Digital SAT prep that
adapts like the real test.
PrepGraph is an AI tutor for the Digital SAT. It sets your target score, finds your gaps in Reading and Writing and in Math, and gives you step-by-step explanations and practice aimed at those gaps, adjusting as you improve, the way the section-adaptive test itself does.
Next official administration: Saturday, December 5, 2026. Regular registration closes Friday, November 20, 2026 — about 15 days before test day.
One tutor that remembers — from grade 6 to your test, then to college and career skills. The science behind the tutor’s memory.
The Digital SAT at a glance
A lot of SAT advice still describes a test that no longer exists. Here is the test as it is given and scored today.
| Section | Time | Questions | Scored | Score range |
|---|---|---|---|---|
| Reading & Writing | 64 min (2 × 32) | 54 | 50 | 200–800 |
| Math | 70 min (2 × 35) | 44 | 40 | 200–800 |
| Total | 2h 14m | 98 | 90 | 400–1600 |
It's section-adaptive, and that changes your preparation
Each section is delivered in two modules. How you perform on module 1 determines whether module 2 routes you to the harder or the easier set of questions — so early accuracy carries more weight than it did on the old paper SAT, and pacing on module 1 is worth training on purpose. One thing we will not tell you: the exact score ceiling of the lower-difficulty module 2. College Board has never published one, and every number in circulation is a guess.
Also worth internalizing: of the 98 questions you see, only 90 are scored — the rest are unscored pretest items you cannot identify — and there is no penalty for a wrong answer, so a blank is strictly worse than a guess.

How PrepGraph helps you prepare
Score-target driven
Tell PrepGraph your SAT goal — it builds a plan that gets you there.
Diagnoses hidden gaps
Finds weak question types early across Reading, Writing, and Math.
Tells you what to study next
Every day, clear next steps based on your target and progress.
Timed practice that adapts
Section-timed practice and adaptive difficulty matched to your level.
Start in 3 simple steps
Set a target score
Tell PrepGraph the score you're aiming for. The plan works backward from that number, not from a generic syllabus.
Get diagnosed
Practice sets and assessments find the specific question types you miss — inference questions, transitions, systems of equations — rather than the broad section you are "bad at".
Work through it with the tutor
When you get stuck, the AI tutor walks the full solution step by step — in text or out loud with Voice Learning — then hands you a similar question to check that it stuck.
For your parents
Weekly progress reports via email — automatically.
Practice consistency
Parents see how many days this week their student practiced across Reading & Writing and Math.
Weak areas identified
The specific question types that need more work — visible before the next practice test.
Score trend tracking
Performance trajectory over time, so parents see improvement — not just a single number.
What it costs
The straight answer — full plan details on the pricing page.
SAT/ACT Pass — 3 months — 3 months of everything. One payment, no auto-renewal, full access through your test window.
Planning more than one sitting? The SAT/ACT Pass — 6 months is $249 one-time — a full season with retakes, loaded with 26,000 credits (~96 hours of one-on-one AI tutoring). Or go monthly instead: Basic from $19.99/month, or Plus at $49.99/month with more tutoring time — cancel anytime.
Free trial: about 1–1.5 hours of voice tutoring, to use within 7 days. No card. It covers Voice Learning, Mastery Loop and Ask Doubts, before you pay anything.
For comparison: private SAT tutors typically charge $50 to $200 an hour — your entire 3-month pass costs less than three hours of tutoring, and it works with you every day.
SAT questions, answered honestly
Will an AI tutor raise my SAT score?
No one can promise you a number, so we do not offer score guarantees. What moves scores is diagnosing the question types you actually miss, understanding why you miss them, and practicing those under time. An AI tutor makes that loop faster and cheaper than it would otherwise be. It does not do the work for you.
How is the Digital SAT scored?
Your total is 400 to 1600, made up of two section scores of 200 to 800 each: Reading and Writing, and Math. Not every question counts. Reading and Writing has 54 questions but only 50 are scored, and Math has 44 questions but only 40 are scored — the rest are unscored pretest items being trialed for future tests, and you cannot tell which ones they are. There is no penalty for a wrong answer, so never leave a question blank.
How does the Digital SAT being adaptive change how I should prepare?
The Digital SAT is section-adaptive. Each section arrives in two modules, and how you perform on the first module determines whether the second module you are routed into is the easier or the harder one. The practical consequence is that the first module carries unusual weight — a shaky start narrows the ceiling for the rest of the section. That makes accuracy and pacing on early questions worth training deliberately. Be careful with the specific "score cap" numbers that circulate online for the lower-difficulty module: College Board has never published one, and every figure you will see quoted is somebody’s guess.
Does PrepGraph replace official Bluebook practice tests?
No, and be suspicious of any AI tool that says it does. Full-length official Digital SAT practice tests live in College Board’s Bluebook app, they use real retired questions, and they are the only place you get an authentic run at the real adaptive engine. Take them there. Use PrepGraph for the part Bluebook does not do: working out why you missed what you missed, and fixing it before the next one.
