From our families

What parents are telling us

Aristotle is so impressive. It explained a math problem to my daughter that ChatGPT couldn't figure out.

Akshay

My son told me yesterday that we should cancel his human tutor, Aristotle is doing a better job. The human tutor was $250/hour.

Kim

Why families switch

Everything an hourly tutor can't be

On demand, 24/7

No scheduling, no weekly slot. Help is there during homework at 9pm and the morning before the test.

A fraction of the cost

Unlimited sessions on a flat plan instead of paying a human tutor by the hour.

Truly personalized

Aristotle tracks every skill your child has mastered and teaches at their exact frontier: never too easy, never too far ahead.

Driven by science

How Aristotle works

Built for the digital SAT

Prep that follows the real test

The official blueprint

SAT Math skills are organized around the College Board's four official domains, and Reading and Writing around its question types, so practice matches the real test.

Your child's strengths and gaps

Aristotle tracks every skill across both sections and spends time where the points actually are, instead of drilling what your child already knows.

Your target score

Working toward a specific score or an application deadline? Aristotle builds the path backwards from test day.

FAQ

Common questions about online SAT tutoring

Both sections. SAT Math is organized around the College Board's four official domains: Algebra, Advanced Math, Problem-Solving and Data Analysis, and Geometry and Trigonometry. Reading and Writing covers Information and Ideas, Craft and Structure, Expression of Ideas, and Standard English Conventions. Every skill is individually tracked, so the tutor always knows what your child has mastered and where the next points are.

Yes. The curriculum follows the current digital SAT: each section is scored 200 to 800, runs as two modules, and the second module adapts to how your child did on the first. Practice matches the pacing of the real test, about a minute and a half per math question.

Your child works through real practice problems out loud with Aristotle on a shared whiteboard. Aristotle asks questions, listens to their reasoning, and guides them to the answer instead of handing it over. Sessions start whenever your child is ready, with no scheduling: a quick session after homework, or a longer review the weekend before test day.

General SAT prep tutors charge $60 to $120 an hour and SAT specialists charge $100 to $200, which comes to $720 to $2,400 a month at three hours a week. In major cities, established test-prep tutors run $150 to $300 an hour. Aristotle costs $299 a month for unlimited sessions across every subject, or $49 for a single session.

Chatbots hand your child the answer and forget them when the chat ends. Aristotle teaches the way expert tutors do: it asks your child to explain their thinking, finds the misconception underneath a wrong answer, and guides them with questions until they can solve it themselves. It also tracks every SAT skill across sessions and plans what to practice next, like a tutor who never forgets.

Yes. Parents get a summary after every session, and the parent dashboard shows which skills your child has mastered and where they are stuck. Sessions are reviewed, and every tutor response is checked before it reaches your child.

That is where Aristotle is strongest. Every SAT skill is linked to its prerequisites, so when a practice problem exposes a gap, Aristotle traces it back to the underlying algebra skill and rebuilds from there. Points come faster from fixing the foundation than from drilling the same question type again.

Whenever they start, Aristotle meets them where they are. Many families begin a few months before the first test date, but a shorter runway also works: sessions are unlimited and on demand, so your child can practice every day without scheduling or per-hour costs.
