Free SAT Prep study guides
- Linear Equations in One Variable — Solve one-variable linear equations by preserving equality, translating units, and checking the exact requested quantity.
- Linear Functions — Read and build linear functions across equations, tables, graphs, and contexts by tracking constant rate and initial value.
- Linear Equations in Two Variables — Navigate solutions, forms, intercepts, slopes, and contextual constraints for linear equations in two variables.
- Systems of Linear Equations — Choose substitution or elimination, interpret solution counts, and model two simultaneous linear constraints.
- Linear Inequalities — Solve and graph linear inequalities, preserve boundary logic, and identify feasible regions in context.
- Equivalent Expressions — Rewrite polynomial, exponential, and rational expressions into the form that exposes the feature an SAT question asks for.
- Nonlinear Equations and Systems — Solve quadratic, radical, and rational equations; count roots; reject extraneous solutions; and locate nonlinear-system intersections.
- Nonlinear Functions — Recognize nonlinear families and read their zeros, vertices, growth factors, transformations, domains, and compositions.
- Ratios, Rates, Proportions, and Units — Use unit rates, proportional relationships, dimensional analysis, and scale factors without losing the meaning of the units.
- Percentages — Use multipliers to solve percent-of, percent-change, reverse-percentage, successive-change, and repeated-growth problems.
- One-Variable Data — Choose and interpret measures of center and spread, read distribution shape and box plots, and track outliers and transformations.
- Two-Variable Data and Scatterplots — Describe associations, interpret best-fit models, calculate residuals, and judge interpolation, extrapolation, and causation.
- Probability and Conditional Probability — Build sample spaces, use complements and probability rules, and solve conditional, independent, and without-replacement events.
- Sample Statistics and Margin of Error — Connect samples to populations, identify sampling bias, build margin-of-error intervals, and reason about precision and sample size.
- Evaluating Statistical Claims — Match statistical conclusions to random selection, random assignment, experimental controls, survey quality, and the reported evidence.
- Lines, Angles, and Triangles — Turn marked geometric facts into angle relationships, triangle equations, similarity ratios, and valid side-length conclusions.
- Area and Volume — Decompose plane figures, distinguish surface area from volume, use solid formulas, and track scale factors and units.
- Right Triangles and Trigonometry — Use the Pythagorean theorem, special triangles, trigonometric ratios, inverse trig, similarity, and angle relationships.
- Circles — Connect radius and center to circumference, area, arcs, sectors, angles, tangents, chords, and coordinate equations.
- Central Ideas and Details — Identify the precise claim developed by an entire passage and distinguish it from broad topics and supporting details.
- Command of Evidence: Textual — Choose the textual evidence that most directly supports a claim, conclusion, or interpretation.
- Command of Evidence: Quantitative — Read tables, charts, and graphs precisely, then connect the right value or trend to the claim.
- Inferences — Build the narrowest conclusion the passage supports by combining explicit clues without adding assumptions.
- Words in Context — Use grammar, logic, tone, and substitution to select the exact meaning a word carries in its sentence.
- Text Structure and Purpose — Track how a passage is built and identify the precise job performed by a sentence or detail.
- Cross-Text Connections — Map each author’s position before identifying the exact relationship between two short texts.
- Transitions — Name the logical relationship between ideas before choosing the transition that announces it accurately.
- Rhetorical Synthesis — Turn research notes into one accurate, relevant sentence by letting the rhetorical goal control every detail.
- Boundaries — Classify clauses and sentence parts before choosing punctuation that connects them without fragments or comma splices.
- Form, Structure, and Sense — Master agreement, verb form, pronouns, modifiers, parallelism, possessives, and comparison logic.
