High-quality SAT® practice was hard to find—so we built it.
I'm a parent and an engineer. Consistent practice is how one obtains high scores on the SAT[1]. When my son ran out of official practice tests, we couldn’t find other options that felt like the real exam—even when we were willing to pay. So I built one.
I deconstructed the Digital SAT® to map recurring patterns and difficulty cues, then built a question bank and reviewed each item against benchmarks for tone and difficulty.
Over several weeks, my son improved by ~200 points.*
Most students aiming for high scores and those who retake the SAT® often run out of realistic practice; JustLockedIn is the affordable add-on families use for the high-quality reps that improve scores.
*Individual results vary based on baseline, consistency, and test-day factors.
How JustLockedIn fits alongside your current SAT® prep
- Most students rely on official lessons and practice tests or paid prep. Research shows SAT outcomes correlate strongly with access to structured prep and resources.[1]
- Students who take full-length practice tests and do targeted preparation see larger gains than those who don’t.[2]
- Over half of students retake the SAT, and retaking improves scores, superscores, and enrollment outcomes[3]—yet most run out of realistic practice along the way.
While your current test prep and official practice tests lay the foundation and provide baseline benchmark scores, JustLockedIn provides the realistic, high-volume reps needed to turn that foundation into a high score.
10,000+ SAT-style questions and 20 adaptive full-lengths that feel like the real Digital SAT®.
Our engine pinpoints weak patterns in real time so every minute targets what you don’t know.
One-time pricing plus a free-access program for students on free/reduced-price lunch.

Smart tools for your best SAT® score
LockedIn Score™
Practice test scores can be misleading—they don't reveal true preparedness. The LockedIn Score™ goes deeper, measuring your consistency, difficulty progression, and pattern coverage to show you exactly how ready you are for test day.
Adaptive Practice
Stop wasting time on questions that are too easy or too hard. Our adaptive engine analyzes your performance in real-time to identify your strengths and gaps. It serves the exact questions you need to improve, ensuring every minute of practice counts.
Go Beyond Just the "Right" Answer
Don't just learn what the right answer is. Learn why. Our step-by-step explanations show you how to solve the problem—often in multiple ways—and explain precisely why the wrong answers are traps. This is how you stop making the same mistakes.
Adaptive Full-Length Practice Tests
Build endurance and test-day confidence with mock exams that look, feel, and score like the real Digital SAT®. Our tests are fully adaptive and are crafted to cover all question types and patterns across English and Math.
Seamless Test-Day Experience
Our platform meticulously mirrors the official test interface – including the on-screen timer, embedded Desmos calculator, digital reference sheets, annotation tools, and answer eliminator. Practice in the exact environment with the exact tools you'll use on test day, eliminating surprises and letting you focus 100% on the questions.
Frequently Asked Questions
By providing the one thing most students run out of: high-volume, realistic practice. The SAT is a pattern-based test. We've modeled our 10,000+ questions on these exact patterns, so your child practices exactly how the test is built. This targeted repetition is the fastest way to build pattern recognition, fix weaknesses, and master the exam.
Most students improve steadily with regular practice. We recommend two or three short practice sessions on weekdays. On weekends, take a full-length mock test to build endurance. Consistent practice matters far more than cramming — and our platform makes it easy to stay on track.
Yes. We recommend using Khan Academy to learn core concepts and the official College Board practice tests to benchmark your performance.
But Khan Academy is for learning, not training. And you only get a few official tests. Our 10,000+ realistic questions and 20 adaptive tests are what you need to build endurance, perfect your pacing, and prepare for test day without wasting your official benchmarks.
To support the needs of every student, and to ensure there is no repetition. The SAT has 120+ recurring patterns, and students improve fastest by practicing many variations, not repeating the same few questions. Most students also need 5–7 timed tests to build endurance even before they actually optimize for scores, so we provide 20 full mock exams to train pacing, endurance, and confidence.
You get two full-length Digital SAT® mock tests that are yours to keep, forever. You also get 15 days of full access to the rest of the platform, including unlimited practice drills and our LockedIn Score™ tracking. No credit card is required to sign up.
