Boost your SAT score. With adaptive prep and AI.
Adaptive practice tests, AI explanations for every wrong answer, and skill-level analytics that show you exactly where to focus.
How it works
Question 7 of 22
Which expression is equivalent to 3x² + 6x + 3?
Take a practice test
Adaptive format mirrors the real Digital SAT — two modules per section, difficulty routing after Module 1.
Your answer
Choice B
Correct
Choice A
Factor out 3 first: 3(x²+2x+1). Now x²+2x+1 is a perfect square — it equals (x+1)². Choice B expands to 9x²+6x+1, which is different.
See exactly what went wrong
Every question gets a plain-English AI explanation so you learn the concept, not just the answer.

Skill-targeted drills and spaced-repetition flashcards keep you working on what matters most.
Why it works
Built for how you actually learn.
Most prep tools give you more practice. We give you the right practice — targeted, explained, and tracked against your specific gaps.
Real Digital SAT format
Full two-module adaptive structure per section — same difficulty routing as the actual test. Not simplified, not old-format.
Explanations that teach
Every wrong answer gets a breakdown of the reasoning — not just "the correct answer is C." You learn why C is wrong and why A is right.
Skill-level insight
Not "Math: 72%." You see Inference: 52%, Geometry: 61%, Systems of Equations: 68% — so you know exactly where points are going.
A plan that adjusts
Your weakest skills feed a daily study schedule automatically. No guessing what to practice next — just show up and work the plan.
Analytics
Know your weak spots before test day.
See your accuracy broken down by skill, the difficulty bands where you're losing the most points, and exactly how long you're spending on each question type — so you stop studying what you already know.

AI Tutor
Ask why, not just what.
After any question you missed, open the built-in tutor and ask anything — why your answer was wrong, how to spot the pattern next time, or what concept you're missing. It knows the exact question and your reasoning.
- ✓Explains the reasoning, not just the answer key
- ✓Remembers your specific wrong choice and why it looked right
- ✓Breaks down the underlying concept so it sticks
From students
“I'd been grinding vocab flashcards for months thinking that was my weakness. The analytics showed my inference accuracy was at 52% — that was the actual problem. I wouldn't have found that on my own.”
Priya R.
Junior, retaking in spring
“The explanations don't just say 'because the passage says X.' They walk through the actual reasoning. That's the difference between knowing an answer and understanding why, and it's the thing that finally made concepts stick.”
Marcus T.
First-generation college applicant
“I kept running out of time on Math Module 2. Turns out I was averaging four minutes on geometry questions and ninety seconds on everything else. Once I saw the breakdown, I knew exactly where to focus.”
