Every student is different.
Their SAT prep should be too.We built the tutors that understand your child.
OC Study captures what your child actually knows and builds an SAT study plan that's exclusively theirs. All the detection and fine-tuning happens quietly behind the scenes; all your child sees is a clear next step. It's a complete way to prep for the SAT on their own, and the best support system for any class or tutor they already have.
OC Study turns a focused SAT diagnostic into a personalized daily study plan, supported by six AI tutors and clear progress updates for students and families.

Most tutoring hands every student the same plan, delivered one-size-fits-all.
Ours starts from what your child already knows, adjusting through constant practice to teach at the level that fits them.
I · Building an independent learning profile
It starts with 50 questions, beginning the system's assessment of how your child learns.
A diagnostic of about 70 minutes eases your child in and sketches a first learning profile across every SAT subject: what looks solid, what looks shaky, what's missing. No system can fully understand a student's true level from one test. Not even a professional AI tutor.
Understanding your child's level deepens through daily practice guided by the plan, and every AI tutor interaction feeds in over 100+ signals (speed, hesitation, error type, recovery, and more). Their profile recalibrates continuously as they progress. No need to stop and retest.
II · Building the plan
A clear study assignment a day. Never the same twice.
The plan updates based on more than just answers: your child's patterns, pacing, and work ethic all factor in. Every time they log in, they find a study plan built specifically for them.
Some students sprint; some need three passes at a topic. The plan always revolves around what the student needs.
III · Your child's progress, made visible
Parents always want to know if it's working.
Parents get their own independent account. Once linked to your child's account, you can check their learning progress anytime, with a detailed breakdown of where they stand right now.

The demo
A real session, replayed.
The chat is the lesson, replayed from a real session and sped up for this preview. The panel beside it is the system's read of the student, translated into plain language. The full analysis is far deeper and more complex.
Sessions are shown with our students' permission, and names are changed to protect their privacy.

While your child isn't studying,
the tutor team is analyzing and planning practice around the clock.
Spaced review
Missed questions come back for review, a few days later.
Previously missed questions are precisely timed to resurface right before the memory fades. Ten minutes of review a day, chosen by the system, never wasted on what's already mastered.
Mistake journal
Every error becomes curriculum
Wrong answers are captured and categorized automatically as a careless slip, a concept gap, or time pressure. Each category gets a different fix.
Mock exam
Before test day, plan ahead.
Real timing, real module structure, real score estimates. By the actual exam, the format is thoroughly familiar. A strong score is no accident.
Momentum
Consistency, made easy
Daily streaks and small rewards keep the habit alive, because fifteen focused minutes every day beats a panicked weekend, every time.
The quiet advantage
OC Study is an "unfair" advantage, earned fairly.
OC Study's learning efficiency puts your child ahead of students prepping without it: a team of tutors that never rests, a plan adjusted every night from their analysis, and a review queue that remembers what everyone else overlooks. In the end, it's by learning and practicing with OC Study that your child reaches the goals they set.
The final sprint, done right.
The same prep before test day.
A different result.
How much of that effort actually pays off comes down to the details. However your child spends this final stretch, in a class, with a tutor, or on their own, a personalized system behind them gives them the edge to hit their best score.
Illustrative eight-week trajectories for a student starting near 1220. Every student's curve is their own; the diagnostic draws yours.
OC Study is a complete prep system on its own: plan, practice, tests, and tutors all working toward the same goal. For students who already have a class or tutor, it becomes the best practice support between sessions. Either way, every second of practice with OC Study lands exactly where your child's learning needs it most.

A letter to parents
Dear parents: however your child preps today, you've probably felt the same quiet worry. Hours go in, and you can't quite see where they land. Not because anyone is failing, but because no one can watch a student's every answer by hand.
That's the one thing our tutors are built to do. They measure what your child actually knows, one skill at a time. They rebuild the plan on the go, from your child's own answers, patterns, and work ethic. They bring back every miss until it's beaten. And they put all of it where you can see it, plain and clear.
With respect for what your child could be,

What parents truly
want to know.
"Is this a class, or a replacement for one?"
Neither, exactly. OC Study is a personalized, AI-driven way to prep: a study plan built from your child's own learning profile, practice completed from that plan, full-length tests, and interaction with tutors along the way. Many students use it as their complete prep; others use it alongside a class or tutor as the practice layer between sessions, and both work.
Complete on its own, or a supplement to any instruction.
"We already have a tutor or a class."
Then keep what's working. OC Study fills the part no session can cover. Designing coaching content, sharply analyzing your child's learning needs, and precisely arranging what they study.
Personalized teaching, taken to its fullest.
"Can you actually trust an AI-driven teaching program?"
AI's greatest strengths are raw computing speed and near-limitless memory. When it comes to absorbing specialized knowledge, a single day of AI processing can outpace ten years of human study, and its logic and analysis outperform ours too. OC Study lets you judge it the most honest and most professional way: real-time logic analysis, study plan design.
9,000+ questions in the bank. Each one verified by an AI tutor.
"How do we know how our child is doing right now?"
Parents get their own independent account. Once you log in, you can see your child's learning progress at a glance: time studied, skills improved, score trends, what's gotten better, what's next, and whether the pace fits the test date.
Track your child's learning status anytime, with timely reminders.
