The most important distinction in SAT preparation materials is between official and unofficial resources. Official materials — produced by the College Board, which creates and administers the SAT — are the most accurate representation of what you will see on test day. Unofficial materials from test prep companies and publishers vary widely in accuracy. For core preparation, official materials should be your primary foundation.
Bluebook is the College Board's free app for the digital SAT (the current format of the SAT, fully digital since March 2024). Bluebook contains full-length adaptive practice tests that simulate the actual digital SAT experience, including the adaptive test format (where your score on the first reading/writing or math module determines which difficulty level you receive in the second module). Bluebook is the most accurate practice experience available for the digital SAT and is available free from the College Board website. If you can only use one resource, use Bluebook.
The College Board provides free full-length practice tests through Bluebook and through the College Board's SAT practice website. As of 2025, the College Board has released multiple digital SAT practice tests. These tests use the same question formats, difficulty levels, and adaptive structure as the actual exam. Completing 3 to 5 full-length practice tests under timed conditions, with thorough review of wrong answers, should be the centerpiece of any SAT preparation plan.
The College Board publishes The Official SAT Study Guide as a book containing practice tests and explanations. The digital edition and online access are available through the College Board website. While Bluebook provides the most realistic digital test experience, the printed guide is useful for students who prefer working through problems on paper. Note that the Official Study Guide primarily covers the digital SAT format — older editions covering the paper SAT are less relevant to current test-takers.
SAT vocabulary appears primarily in the Reading and Writing section, where questions ask you to select the best word or phrase to complete a sentence or to identify how a word is used in context. The digital SAT's vocabulary questions differ significantly from the old paper SAT — they focus more on context-dependent word choice and less on obscure, memorization-based vocabulary.
The digital SAT's Reading and Writing section includes 'Words in Context' questions that present a word or phrase in a passage and ask which answer choice most closely matches its meaning or best completes a blank. These questions reward understanding how words function in context rather than pure memorization. The vocabulary that appears in these questions tends to be academic and domain-general — words that educated adults use across various fields — rather than arcane or highly specialized terms.
Rather than memorizing arbitrary word lists, focus on these high-yield vocabulary categories: transition words and discourse markers (moreover, nevertheless, consequently, despite, although — words that signal argument structure and relationships between ideas); academic verbs that express stance and reasoning (assert, contend, demonstrate, challenge, refute, advocate, imply, infer); words related to analysis and evaluation (ambiguous, nuanced, plausible, speculative, corroborate, substantiate); and commonly confused words that appear in Standard English Conventions questions (affect/effect, principle/principal, complement/compliment, comprise/compose).
The most effective way to build SAT vocabulary is through reading — specifically, reading challenging texts like newspaper editorial sections, science journalism (Scientific American, The Atlantic), and literary nonfiction. Words encountered in context are retained more effectively than words memorized from lists. If you use word lists, focus on the SAT's high-frequency academic vocabulary rather than obscure words unlikely to appear. Khan Academy's linked SAT prep includes vocabulary practice integrated into full reading comprehension exercises.
The SAT Math section covers algebra, advanced math (quadratics, functions, exponents), problem-solving and data analysis (statistics, ratios, percentages), and geometry/trigonometry. A calculator is permitted on all Math questions in the digital SAT (unlike the old paper SAT, which had a no-calculator section). The built-in Desmos graphing calculator is available within the Bluebook app.
Khan Academy offers the most comprehensive free SAT Math preparation available. Khan Academy's partnership with the College Board means SAT practice on Khan Academy uses actual official SAT questions. The adaptive practice feature identifies your weakest math skill areas based on your practice test performance and serves targeted practice problems. For most students, Khan Academy combined with Bluebook practice tests provides all the SAT Math preparation needed.
Focus preparation on: linear equations and systems of equations (most heavily tested); quadratic equations (factoring, quadratic formula, completing the square); functions (interpreting function notation, transformations, composition); statistics (mean, median, range, standard deviation concepts, interpreting data displays); ratios, rates, and proportional reasoning (word problems converting units and solving proportions); geometry (area, perimeter, volume formulas; angle relationships; right triangle trigonometry — SOH-CAH-TOA); and exponential growth/decay models. Questions testing pure arithmetic or basic computation are rare — most questions require setting up and solving algebraic equations from word problems or data.
The Desmos graphing calculator (built into Bluebook during the actual digital SAT) is extremely powerful for SAT Math. Practice using Desmos for: solving systems of equations by graphing, visualizing quadratic functions to find zeros and vertex, checking solutions algebraically, and converting between geometric and algebraic representations. Many students who practice using Desmos effectively find that it significantly reduces the time needed to solve calculator-appropriate problems.
Strong SAT preparation does not require expensive paid courses. Several high-quality free resources provide comprehensive preparation for the digital SAT.
Linking your College Board account to Khan Academy provides personalized SAT practice based on your actual PSAT or SAT scores. Khan Academy then generates customized practice recommendations targeting your specific weak areas. This linking feature means your Khan Academy practice is informed by real test data rather than a generic practice plan. Khan Academy's SAT prep is free, used by millions of students annually, and directly endorsed by the College Board as an official prep partner.
In addition to Bluebook practice tests, the College Board offers: the SAT Question of the Day (daily practice question with explanation), access to official Digital SAT Prep through School Day testing data (if your school administers the PSAT), and free score report analysis showing which skill areas need work. The College Board's free resources are sufficient for many test-takers to achieve their target scores without purchasing additional materials.
PracticeTestGeeks offers free SAT practice tests covering Math and Evidence-Based Reading and Writing. These tests help you practice question formats and build familiarity with SAT question styles. Use practice tests to identify weak areas and track your improvement over your preparation period. For the most accurate practice experience, combine third-party practice tests with official Bluebook full-length tests.
A focused 8 to 12 week study plan is sufficient for most students to achieve significant score improvements on the digital SAT. Here is a structured approach:
Take a full-length Bluebook practice test under timed conditions. Analyze your results: which Math topics did you miss most? Which Reading and Writing question types cost you the most points (inference, command of evidence, words in context, standard English conventions)? Use this diagnostic to identify your 2 to 3 highest-priority study areas. Do not study everything equally — focus your limited study time on the areas with the greatest score-improvement potential.
Use Khan Academy to practice in your weakest skill areas. Spend 45 to 90 minutes per day practicing and reviewing. For Math, work through the specific skill categories where you lost the most points. For Reading and Writing, practice question type by question type — spend one week on inference questions, another on words in context, another on standard English conventions. Review every wrong answer and understand the error pattern before moving on.
Take a full-length Bluebook test every 1 to 2 weeks. After each test, analyze your errors and return to targeted skill practice for the areas that cost you the most points. In the week before your test, take one final full-length practice test for calibration, then stop intensive studying. Get adequate sleep the two nights before your test — sleep deprivation significantly impairs cognitive performance, and the SAT's Reading and Writing section is particularly sensitive to mental fatigue.
