How it works
SAT prep that fits around school and everything else, instead of taking over your evenings.
Day one
One full-length practice test gives you a score estimate and a skill-by-skill breakdown of where your points are going. Your first one is free.
Every day
Two short practice sets a day, on the skills worth the most points.
Through test day
Mastered skills come back for quick reviews just before they'd fade, so what you learn in week one is still there on test day.
Why StudyPlanet
You don’t need thousands of random questions. You need the ones you’re still getting wrong, and StudyPlanet finds them for you.
Once you've shown you know a skill, it drops out of your practice, so every minute goes to points you don't have yet.
Questions get harder as you improve and ease off when a skill needs work, so practice stays productive instead of frustrating.
Each explanation shows the trap behind the most common wrong answer, so you stop making the same mistake twice.
Your plan shows which skills stand between you and your target score, and what to practice today to close the gap.
Full-length adaptive practice tests match the Digital SAT's modules, timing and tools, so the real thing feels familiar.
Set your test date and target score. Your dashboard counts down to test day and keeps each day's practice on the skills that close the gap.
