Getting to know the exam
BeginnerLearn the structure of the Digital SAT, its adaptive modules, scoring, registration, test day and a study plan.
- 1The Digital SAT: format, adaptive modules and scoringThe two sections and four modules of the Digital SAT in its 2026 format: timing, the adaptive design, the 400–1600 score scale and math questions where you type your own answer.15 min
- 2Registration, test day and a study planHow to register for the SAT, what to bring on test day, how to use Bluebook practice tests and a 10-week study plan.14 min
The Reading and Writing section
IntermediateMaster the four question areas on short passages — craft and structure, information and ideas, grammar and expression — with clear strategies.
- 3Craft and Structure: words, purpose and paired textsThe first question group in Reading and Writing: words in context, text purpose and structure, and connections between two texts — with strategies and original SAT-style practice.18 min
- 4Information and Ideas: central ideas, evidence and inferencesFinding the central idea, supporting a claim with text or table data and drawing a logical conclusion: strategies for SAT Information and Ideas questions.18 min
- 5Standard English Conventions: punctuation and grammarSAT grammar questions: punctuation between clauses (semicolon, colon, comma splices), subject–verb agreement, verb tense, pronouns and modifier errors.20 min
- 6Expression of Ideas: transitions and rhetorical synthesisThe two question types at the end of each module: transitions that show how sentences relate, and building a sentence from notes for a specific goal (rhetorical synthesis).16 min
Math: Algebra and Advanced Math
IntermediateLearn the linear, quadratic, exponential and rational topics behind about 70 percent of the Math questions.
- 7SAT Algebra: linear equations, functions and systemsAbout 35 percent of the Math questions: linear equations and inequalities, slope and its meaning in context, systems of two equations and the number of solutions.20 min
- 8Advanced Math I: quadratic and exponential functionsThe three forms of a quadratic, the discriminant, the sum and product of roots, the vertex; exponential growth and decay models and how to tell them from linear ones.22 min
- 9Advanced Math II: functions, polynomials, radicals and rational expressionsFunction notation and composition, graph transformations, polynomial zeros and the remainder theorem, rational exponents, and extraneous solutions in radical and rational equations.22 min
Math: data, geometry and Desmos
AdvancedPercentages, statistics, probability, geometry, trigonometry and smart use of the built-in Desmos calculator.
- 10Problem-Solving and Data Analysis: percentages, statistics and probabilityRatios, unit conversion, successive percent changes, mean and median, what standard deviation means, conditional probability from two-way tables, scatterplots and margin of error.24 min
- 11Geometry and Trigonometry: shapes, triangles and circlesWhat is and is not on the reference sheet, angles with parallel lines, similar triangles, right-triangle trigonometry, radians, arc length and the circle equation (x − h)² + (y − k)² = r².22 min
- 12Desmos strategies: faster with the calculatorUsing the Desmos graphing calculator built into Bluebook to solve equations and systems by graphing, with sliders, regression, statistics functions and checks for equivalent expressions.18 min
Score strategies
AdvancedPace each module, guess smartly, avoid traps and plan the final week well.
- 13Pacing, guessing and process of eliminationA time budget for each module, the two-pass strategy, Mark for Review, smart guessing with no penalty, and eliminating options in Reading and Writing and in Math.15 min
- 14Avoiding traps and the final-week planThe most typical traps in SAT Math and Reading and Writing, how to guard against them, and a day-by-day plan for the 7 days before the test.15 min
