Grind1600 was built with a simple belief: every student deserves access to high-quality SAT prep, regardless of their budget. Too many students spend hundreds — even thousands — on prep courses that offer generic, one-size-fits-all content.
We built Grind1600 to change that. Our platform adapts to each student's strengths and weaknesses, creating a personalized study experience that focuses time where it matters most.

Grind1600 started with a frustration shared by students and educators alike: the SAT prep industry is broken. The most popular platforms charge hundreds of dollars for access, putting effective preparation out of reach for the students who need it most. Even worse, those expensive programs often deliver the same generic content to every student, regardless of where they actually need help.
We saw students spending months studying topics they had already mastered while neglecting the areas that would actually move their scores. We saw families choosing between SAT prep and other essentials. And we saw talented students underperform on the SAT simply because they lacked access to quality preparation.
So we built something different. Every student gets real practice before paying anything: the Daily Challenge with leaderboard, 40 starter questions across all 8 SAT domains, your first full-length practice test, the first days of your personalized study plan, and full progress tracking — no credit card required, and no time limit. When you're ready to go all-in for test day, Pro unlocks the full 1,265+ question bank, every practice test, your complete study plan, and the mistake log for $20/mo (or $144/yr — 40% off annual). That's less than a single hour of tutoring, backed by a 7-day money-back guarantee.
Effective SAT preparation is not about doing more questions — it is about doing the right questions. Grind1600 uses adaptive learning to adjust question difficulty based on your performance in each of the eight SAT domains. As you practice, the platform identifies your strengths and weaknesses with precision, so you spend your study time where it will have the greatest impact on your score.
Our question bank includes over 1,265 questions spanning all four Reading and Writing domains (Information and Ideas, Craft and Structure, Expression of Ideas, Standard English Conventions) and all four Math domains (Algebra, Advanced Math, Problem-Solving and Data Analysis, Geometry and Trigonometry). Every question is calibrated to reflect the difficulty and format of the real Digital SAT, including student-produced response items for Math.
Progress tracking gives you a clear, data-driven picture of where you stand. Your dashboard shows domain-level accuracy trends, time-per-question metrics, and projected score improvements. Study plans are generated based on your target score and test date, then adjust as your performance evolves. Everything is designed to help you study smarter, not just harder.
Grind1600 works on any device with a modern web browser — desktop, laptop, tablet, or phone. There is nothing to download or install. Whether you are studying at home, at school, or at the library, your progress syncs automatically and picks up right where you left off.
We believe that a student's family income should never block access to good test prep. The Free plan is not a trial — it stays free, no credit card required, and gives every student real practice in every domain plus your first full-length test. Pro takes you all the way to test day with the complete 1,265+ question bank, every practice test, your full study plan, and the mistake log to learn from every error — for less than the cost of a single tutoring session.
For teachers and school counselors, our For Schools program makes it easy to bring Grind1600 to your classroom. Give your students access to structured, adaptive SAT prep that supplements your existing curriculum — at no cost to your school or district.
