What Is on the SAT 2026? Complete Digital SAT Content and Topics Guide

What Is on the Digital SAT? Overview

The Digital SAT has two sections: Reading and Writing (54 questions) and Math (44 questions). Each section is divided into two adaptive modules. The test does not have a separate science section — science reasoning questions are embedded in the Reading and Writing section as informational text passages about scientific topics. The SAT does not test specific history or social studies content knowledge — it tests reading comprehension using historical and social studies passages, but you don't need to memorize historical facts to answer the questions correctly.

The Digital SAT replaced the paper SAT in 2024. The paper SAT had five sections: Reading, Writing and Language, Math (No Calculator), Math (Calculator), and optionally an Essay. The Digital SAT eliminated the No-Calculator section (all math now allows calculators, including the built-in Desmos graphing calculator) and eliminated the Essay section entirely. It also replaced long 500-750 word reading passages with short 25-150 word passages, each paired with one or two questions. These changes make the Digital SAT a meaningfully different experience from the old paper test — students using pre-2024 prep materials should be aware that the content format has changed.

The SAT is not primarily a knowledge test — it is primarily a reasoning and skills test. The Reading and Writing section does not require you to memorize literary terms, historical events, or scientific facts. The Math section does require knowledge of specific formulas, theorems, and procedures — but all these are predictable and finite. The reference sheet provided on test day covers some math formulas, but others (like the quadratic formula, trig identities, and common algebraic rules) are not provided and must be memorized. The sat formula sheet lists every math formula you need, both those provided and those you must know.

Understanding what is on the SAT helps you allocate prep time efficiently. Students who spend equal time on every topic often underperform compared to students who analyze their score report, identify their 2-3 highest-miss skill areas, and spend 80% of prep on those specifically. After taking a full-length practice test (use Bluebook, the free official College Board platform), review every missed question categorized by skill domain. Your personal weak areas matter more than a generic topic ranking. For full practice tests, see our sat test resources. For understanding the question count in each section, see how many questions are on the sat.

Reading and Writing: What Topics Are Tested

The Reading and Writing section tests four skill domains, each covering a defined percentage of the 54 questions. Craft and Structure (~28%) tests your ability to understand vocabulary in context, analyze the structure of a text, and make connections between two related passages. Vocabulary questions on the Digital SAT do not ask you to define obscure words from a list — they give you a word in context and ask you to choose the word from four options that best fits the specific meaning in that passage. This is a fundamentally different skill than rote vocabulary memorization.

Information and Ideas (~26%) tests reading comprehension: identifying the central idea of a passage, finding key details, interpreting tables and graphs paired with text, and evaluating command of evidence — how well an author supports their argument. Evidence questions often pair a text with a graph or data table and ask you to identify which choice best uses the data to support or complicate a given claim. Students who struggle with data interpretation benefit from practicing these question types specifically.

Expression of Ideas (~20%) tests rhetoric and synthesis: choosing the most effective way to transition between ideas, selecting wording that achieves a specific rhetorical goal (e.g., emphasizing a contrast, providing an example, drawing a conclusion), and completing a synthesis task — choosing the text that best synthesizes two provided perspectives. These questions require understanding authorial intent and rhetorical purpose, not just factual accuracy.

Standard English Conventions (~26%) tests grammar, usage, and punctuation. This is the most directly teachable domain — grammar rules are consistent and learnable through targeted practice. Key topics: subject-verb agreement, pronoun agreement, punctuation with independent and dependent clauses (commas, semicolons, colons, dashes), dangling and misplaced modifiers, parallel structure, and correct use of apostrophes. Students who are natural readers often underinvest in grammar practice and find this is where they lose the most points. Deliberate grammar drill on specific rule types typically produces fast score gains in the Conventions domain. For a study guide on the exam format, see what is sat examination.

Math: What Topics Are Tested

The SAT Math section tests four content areas. Algebra (~35% of Math) covers linear equations in one and two variables, systems of equations, linear inequalities, and interpreting linear functions in context. This is the largest single content area on the test, reflecting its importance as foundational math. Students comfortable with Algebra I and II have a strong foundation for this domain. Key algebraic skills: solving for x, interpreting slope and intercept in real-world contexts, setting up equations from word problems, and solving systems of equations by substitution and elimination.

Advanced Math (~35% of Math) covers quadratic equations, polynomial functions, rational equations, radical equations, and exponential functions. This domain requires familiarity with factoring, completing the square, the quadratic formula, and understanding function behavior — increasing/decreasing, maxima/minima, domain and range. Students who haven't taken Algebra II or pre-calculus may find this domain challenging and should prioritize it in prep.

Problem Solving and Data Analysis (~15% of Math) covers ratios, rates, proportions, percentages, unit conversions, probability, two-way tables, and interpreting graphs and statistics. These questions often appear as word problems requiring you to set up a proportion or interpret a graph correctly. The data interpretation skills overlap with Reading and Writing's Evidence questions — students who are strong at interpreting graphs and tables do well in both sections.

Geometry and Trigonometry (~15% of Math) covers area, perimeter, volume, angles, triangles, circles, coordinate geometry, and right triangle trigonometry (sin, cos, tan, the unit circle basics). Trig content on the Digital SAT is more prominent than on the old SAT — know SOH-CAH-TOA and how to apply it to right triangles. The reference sheet on test day includes basic area and volume formulas for common shapes, so you don't need to memorize all geometric formulas. Students often ask whether they should study all four math domains equally or focus on specific areas. The answer depends on your practice test score report. However, as a starting point, Algebra and Advanced Math together make up approximately 70% of Math questions. These two domains alone represent the bulk of the test. Students who master linear and quadratic equations — the core of Algebra and the foundation of Advanced Math — can score well in Math even with gaps in Problem Solving and Geometry. Once Algebra and Advanced Math are solid, adding Problem Solving (ratios, percentages, statistics) typically provides the next highest return because it includes several question types that are predictable and pattern-based. Geometry/Trig questions, while important, represent a smaller portion of the section and often involve formulas provided on the reference sheet.
