SAT prep is boring. We made it a competition. SAT99 turns SAT prep into a game you actually want to play. Answer real SAT-style practice questions, get instant feedback with a full explanation, and climb a live leaderboard against everyone else prepping for test day. BUILD YOUR STREAK Answer questions correctly back-to-back and watch your streak climb. Miss one and it resets — so every question in your study session matters. Consistency is how you climb, not cramming the night before your exam. COMPETE ON THE LEADERBOARD Track your rank three ways: correct answers, correct-answer streak, and full practice test score. Share your streak card and see exactly where you stand against other students. WRONG OR RIGHT, WE'LL TELL YOU WHY Every practice question comes with a clear, step-by-step explanation — like having a tutor built into the app. Questions adapt as you play, zeroing in on your weak spots across Algebra, Advanced Math, Problem-Solving & Data Analysis, Reading Comprehension, and Grammar. FULL-LENGTH TIMED PRACTICE TESTS When you're ready, take a complete simulated digital SAT: four timed modules (Reading & Writing and Math, two modules each) with real test timing. Submit for scoring and see your Reading/Writing and Math scores ranked against the leaderboard — the closest thing to game day before game day. SET YOUR SCORE GOAL Tell us what you're playing for — a solid score, a target school, or a shot at scholarships — and SAT99 tracks your progress toward it, with a projected score once you've logged enough questions. Whether you're aiming for a 1200 or chasing a 1500+, SAT99 makes exam prep feel like progress instead of a chore. Free trial included, then continues as an auto-renewing subscription.
