How it works

A personalized plan, with us in your corner

Each student gets a plan and schedule matched to what they're covering in school right now — and we keep them on track and unstuck the whole way. Watch the walkthrough below for how the program runs week to week.

Recorded lessons for every topic

Work through our full library of lessons covering the entire course — start whenever you're ready, including over the summer.

A personalized plan & schedule

Your success coach builds a study plan around what your teen is covering in school right now — with target dates and direct links to each lesson. It's tailored to their class, never one-size-fits-all.

Practice portal

Work AP-style problems by topic. Solve on a built-in whiteboard or just snap a photo of your handwritten work and upload it.

Instant AI feedback + video solutions

Our AI grader — trained on our own rubrics and problem-solving steps — gives immediate feedback on how you worked the problem, plus a video solution. Retry to improve your score and track your progress.

Human review whenever you want it

Not sure you got it right? Request a human review and we'll send a personal video breakdown of your work — usually within 24 hours.

Office hours & community Q&A

Post any question — any topic, any time, evenings and weekends — and we send back a video explanation. Office hours are there when you want to talk it through live.

Why personalized

Built to match your class — not fight it

Unlike AP Physics 1, courses like AP Calculus don't follow one standard order — every school and teacher sequences the units differently. A fixed live lecture schedule would pull your teen out of step with their class. A personalized plan keeps them perfectly in sync.

Follow your teacher's order

Jump to whatever unit your class is on. You're never waiting for a lecture or scrambling to catch up to one.

Go as fast or slow as you need

Breeze through what clicks, slow down on what doesn't — with feedback and video solutions at every step.

Questions

AP Calculus FAQ

How is this different from your AP Physics 1 program?

AP Physics 1 runs live lectures because that course follows a natural order. AP Calculus doesn't — every school sequences the units differently — so instead we build each student a personalized plan: recorded lessons on a schedule matched to their class, a practice portal with instant feedback, human review, and office hours.

Can my teen start over the summer?

Yes. The summer program is $375 and covers self-study access through the summer — and your first month of August classes is included free. School year continues at $375/mo after that.

How does the practice grading work?

Your teen solves problems on a whiteboard or uploads a photo of their work. Our AI grader — trained on our own rubrics and problem-solving steps — gives immediate feedback and a video solution. If they want a human to look, they can request a review and we send a personal video breakdown within about 24 hours.

What if they get stuck or have a school-specific question?

They post it in our online community any time — any topic, evenings and weekends included — and we send back a video explanation. Office hours are available when they'd rather talk it through.

Does it cover both the school class and the AP exam?

Yes — the lessons and practice cover the full course, so it supports their school class all year and prepares them for the AP exam.
