We use AI as a tool, but humans create the content. Every question is reviewed by top-scoring experts and then edited and validated for quality. Most importantly, Test1600 was built specifically for the Digital SAT-not recycled from old materials-so the format, style, and difficulty closely match the real exam. On top of that, our system lets you target specific topics and drill them until they become automatic.

Very close. We’ve replicated the Digital SAT’s structure and adaptive behavior, so your practice score typically falls within a tight range of your official score. The only thing no platform can perfectly predict is the College Board’s test-day scoring curve and other scoring nuances.

It’s based on your real performance, not comparisons to “average students.” Every question you answer-lessons, drills, and full tests-feeds the model data about your strengths, weaknesses, difficulty level, and consistency. The more you practice, the more precise your predicted score becomes.

It works-because it helps you practice consistently. Higher scores come from repetition and routine, so we built the experience around a simple loop: practice → get instant feedback → earn rewards → feel motivated to keep going. Streaks, daily goals, leaderboards, and more help you build discipline and momentum.

Khan Academy is an excellent free library. Test1600 is a system designed to drive results. We focus on one thing: raising your SAT® score. The platform adapts to your level, gives you targeted practice, adaptive tests, and a clear plan-so you study more efficiently and consistently instead of just consuming content.

Both. If you have time, our structured Study Paths guide you step-by-step with low stress. If you’re short on time, you can take full-length adaptive tests, drill only the skills you need with Targeted Practice, and speed things up with expert explainer videos. One subscription-use it your way.

Then you’ll get a lot out of it. We have plenty of high-difficulty questions and time-saving modes: you can drill only “Hard” questions in the exact skills you want, and even focus on the toughest content (like hard Module 2-style practice) to polish what matters most.

Test1600 is fully optimized for mobile, so you can study anywhere. Your progress syncs across devices, which makes it perfect for quick daily sessions and keeping your streak going.
