"...The practice tests felt exactly like the real Digital SAT on Bluebook. Seeing my LockedIn Score improve for each topic kept me motivated, and I jumped over 150 points! No way I could've done that just reading a book."
What makes JustLockedIn different?

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 then selects the right question, ensuring you're always working on the exact material you need to improve.
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
Students just need to practice consistently and take the mock tests at regular intervals. The SAT is a pattern-based test, and the fastest improvement comes from realistic repetition, skill tracking, and timed practice. JustLockedIn provides a practically unlimited supply of authentic questions and 20 full mock exams — the exact training students need to raise their score with confidence.
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 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 repetiton. 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.
