Your child's own
world‑class biology tutor

Aristotle's AP Biology course maps 205 skills to all eight units of the College Board framework: Chemistry of Life, Cells, Cellular Energetics, Cell Communication and the Cell Cycle, Heredity, Gene Expression and Regulation, Natural Selection, and Ecology. 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.

Aristotle works unit by unit to find your child's weak spots and focus there. Because every one of the 205 skills is tracked, the tutor can tell the difference between a topic your child has mastered and one they only half understand, then spend session time on the gaps that will cost points. Your child can review a single unit before a test or run the whole framework before the May exam, practicing the reasoning the free-response questions demand.

AP Biology moves faster, goes deeper into molecular detail, and is graded against the College Board's framework rather than a general standard. This course tracks 205 skills, compared with 120 in general high school Biology, and emphasizes the data analysis and experimental-design reasoning the AP exam rewards. Aristotle tunes every session to that exam standard instead of a general biology class.

Your child talks through problems out loud with Aristotle on a shared whiteboard, whether that is diagramming a signal transduction pathway, working a chi-square problem, or interpreting experimental data like a free-response question. 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.

Science tutors typically charge $50 to $90 an hour, which comes to $600 to $1,080 a month at three hours a week, and AP-level tutors usually add a 20 to 40 percent premium on top of that. 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 it themselves. It also carries the learning process across sessions, remembering which 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 Biology 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. AP Biology stacks concepts quickly, so a shaky grasp of cellular energetics or gene expression can quietly undermine everything after it. Each of the 205 skills is linked to its prerequisites, so Aristotle traces a current struggle back 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 whole year over.
