How we chose the tools
We chose tools that offer useful free access, match the current digital SAT and improve a specific part of your preparation. We ranked official College Board tests and questions highest because they most closely reflect the exam. We then added tools for learning weak concepts, revising content, completing extra questions, getting live help and mastering the built-in calculator.
1. Bluebook: Practise Under Real SAT Conditions
Bluebook lets you take official full-length SAT practice tests in the same app used on exam day. You experience the timed modules, adaptive format and testing tools, including the built-in Desmos calculator. Each completed test produces a score and detailed results.
How it boosts your score: Bluebook gives you the most reliable measure of your current SAT performance. Full-length tests develop your timing and concentration while showing whether you can maintain accuracy across both modules.
When to use: Take one test near the beginning of your preparation to establish your starting score. Space the remaining tests across your study period and complete them under exam conditions. Review every mistake before taking another full test.
2. My Practice and Student Question Bank
College Board’s My Practice shows you exactly what happened on each Bluebook test. You can review every question, check the answer explanations and receive tailored practice based on your results. The Student Question Bank also lets you select official questions by section, skill and difficulty.
How it boosts your score: Every wrong or uncertain answer becomes a clear area for improvement. Targeted sets let you concentrate on the skills costing you points. Official College Board questions give you practice that closely reflects the real SAT.
When to use: Open My Practice after every Bluebook test and review both incorrect answers and questions you guessed. Use the Student Question Bank between full tests, moving towards harder questions as your accuracy improves.
3. Knowt: Get More SAT Practice for Free
Knowt brings several kinds of SAT preparation into one place. You get study guides, flashcards, vocabulary lists, cram sheets, practice questions and full-length mock tests for Math and Reading and Writing. Knowt also uses AI to generate extra questions and create a study schedule based on your needs.
How it boosts your score: You can use its free SAT study resources to review a weak topic and immediately practise it instead of searching across different websites. Flashcards help you remember vocabulary, grammar rules and math formulas. Additional questions give you more opportunities to recognize patterns and correct mistakes.
When to use: Use Knowt between official Bluebook tests for daily study, revision and extra question practice. Keep Bluebook as your main measure of likely test performance, then use Knowt to work on the weaknesses each official test reveals.
4. Khan Academy: Improve Your Weakest SAT Skills
Khan Academy gives you a free way to work on the exact SAT skills you find difficult. You can study a short lesson, watch a worked example, answer practice questions and test yourself with quizzes. Each topic progresses from foundation through to advanced questions.
How it boosts your score: You can spend your study time on the question types costing you points instead of reviewing the entire test. Feedback and explanations help correct repeated mistakes, while advanced exercises prepare you for the harder second module.
When to use: Start after a Bluebook practice test has exposed your weaker skills. Continue until you can answer the advanced questions consistently, then return to timed practice tests to measure your improvement.
5. Schoolhouse.world: Free Live SAT Tutoring
Schoolhouse.world SAT Bootcamps give you free live tutoring in small online groups. Each bootcamp runs twice a week for four weeks. Trained peer tutors explain SAT questions, demonstrate solutions and answer questions during each session.
How it boosts your score: A live tutor can show you why an answer is wrong and identify inefficient ways of solving problems. Regular sessions also keep your preparation moving when independent study becomes inconsistent.
When to use: Join a bootcamp after taking a Bluebook practice test and identifying your weaker section. The four-week format works particularly well during the final month or two before your SAT. Standalone lessons are useful when you need help with one topic.

6. Desmos: Essential SAT Math Calculator Practice
Desmos is a free calculator built into Bluebook for the entire SAT Math section. You can enter calculations, draw graphs, create value tables and see where lines or curves intersect. The graphing calculator also finds zeros, vertices and regression equations.
How it boosts your score: Desmos solves many SAT problems faster than working through the algebra by hand. For example, you can graph two equations and read their intersection to solve a system, or graph a quadratic to find its zeros and vertex. The visual results also make answers easier to check.
When to use: Practice on the College Board version of Desmos throughout your SAT preparation. Use it for systems, quadratics, functions, graphs, data analysis and multi-step calculations. Basic arithmetic may still be faster to complete manually.
