Most SAT® prep is based on mindless repetition. We built a Smarter system that actually improves scores.

I'm a parent and an engineer. When my son ran out of official practice materials, 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 and found over 120 recurring patterns: The same question patterns repeat in every test, just structured with different contexts and numbers. I mapped every pattern, built a set of questions around them, and created a system that tracks which patterns a student has mastered and which they haven't.

Over several weeks, my son improved by ~200 points.*

That work is now expanded into JustLockedIn - the practice system families use for the high-quality reps that improve scores—at a price that makes sense.

Students aiming for high scores or retaking the SAT need authentic reps and full-length practice tests. We provide them with the intelligent system they need to achieve their target scores.

*Every student is different, but consistent, targeted practice is how you improve on standardized tests.

How Smart Practice turns into Higher SAT® scores

rocket_launch
Train, don't just learn. We skip videos re-teaching school content. Instead, we train you to solve every question type at every difficulty level, under real test conditions.
target
Smart practice beats random practice. Most prep platforms walk you through questions in no particular order. Our adaptive system identifies your weak areas and prioritizes them, so every question moves you forward, not sideways.
school
Learn the method, not just the answer. Every explanation teaches you how to solve an entire class of problems. In English, we break down grammar rules and rhetorical patterns. In Math, we show multiple solution paths so you recognize the fastest approach.
pattern
Master the patterns that move points. Our adaptive engine tracks your mastery against 120+ recurring Digital SAT patterns and closes gaps in real-time. You don't see pattern labels—you just practice questions while our system ensures comprehensive coverage behind the scenes.
assignment
Practice tests that feel like test day Full-length tests are calibrated to match Bluebook® tone, structure, difficulty, and pacing. Each test maximizes pattern coverage so you are well prepared to achieve your target score. Build the stamina and endurance you need for the real exam so you walk in ready—with no surprises.
verified
Know exactly what you've mastered. See your performance by skill and difficulty, not an opaque "predicted score." Know which areas need work. Know when you're ready.

The smart tools behind faster improvement

LockedIn Score

LockedIn Score™

Practice test scores can be misleading—they don't reveal true proficiency. The LockedIn Score™ goes deeper, measuring consistency, difficulty progression, and pattern coverage so you know exactly how ready you are for test day.

Track mastery by topic—not just overall scores

Adaptive Practice

Our adaptive engine automatically selects questions in real-time to maximize coverage of every pattern and difficulty level. It combines our 10,000+ question bank with sophisticated statistical analysis to ensure every practice session moves you closer to your target score.

Every question adapts to your performance as you practice

Answer Explanation

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 each problem—often in multiple ways—and explain why the wrong answers are designed to trap you. This is how you stop repeating mistakes.

Tests that feel like test day

Build endurance and test-day confidence with practice tests that look, feel, and score like the real Digital SAT®. Our 20 full-length tests are fully adaptive and strategically crafted to cover all 120+ question patterns across English and Math.

Test Interface

Seamless Test-Day Experience

Frequently Asked Questions

By providing the two things students need to achieve their highest score: comprehensive practice with authentic questions, and realistic full-length practice tests. 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.

We help you achieve your highest score through smart, targeted practice. Most platforms either focus on content learning (video lessons) or serve random questions from topic-organized banks. JustLockedIn is different: we analyzed the Digital SAT to map 120+ recurring question patterns, then built thousands of authentic questions around them. Our adaptive system tracks which patterns you've mastered at what difficulty level and automatically serves practice for the ones you haven't.

Yes. Our adaptive system serves questions at the right difficulty for each student—whether you're starting at 1000 or pushing for 1550+. The 120+ mapped patterns ensure comprehensive coverage from foundational concepts to advanced problem-solving. Students struggling in specific areas get targeted practice there, while high scorers get challenged with harder variations. And the system is designed to push you higher.

No—and that's by design. The 120+ patterns are our internal framework for organizing the SAT, not something students memorize. Our adaptive system automatically ensures you practice all patterns at the right difficulty, tracking your mastery behind the scenes. You just focus on solving questions, while we handle the pattern coverage. This eliminates cognitive overload while ensuring comprehensive preparation.

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 ensure you never see the same question twice. 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 practice exams to train pacing, stamina, and confidence.

You get two full-length Digital SAT® practice 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.

There is no catch. We were tired of the subscription model. You pay one time for the access duration you choose (3, 6, or 12 months). You get full access for that entire period.

There are no recurring charges, no auto-renewals, and no hidden upsells.

Yes — within 7 days. If you are not satisfied, email [email protected] and we will be happy to help. We recommend using the free trial first before purchasing.

Yes. You can practice on desktop, laptop, tablet, or mobile using the same account. We recommend a laptop or Chromebook for the most realistic test-day experience.
Note: Accounts cannot be shared. The adaptive engine relies on your specific performance data to customize the difficulty. Sharing accounts between students compromises the adaptive system's ability to target each student's specific weaknesses.
