How it works

LockedIn 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 how ready you really are for test day. Build skills, close gaps, and watch your score climb.

Adaptive Practice

Improve faster with practice that adjusts to you. Adaptive mode identifies your strengths, targets your weaknesses, and selects the right question at the right moment — so every minute you spend leads to measurable score growth. Whether you're drilling a specific skill or training across an entire section, JustLockedIn guides you toward complete mastery with smart, efficient, and personalized practice.

Adaptive Full-Length Practice Tests

Build true test-day confidence with mock exams that look, feel, and score like the real Digital SAT®. Our adaptive tests reveal your exact strengths and weaknesses, show you where to focus next, and help you raise your score faster. Review every question to turn mistakes into mastery—and walk into test day fully prepared.

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.

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 stamina. Consistent practice matters far more than cramming — and our platform makes it easy to stay on track.

Yes — and you should. We recommend using Khan Academy to learn core concepts and the official College Board practice tests to benchmark your performance. They are the gold standard.

The challenge isn't quality — it's mastery. Most students need 5–7 full-length timed tests to build stamina, sharpen pacing, and master every question pattern. Because the number of official tests is limited, you don't want to use them all too early.

JustLockedIn helps you achieve mastery. Our unlimited, realistic practice builds stamina, perfects pacing, and reinforces every skill through repetition. Then, when you take the official tests for benchmarks, you're ready to perform at your best — not practice on them.

Authentic means our questions match the SAT's tone, logic, difficulty, and structure. The SAT is a psychometric exam — not just a knowledge test — so we write questions that mirror how a question on the SAT would be asked, not just what it asks. This is very important to understand if you are trying to improve your score.

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 stamina even before they actually optimize for scores, so we provide 20 full mock exams to train pacing, endurance, and confidence.
