Take a real SAT practice test. Get a real score. Free.

Yes. Practice Test 4 is completely free: a full-length, timed, two-module SAT Math test with an instant 200–800 score estimate and a domain-by-domain breakdown. No credit card required.

Each test mirrors an official College Board practice test question-for-question: same format, same topic distribution, same difficulty curve, same two-module timing. Every problem is a brand-new variation with different numbers and contexts, so it measures skill, not memory.

That's exactly what Sigma Prep is for. College Board only publishes a handful of official practice tests, and most students burn through them quickly. Sigma Prep gives you 18 full-length tests (6 official-test matches, each in 3 unique versions), so you never run out of realistic, test-day-accurate practice.

Every question has a video explanation showing the fastest way to solve it, not just an answer key. After each test you also get a full review screen with your answers, the correct answers, and your performance by domain.

Yes. After each test, Sigma Prep builds a focused practice set from the specific questions you missed, matched to the same skills and difficulty, with fresh problems. Instead of guessing what to study next, your practice goes exactly where you lost points.

Yes, and retakes are never the questions you already saw. Every test comes in 3 unique versions, so a subscriber's retake serves a fresh version of the same test: same skills and difficulty, different problems. That makes a retake a real measurement instead of a memory check.
