Understand it. Try it. Prove it.

Thirty checkpoints from “what is this test” to test-day ready, and — where a question trips you up — a short visual path back to the idea, then a fresh question to prove it stuck.

The full road

An order, not a lock — open any stage.

Start Here

What the SAT is, how each section works, and how to set an honest baseline.

0 of 4 complete
  1. Meet the SAT Orientation · ~8 min What the digital SAT is, how it's structured, and why knowing the format is worth real points.
  2. Reading & Writing, explained Orientation · ~7 min Short passages, one question each, four official domains — what the section actually feels like.
  3. Math, explained Orientation · ~7 min The four Math domains, the calculator policy, and why algebra carries the section.
  4. Take a diagnostic & set your baseline Orientation · ~10 min Run one real Bluebook practice test under honest conditions and record where you're starting.

Reading & Writing

Ten checkpoints across all four official Reading & Writing domains, concrete skills first.

0 of 10 complete
  1. Sentence boundaries & punctuation Standard English Conventions · ~14 min Independent vs. dependent clauses, and the five ways the SAT joins or separates them.
  2. Grammar: form, structure & sense Standard English Conventions · ~14 min Subject–verb agreement, pronouns, verb tense, and modifiers — the rules the SAT actually tests.
  3. Transitions Expression of Ideas · ~10 min Pick the logical relationship first, the word second.
  4. Rhetorical synthesis Expression of Ideas · ~10 min The student-notes questions: match the stated goal, ignore true-but-irrelevant facts.
  5. Words in context Craft and Structure · ~10 min Use the sentence's own logic to pick the precise word — not the most impressive one.
  6. Text structure, purpose & cross-text connections Craft and Structure · ~12 min Why the author wrote it, what a sentence is doing, and how two texts relate.
  7. Central ideas & details Information and Ideas · ~10 min Find the main idea without overstating the text.
  8. Inference & command of evidence Information and Ideas · ~12 min The difference between plausible and supported — with text, tables, and graphs.
  9. Reading & Writing strategy Section strategy · ~10 min Pacing, flagging, elimination, and when to move on.
  10. R&W mastery checkpoint All four domains · ~12 min Review all four domains, test yourself, and pick what needs more work.

Math

Foundations first, then the highest-weight domains, then strategy.

0 of 12 complete
  1. Linear equations & functions Algebra · ~15 min Slope, intercepts, and word problems — the single most-tested skill family on SAT Math.
  2. Systems & inequalities Algebra · ~13 min Solutions, no solutions, infinite solutions, and what each looks like on a graph.
  3. Quadratics & polynomials Advanced Math · ~15 min Factoring, roots, the vertex, and reading parabolas.
  4. Exponents, radicals & nonlinear equations Advanced Math · ~14 min Exponent rules, exponential growth, radical and rational equations.
  5. Ratios, rates, percentages & units Problem-Solving and Data Analysis · ~12 min Percent change, proportional reasoning, and unit conversion without panic.
  6. Statistics, data & probability Problem-Solving and Data Analysis · ~13 min Mean vs. median, scatterplots, probability from tables, and what a study can actually claim.
  7. Geometry: lines, angles & triangles Geometry and Trigonometry · ~13 min Angle relationships, similar triangles, and the Pythagorean theorem.
  8. Circles, area, volume & trig Geometry and Trigonometry · ~13 min Circle equations, area and volume, SOH-CAH-TOA, and special right triangles.
  9. Desmos essentials Desmos · ~14 min Graph, intersect, find zeros, build tables — the built-in calculator, from nothing.
  10. Advanced Desmos for the SAT Desmos · ~14 min Regressions, sliders, solving by intersection — and knowing when Desmos is the slow way.
  11. Student-produced responses & Math strategy Section strategy · ~11 min Entering answers correctly, backsolving, estimation, and pacing.
  12. Math mastery checkpoint All four domains · ~12 min Review all four Math domains and rate your Desmos confidence honestly.

Final Stretch

Turn lessons into points: review, drill, and walk in ready.

0 of 4 complete
  1. How to review a practice test Practice · ~12 min The highest-return hour in SAT prep: categorize every miss and log it.
  2. Build your personal drill cycle Practice · ~10 min Diagnose → review → learn → drill → retest, using free official tools.
  3. Full-test strategy & the final week Test day · ~12 min Practice-test spacing, device prep, the break, sleep, and what not to cram.
  4. You're ready — what's next Completion · ~5 min Where you stand, what to keep practicing, and where to get help.
