Get free SAT & ACT tips delivered weekly
Good SAT prep is expensive. A private tutor can run $80–$200 an hour, and a full course from a big-name company often costs more than $1,000. For a lot of families, that’s simply out of reach — which is a problem, because SAT scores are back in the picture at many top universities and still tied to merit scholarships.
The good news: you can prepare for the SAT without paying anything. The catch: the word “free” gets stretched a long way in test prep. Some resources are genuinely, permanently free. Others are a free practice test designed to sell you the paid course, or a trial that expires in a week. They’re not the same thing, and a list that lumps them together isn’t much help when you’re actually trying to study.
So this guide sorts them honestly. We’ll tell you which resources are truly free, which are free-with-a-catch, what each one is genuinely good at, and who each one is right for. We include the big official tools, the well-known prep companies, and the newer free platforms — including our own, Preppinbee, which we’ll be upfront about.

*Preppinbee includes a tutor marketplace where individual tutors set their own terms; some offer free help, but tutoring is not categorically free. **Schoolhouse tutoring is peer-led by trained high-school volunteers. “Truly free” means you can prep long-term at no cost and without a credit card. Details below — and always worth verifying directly, since offerings change.
We’ll be straight about our own bias here, then let the facts stand: Preppinbee is a completely free SAT and ACT prep platform — no trial, no credit card, no paywall on the things that matter. You get full-length practice tests in the real Digital SAT format, 10,000+ practice questions, AI-powered study recommendations that tell you what to work on next, a performance dashboard, and access to a community of students and tutors.
The platform also includes a tutor marketplace where individual tutors set their own terms — some offer free help, others charge. That’s an honest distinction: the platform, practice, AI guidance, and community are free for every student; tutoring availability and pricing depend on the individual tutor.
What makes it different from the other free options: it combines the things they each do separately. Khan Academy is free but has no tutors. Schoolhouse has free tutoring but relies on volunteer availability. The paid companies have tutors but put them behind $1,000+ paywalls. Preppinbee puts free practice, AI guidance, and a tutor marketplace in one place, at no cost to students or parents.
Best for: students and parents who want a complete, genuinely free prep experience — practice, guidance, and human help — without a trial running out.
This is the official source — the people who actually make the SAT. The Bluebook app is the exact software students use on test day, and it contains full-length, adaptive official practice tests (currently seven, with more added over time). There’s also an official Question Bank of real past questions. Nothing prepares you for the interface better, because it is the interface.
The limits: the official practice test supply is finite, the Question Bank can be clunky to navigate, and there’s no human help or detailed coaching on why you got something wrong — just the questions and your score.
Best for: everyone, as a non-negotiable starting point. Take an official Bluebook test first to get your real baseline.
The best-known free option, and deservedly so. Khan Academy is an official College Board partner, so its Digital SAT practice is built around real, on-format questions. Create a free account and it builds a personalized practice path based on your diagnostic results, with video lessons covering the concepts behind each question type. No login tricks, no paywall.
The limits: for full-length adaptive tests you’re pointed back to Bluebook, and there’s no live human element — no tutor, no community to study alongside. It’s an excellent solo resource, but it’s solo.
Best for: self-motivated students who want free, official-quality lessons and personalized practice and are happy studying independently.
Founded by Khan Academy creator Sal Khan, Schoolhouse is a nonprofit offering completely free, live, small-group SAT tutoring over Zoom. Their four-week SAT Bootcamps and focused sessions are led by trained, certified peer tutors — high-schoolers who recently scored in the top percentiles themselves — and it’s paired with a genuinely supportive community. College Board even partnered with them to expand free tutoring access.
The limits: tutoring is peer-led volunteer support rather than professional instruction, sessions run on a schedule with limited spots that fill up near test dates, and it leans on official materials for the practice itself rather than its own question bank.
Best for: students who learn best with live, human, small-group support and can work around a session schedule.
Kaplan is a long-established prep company, and its free offering is a single on-demand full-length practice test with a score report, plus extras like a Question of the Day and a short timed “workout.” The test itself is solid and realistic, and the score report gives you a useful breakdown of strengths and weaknesses.
The catch: the free piece is essentially a sample. The actual prep — courses, tutoring, the deeper question banks — is paid, and often expensive. The free test is genuinely useful, but it’s designed to lead toward the paid product.
Best for: taking one extra realistic practice test and score report, on top of your free official ones.
Similar shape to Kaplan. The Princeton Review offers a free full-length practice test with a score report, plus free strategy sessions and webinars on test-taking and admissions. The strategy content is genuinely informative if you catch a live session.
The catch: their core self-paced program is paid, with a 14-day trial rather than a permanently free tier. As with Kaplan, treat the free pieces as a useful supplement, not a full prep plan.
Best for: an additional practice test plus free strategy webinars.
UWorld is well-regarded for the quality of its questions and its detailed answer explanations — many students rate the explanations among the best available. The on-screen experience closely mirrors the Digital SAT.
The catch: the “free” is a 7-day trial, after which it’s a paid subscription. No credit card to start, but the clock is real — this is a paid product with a sample, not a free resource.
Best for: a short, intensive trial if you want to sample premium-quality explanations close to test day.
Magoosh is an affordable, well-liked prep company, and it publishes a useful set of free materials on its blog: study schedules, strategy guides, an introduction to the question types, flashcards, a Question of the Day, and YouTube tutorials. It’s a good free supplement, especially for study planning.
The catch: the structured course, the full question bank, and the score-improvement guarantee are paid. The free pieces are scattered across the blog rather than a single coherent free product.
Best for: free study-planning resources, flashcards, and strategy reading alongside another main resource.
The smartest free approach isn’t picking one resource — it’s combining them well. Start with an official Bluebook test from College Board to get your true baseline. Use that to find your weakest areas. Then pick a main resource that tells you what to work on and lets you practice it: Khan Academy if you want to study solo, Schoolhouse if you want live human help on a schedule, or Preppinbee if you want practice, AI guidance, and a tutor marketplace together in one free place.
Whatever you choose, the rule that matters most is reviewing your mistakes — understanding why a wrong answer was wrong — not just racking up question count. That’s the part free resources vary on most, and it’s where the score actually moves.
Full practice tests, thousands of questions, AI study guidance, and a tutor marketplace — free for students and parents. No trial, no credit card.
