The Digital SAT draws its questions from 8 content domains, and those domains split into 30 question types. Each page below covers one of them: what the question asks, what it looks like on test day, the mistake that costs the most points, and how to work it. Every page opens a practice set filtered to that skill, so the explanation and the questions are the same subject.
The figures on each page come from College Board's published Assessment Framework. StudyInk is not affiliated with the College Board, and nothing here replaces an official score.
Two modules of 27 questions each, 32 minutes per module. The section scores out of 800 and asks questions from four content domains.

Information and Ideas measures how well you take meaning out of a passage and how well you can tell which evidence backs a claim. The questions stay inside the text you are given, so outside knowledge does not help and often hurts.
About 14 scored questions per form
Craft and Structure is about how a passage is written: the words an author chose, the job each sentence does, and how two authors can look at one subject and reach different conclusions. It asks about the writing rather than the facts.
About 10 scored questions per form
Expression of Ideas asks you to improve a piece of student writing: pick the transition that fits the relationship between two ideas, or choose the sentence that meets a stated rhetorical goal. The notes and sentences you are given are already accurate.
About 13 scored questions per form
Standard English Conventions covers sentence boundaries and the grammar inside a sentence: punctuation between clauses, verb form and tense, agreement, pronouns, modifiers, and parallel structure.
Two modules of 22 questions each, 35 minutes per module. About a quarter of the questions are student-produced responses you type instead of choosing an option.

Algebra is the largest share of the Math section, and it covers linear equations, functions, inequalities, and systems. Most of the questions put a line inside a situation and ask what part of the equation means.

Advanced Math covers equivalent expressions, quadratic and other nonlinear equations, and nonlinear functions. The questions reward reading structure, since the form an expression is written in usually points at the fastest route.
About 6 scored questions per form
Problem-Solving and Data Analysis covers ratios and units, percentages, one-variable and two-variable data, probability, and what a study design allows you to conclude. It is the domain where reading the question carefully matters most.
About 6 scored questions per form
Geometry and Trigonometry covers area and volume, lines, angles, and triangles, right triangles and trigonometry, and circles. Figures are drawn on the Math section, and every given measure is labelled on them.
A diagnostic test puts a band on each content domain, so you can pick the topic page that matches your weakest one instead of guessing.
Reading and Writing and Math figures follow the published operational distribution, which excludes the two pretest questions in each module.
