The SAT Question Bank: what’s in the official one, and where to practice after it

Short answer: College Board’s SAT Question Bank is free and has 1,876 official Math questions, each with a written rationale. Use it first. When you have worked through it, Sigma Prep’s bank gives you 7,300+ SAT Math questions in the same 19 skills and 3 difficulty levels, with a video solution on every one.

College Board’s official SAT Question Bank

The SAT Suite Question Bank is College Board’s free library of official practice questions. You filter by section, domain, skill and difficulty and get each question with its answer and a written rationale. For Math it holds 1,876 questions (our count, September 2026), sorted into the same 4 domains and 19 skills the test reports.

It changes. In August 2026 College Board added 196 new Math questions; we found every one and solved all 196 on video. Our count of how often each skill appears on real tests, against the whole bank, is in the most common SAT Math questions.

How to use it well

• Work by skill, not at random: pick the skills you miss and filter to them.
• Get Easy and Medium solid first, then move to Hard. Easy and Medium misses are the cheapest points on the test.
• Keep the Bluebook practice tests for timed, full-length practice, so you are not seeing their questions for the first time on test day.
• Redo every miss a few days later, without looking at the rationale first.
