Full disclosure: I built FreePracticeSAT, one of the eight sites below. I have tried to be fair to every site, including the ones that compete with mine, and to be plain about where mine falls short. Prices and free features were checked on each site on October 12, 2026, and they change, so check before you pay for anything.

Bluebook is the College Board app you will take the real SAT in, and it holds the official full-length practice tests. They are timed like the real test and adaptive, so the second math module gets easier or harder depending on how you did in the first. After a test you can see your scores and review the questions in My Practice, and send yourself to Khan Academy for targeted work.
Best for: your first baseline test and your last few rehearsals before test day.
The Student Question Bank holds thousands of official questions. You can filter them by section, content domain, skill and difficulty, so you can spend an hour on exactly one type of question. You sign in with a College Board account.
Best for: targeted practice once you know which skill is weak.
Khan Academy's SAT course was built in partnership with College Board. It covers every skill at three levels (Foundations, Medium and Advanced), with short video walk-throughs, quizzes, and a Course Challenge that helps you decide where to start. It can also walk you through every question on a Bluebook practice test you have taken.
Best for: learning or relearning a skill from the beginning.

Schoolhouse.world is a nonprofit founded by Sal Khan. In partnership with College Board, it runs free SAT bootcamps on Zoom: small groups that meet twice a week for four weeks before each SAT date, led by trained peer tutors who scored 700 or higher on that section.
Best for: students who work better with a person and a group.
FreePracticeSAT gives you unlimited full-length SAT math tests in the real format: two timed modules of 22 questions, a built-in Desmos calculator, and a choice of easy, medium, hard or mixed difficulty. It draws on more than 4,700 practice questions. What it does differently is the diagnosis. For each question you miss, it names the specific mistake behind your wrong answer, and after a second test it shows the basic skills underneath those mistakes. A free Foundations course checks the basics the SAT assumes you know. Worked solutions for every question and the full diagnosis cost \$29, one time.
Best for: students who are stuck at the same score and want to know exactly why.
OnePrep has a large bank of more than 4,000 digital SAT questions, full-length tests, a study planner, analytics, and an AI tutor that explains questions. The free plan is limited: some practice questions and one full-length test. Paid plans are one-time payments that run until a test date. For the November 2026 SAT, Plus costs \$115 and Pro costs \$131.66.
Best for: students who want one paid platform for both sections.
UWorld is not free, but it is the paid site students mention most, so it belongs on the list as a benchmark. Its question bank has more than 1,700 SAT-style questions, and each one comes with a step-by-step explanation that also covers why the wrong answers are wrong. The question bank starts at \$99 and the full course at \$299. There is a 7-day free trial.
Best for: strong students who have used up the official material.
PrepScholar sells a paid SAT program, but its blog has free written guides on every SAT math topic, plus lists of other free resources.
Best for: reading a quick explanation of one topic.
You do not need all eight. As a math teacher, this is the order I would give a student who has a month or more:
Paying for a site makes the most sense once you have worked through the free material and still need more questions. Many students reach a strong score without paying for anything.
Want to know which mistakes are costing you points? It takes one free practice test.
