High School

Master the SAT, ACT & AP —
in fewer questions

Personalized practice that finds your exact learning gaps. Every question is chosen to maximize your improvement.

Exams

Three exams. One learning engine.

How it works

Three steps to mastery.

Step 01

Diagnostic

A 10-question diagnostic finds your weakest skills. No full-length test needed — just precise signal on where you stand.

Step 02

Personalized Practice

Every question adapts to your exact level. Too easy and you waste time. Too hard and you learn nothing. We find the sweet spot.

Step 03

Smart Stopping

Smart stopping tells you when you’ve mastered it. No more guessing whether you’ve practiced enough.

Validated results

Hundreds of students across independent datasets.

Statistically significant improvement. Our personalized approach has been validated on three independent datasets across multiple datasets.
