The ranking at a glance

The picks, in order

1. Bluebook (College Board)

Best for: Official full-length digital SAT practice tests. Price (October 2026): Free. Platforms: Windows, Mac, iPad, school-managed Chromebooks.

The College Board's testing app for the digital SAT. It has free full-length practice tests and the same built-in Desmos calculator you get on test day.

Why it ranks here: It is the real test app, and the practice tests are free and official. Nothing else is closer to test day.

Watch out: Practice only, no tutoring. Personal Chromebooks are not on the supported list.

2. Khan Academy Official Digital SAT Prep

Best for: Free SAT lessons and practice made with College Board. Price (October 2026): Free. Platforms: Web.

Free official SAT prep listed by College Board, which says it "will make a study plan for students" focused on what will help most on test day.

Why it ranks here: Free, official, and builds a plan around what you need. Pair it with Bluebook.

Watch out: Practice tests themselves are in Bluebook.

3. Schoolhouse.world SAT

Best for: Free live SAT tutoring in small groups. Price (October 2026): Free. Platforms: Web (Zoom sessions).

Free official SAT tutoring with College Board: 4 weeks, two 75-minute sessions a week, at most 10 learners, led by high school tutors who scored in the 95th percentile or above.

Why it ranks here: Free live tutoring in small groups with College Board, from high-scoring peer tutors.

Watch out: Fixed schedule; peer tutors, not adults.

4. UWorld SAT

Best for: Large bank of hard SAT questions with detailed explanations. Price (October 2026): $299 (30 days) to $449 (360 days); 7-day free trial. Platforms: Web, iPhone, Android.

An SAT course with 1,700+ practice questions, detailed explanations, video lessons, practice tests, flashcards and analytics.

Why it ranks here: The biggest paid question bank here, with detailed explanations; costs $299 and up.

Watch out: Costs more than the free official tools. No live tutor.

5. The Princeton Review SAT Self-Paced

Best for: A structured SAT course with a score guarantee. Price (October 2026): $299 for 365 days; 14-day free trial. Platforms: Web.

Self-paced SAT course with 5 full-length practice tests, 65+ short lessons, thousands of practice questions and score reports, plus a better-score guarantee with conditions.

Why it ranks here: A structured paid course with practice tests and a score guarantee with conditions.

Watch out: Full refund only within 7 days. Live classes cost more.

6. Gemini SAT practice tests

Best for: Free full-length SAT practice with feedback in a chat. Price (October 2026): Free. Platforms: Web, Android, iPhone.

Gemini can give full SAT practice tests with an optional timer and per-section scores, then explain what you missed. The Princeton Review announced the SAT practice tests in Gemini.

Why it ranks here: Free full-length practice tests with feedback, but not the official test app.

Watch out: Not the official test app; use Bluebook for the real test experience.

7. DuckyHelper (our product)

Best for: A live voice tutor that sees and marks up your screen, any subject. Price (October 2026): Free (about 6 min of talking a week); Plus $20/month; Pro $200/month; Unlimited $200/week. Platforms: Web app in any browser, including Chromebooks and Windows; Mac app (macOS 14+, Apple silicon).

A live voice tutor. Talk to Ducky and it sees your screen, explains out loud, and shows you: in the web app it draws marks on the preview of a tab, window or screen you share; in the Mac app it draws circles, arrows and labels right on your real screen and walks you through steps in your own apps, checking each one. Both make quizzes, worked steps, interactive graphs and pictures; flashcards, simulations, maps, timelines and the code runner are Mac app only, and longer practice tests are web only. A dashboard tracks time learned, streak, topics, mastery and test scores.

Why it ranks here: Good for the step after a practice test: talk through each missed question on your screen, get quizzed on the same skill, and track scores in the dashboard. It does not have its own question bank or practice tests.

Watch out: New, with no track record yet. The free plan is small, and you get far less talking time per dollar than with chat apps. Drawing on your real screen, step checks inside other apps and flashcards are Mac only. No phone app. Under 13 only with verified parental consent.

8. Desmos

Best for: Free graphing calculator, the same one built into the SAT. Price (October 2026): Free. Platforms: Web.

Desmos calls itself "Beautiful free math". The College Board builds the Desmos calculator into Bluebook for the whole SAT Math section, so practicing with it pays off.

Why it ranks here: Not prep by itself, but the calculator is built into the test, so learning it saves time.

Watch out: A calculator, not a tutor.
