Weekly reports showing what they practiced, what improved, and whether they're on track — from middle school PSAT prep through SAT, ACT, and AP exams.
Your dashboard shows what your child practiced, which topics improved, and where they still need help — not just hours logged.
Free tools say "incorrect." We say "they misread the question — and they've done this 5 times before." That's the diagnosis a $150/hr tutor provides.
Every week: what they practiced, what improved, whether they're on track for their target score. Clear answers, not guesswork.
Every day, they get exactly what to work on. No guessing, no wasting time on topics they've already nailed.
No ads, no social media distractions. Just focused practice that gets smarter every session.
Every session builds on the last. After a few weeks, the system knows your child's patterns so well it can predict where they'll struggle next.
Building strong foundations early makes a real difference. Our PSAT and Foundations courses help younger students develop the skills they need years before the SAT.
For 8th-10th graders. Build the same skills tested on the SAT with age-appropriate content and pacing. Track readiness for high school exams.
For 6th-8th graders. Core ELA and Math skill building aligned with state standards. Identify and close gaps before they compound in high school.
"I don't know if my child is actually studying"
Your dashboard shows exactly when they practice, what they worked on, and their specific mistake patterns — not just time logged. Weekly email reports keep you in the loop.
"Private tutoring is too expensive"
A good tutor costs $150/hour. Mastery OS gives the same level of diagnosis — what went wrong and why — for $29/month. And it never forgets what your child worked on last week.
"I can't help them with SAT prep"
You don't need to be an SAT expert. The system handles the teaching — it figures out what your child needs to work on and gives them the right questions. You just check the weekly report.
"They don't know what to study"
Every day, they get exactly what to work on — no guessing, no wasting time on stuff they already know. Every question targets the skills that will move their score the most.
Here's how Mastery OS compares to the alternatives.
Great diagnosis, but forgets what your child worked on last week. Doesn't scale.
Same-level diagnosis, remembers everything, daily personalized practice, weekly parent reports.
Good content, but no direction. Doesn't know what your child needs to work on or why they're getting things wrong.
Every week, you'll receive a summary including time spent, skills improved, error patterns detected, and how much more efficient personalized practice was vs random.
A professional PDF report with your child's score prediction, skill gaps, error patterns, and a personalized study plan.
Know which colleges are in reach based on your child's current scores and trajectory.
