Questions, answered
Is ScholarSAT really free?+
Yes. Every question, every practice test, and every feature is free, with no trial and no premium tier. The project is open source, so anyone can read the code and run their own copy.
Are these official College Board questions?+
No. ScholarSAT's questions are written and generated for this project, following the published structure of the digital SAT: the same domains, skills, and question formats. For official material, we link straight to College Board's free Bluebook tests and question bank.
How are the math answers checked?+
Every math question is built from parameters, and its answer is computed by the program rather than typed by hand. Type-in answers accept any equivalent form, so 0.5, .5, and 1/2 are all marked correct.
How accurate is the predicted score?+
It's an estimate based on your accuracy across ScholarSAT questions and mock tests, weighted by difficulty. Use it to track direction and progress, and use official Bluebook tests for the most realistic benchmark.
Do I need an account?+
No. You can practice from the question bank right away. A free account adds progress tracking, saved questions, mistake review, and full-length practice tests.
Who runs ScholarSAT?+
ScholarSAT is an independent open-source project built on the belief that high-quality test prep shouldn't cost hundreds of dollars. Contributions are welcome on GitHub.
