagnostic. It scores each section and shows which question types to fix first. The error log lesson then shows you how to turn every miss into a rule you keep.

Yes. A built-in graphing calculator (Desmos) is available for all of Math, and a reference sheet of formulas is provided. SAT Explained opens Math with a lesson on the calculator, and the math lessons show a graphing calculator route wherever one exists.

Know your pace: about 71 seconds a question in Reading and Writing and about 95 in Math. Time left over in one module does not carry over to the next, and once a module ends you cannot go back to it. The Test Day module turns those facts into a plan for all four modules.

Some questions in each module are unscored pretest questions. You cannot tell which ones they are, so treat every question as scored.

Upload an official SAT score from the 90 days before you buy, complete the plan (at least 90% of your assigned QBank questions and every full-length practice test in it), then take the official SAT within 60 days of your access ending. If your total score rose by fewer than 100 points, we extend your access free for the same length you bought. It is extra study time, not a cash refund.

Practice Test 1 gives a starting score for each section, and every full-length practice test returns a total from 400 to 1600 with a score for each section, so you can compare where your student began with where they are now.

Check the requirements of the colleges you apply to. PrepSolution has a complete course for each test, built the same way, so your student can prepare for whichever one they choose.
