Tool by tool

Bluebook

Full-length practice tests in the same app you test in

Bluebook is the College Board app you take the digital SAT in. Its free practice tests adapt like the real exam, and your results show up in My Practice for review.

Strengths

  • The real test screen, timer and built-in Desmos calculator
  • Score reports point to the skills you miss

Limits

  • No lessons: it shows what you missed, not how to fix it
  • No phone app, and a limited number of tests, so use them as checkpoints
Official site

Khan Academy

Free lessons and a study plan, made with College Board

Official Digital SAT Prep on Khan Academy is free. College Board points students to it for a study plan, lessons and quizzes in Math and Reading and Writing.

Strengths

  • Free from start to finish
  • Short lessons teach the skill behind each question type

Limits

  • Its practice sets are not full adaptive tests; take those in Bluebook
  • Can feel slow if you already score high
Official site

College Board Student Question Bank

Drilling real SAT questions one skill at a time

In My Practice, College Board's Student Question Bank holds thousands of real SAT and PSAT questions. It is the best free source for extra drills once Bluebook tests run out.

Strengths

  • Real questions from the people who write the test
  • Thousands of them, so you rarely run out

Limits

  • Plain drills, with no lessons or study plan
  • Needs a College Board account
Official site

UWorld

A large paid question bank with detailed explanations

UWorld sells an SAT question bank with 2,000+ questions and explanations, plus a full course from $299. The web version is built to look like Bluebook, and the apps sync your progress.

Strengths

  • More than 2,000 SAT-level questions, more than most students finish
  • One full mock exam plus up to 9 adaptive tests built from the bank

Limits

  • Paid, and the clock starts when you activate it
  • Questions are written by UWorld, not official SAT items
Official site

StudyPDF

That's us

Practice from your own class notes and prep book chapters

Upload your class notes, prep book chapters or worksheets. StudyPDF builds quizzes, flashcards and practice exams from them and tracks which concepts you keep missing, so the next quiz targets them. Bo, the tutor, explains a question from your files with the page cited. It is practice on your material, not official SAT items. The free plan needs an account but no credit card, and gives you about 4 materials a week.

Strengths

  • Practice on exactly what your class or tutor covered
  • Free browser samplers for the ACT and the PSAT
  • PDF export on every plan, quizzes print as worksheets with an answer key

Limits

  • Not official SAT questions and no adaptive full-length tests
  • Weekly caps on every plan

How we picked

  • We started from what SAT prep needs: practice in the real test format, lessons for weak skills, and plenty of questions.
  • Official free tools come first because they match the test best and cost nothing.
  • Prices come from each vendor's own site, checked October 2026. Prices change, so check before you pay.
  • We sort by use case, not by rank. StudyPDF is one option, with real limits.

More on this

Start with the free official tools. The digital SAT runs in College Board's Bluebook app: two sections, Reading and Writing and Math, each split into two adaptive modules, about 2 hours 14 minutes in total, with a Desmos calculator built in. Practice in Bluebook and nothing on test day will surprise you.

A free plan that works for most students: take one Bluebook practice test, work on your weakest skills with Khan Academy and the Student Question Bank, then retest every two to three weeks. Pay for something like UWorld only when you run out of official questions or want more explanation. Our guide at studypdf.net/answers/how-to-study-for-the-sat has a week-by-week plan.

Taking the ACT instead? ACT links free practice tests from act.org, and students who register with a fee waiver get The Official ACT Self-Paced Course, powered by Kaplan, at no cost. StudyPDF also has free 15-question samplers for the ACT at studypdf.net/quizzes/act-practice-questions and the PSAT at studypdf.net/quizzes/psat-practice-test. Our team wrote them; they are not official items.

Questions and answers

What is the best SAT prep app?

Bluebook for full practice tests and Khan Academy for lessons. Both are free and official. Add the College Board Student Question Bank for more drills, or UWorld if you want a bigger paid question bank.

What is the best free SAT prep?

The official set: Bluebook practice tests, Official Digital SAT Prep on Khan Academy and the Student Question Bank in My Practice. All three are free, and for many students they are all the prep they need.

What is the best ACT prep app?

Start with the free practice tests linked from act.org. If you register with a fee waiver, The Official ACT Self-Paced Course, powered by Kaplan, is free. StudyPDF has a free 15-question ACT sampler.

Is paid SAT prep worth it?

Often not at first. Use the free official tools until your scores stall or you run out of questions. Then a paid question bank or a tutor can help with the skills you still miss.
