From the team behind our AP Physics 1 results — founded by Allen Tsao (Electrical Engineering, UC Berkeley & Stanford).

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.

A weekly live practice session

The one standing class on the calendar. Your teen works problems on their own whiteboard while an instructor watches live and steps in the moment something goes sideways — feedback on the approach and the setup, not just whether the answer came out right. Come when it fits; nothing is required.

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.

Help with your own class work, three ways

Stuck on tonight's homework? Ask our AI and get a step-by-step breakdown in seconds, built on the same problem-solving steps we teach — not just the answer. Want a person instead? Post the problem any time, evenings and weekends included, and an instructor sends back a video — usually in 2–3 hours, never more than 12. Or bring it to live office hours and talk it through. Three routes, because how fast you need an answer changes which one you want.

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.

One program, everything included

Start with a single month

It's one personalized program to a great AP score, with everything included — no tiers and nothing to upgrade. Whenever you join, your coach builds the plan around where your class actually is.

Currently Enrolling
Start with 30 days.
$375
for 30 days of full program access — the whole personalized program, from the day you enroll
Then you decide at the end of the 30 days whether to continue. What it costs to continue through the AP exam depends on what you actually want out of the program and how you'd like to structure the payments — so Allen works it out with you directly at the end of the 30 days, once you've both seen how it's going.
The full personalized program — recorded lessons on your schedule, the practice portal with instant feedback, human review, the weekly practice session, and office hours. No tiers, nothing to upgrade.
Book a call with Allen

Enrollment is by call only. Allen will tell you honestly whether this is a fit before anyone pays anything — and he’d rather say no than take your money.

✅ Two-week improvement guarantee

You have two weeks to get every dollar back. In that time your coach builds the plan around your actual class, you work real problems, and you get real feedback on them. If it isn't helping, tell us before day 14 and we refund the full $375 — no fees held back. After day 14 the 30 days aren't refundable, and we don't do partial refunds — but continuing is still your call: we email you, and nothing is charged until you say yes. If you have concerns at any point, reach out to Allen directly.

$375 today is the only thing you're committing to — it covers your first 30 days in full. If you decide to continue, Allen sets the price for the rest of the year with you directly, based on what you want out of the program and how you'd like the payments structured.

Waiting doesn't get you a better deal. What it costs you is runway — every month you wait is another month of material to close on your own before the exam.

Every family starts the same way — on a short call. Allen goes through where you actually are and tells you honestly whether this is a fit; if it is, he gets you enrolled on that call.

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. There is one live class on the calendar — a weekly practice session, where your teen works problems with an instructor watching.

Can my teen start any time of year?

Yes — enrollment is rolling. Because the program is personalized, your coach builds the plan around where your class actually is and how much time is left, so there's no cohort to fall behind.

Waiting doesn't get you a better deal — it just buys less program before the exam.

How does payment work?

You pay $375 today, and that covers your first 30 days. At the end of the 30 days we email and ask whether you want to continue — and if you do, Allen works out the cost for the rest of the year with you directly. It depends on what you actually want out of the program and how you'd like the payments structured, so it's a conversation rather than a fixed number on a page. We never charge the card on file without your go-ahead, and only on the schedule you approved.

The first two weeks are fully refundable, in full and with no fees held back — so you can stop inside two weeks and pay nothing at all. After day 14 the 30 days aren't refundable, and we don't do partial refunds. If you have concerns at any point, reach out to Allen directly.

What if the program isn't a fit?

It's no risk to try. In your first two weeks your coach builds your plan, you work real problems, and you get real feedback on them — that's how long it takes to know. If it isn't helping, tell us before day 14 and we refund the full $375. No fees held back, no hoops, no hard feelings.

Can we see a lesson before we commit?

Absolutely — want a free demo? Watch real lessons on our AP Calculus YouTube playlist: AP Calculus.

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.
