What parents are telling us
“My son told me yesterday that we should cancel his human tutor, Aristotle is doing a better job. The human tutor was $250/hour.”
“Sam got an A+. So it def worked!!!”
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.

FAQ
Common questions about online AP Precalculus tutoring
Aristotle's AP Precalculus course maps 303 skills to the four units of the College Board framework: Polynomial and Rational Functions, Exponential and Logarithmic Functions, Trigonometric and Polar Functions, and Functions Involving Parameters, Vectors, and Matrices. Every skill is tied to the framework and linked to its prerequisites, so the tutor always knows which part of the course your child has mastered and what still needs work.
AP Precalculus is a College Board course with a standardized May exam, while regular precalculus varies from school to school. The AP course is built around modeling: students construct functions from data and real contexts, then defend their reasoning across graphs, tables, equations, and words, which is exactly what the free-response questions score. Aristotle's AP course follows that framework skill by skill, so sessions practice the reasoning the exam rewards, not just the procedures a typical class drills.
Aristotle reviews unit by unit to find weak spots and spends time where the exam puts points. Polynomial and Rational Functions carries 30 to 40 percent of the score and Trigonometric and Polar Functions 30 to 35 percent, while Unit 4 is not assessed on the exam at all, so review targets Units 1 through 3. Because all 303 skills are tracked, the tutor knows the difference between mastered and half understood, and drills the gaps that would cost points in May.
Yes, and the course is designed for exactly that. The College Board built AP Precalculus around rates of change, function behavior, and moving between representations, because those are the ideas calculus assumes on day one. Aristotle teaches for that fluency rather than memorized procedures. Unit 4, Functions Involving Parameters, Vectors, and Matrices, is not on the AP exam, but it sets up the parametric and vector thinking your child will meet in calculus and physics, and Aristotle covers it too.
Your child talks through problems out loud with Aristotle on a shared whiteboard, whether that is modeling a Ferris wheel with a sinusoidal function, solving an exponential equation with logarithms, or finding the asymptotes of a rational function. 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, available 24/7, the night before a unit test or during homework.
Math tutors at this level charge $45 to $75 an hour, and AP tutoring often adds a 20 to 40 percent premium, which puts three hours a week at $540 a month or more. 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 AP tutors do: it asks your child to explain their reasoning, finds the misconception underneath a wrong answer, and guides them with questions until they can work the problem themselves. It also carries the learning process across sessions, remembering which of the four units your child has mastered and planning what to review next, like a tutor who never forgets.
Yes. Parents get a summary after every session, and the parent dashboard shows which AP Precalculus units your child has mastered and where they are stuck. Sessions are reviewed, and every tutor response is checked before it reaches your child.
Yes. Most AP Precalculus struggles trace back to earlier gaps, often factoring, exponent rules, or the algebra underneath function transformations, and the course moves too fast to catch up by rereading notes. Each of the 303 skills is linked to its prerequisites, so Aristotle traces a wrong answer to the exact earlier skill that is missing and rebuilds from there, instead of repeating the same lesson louder. Your child can catch up mid-course without starting the year over.
