- Your child asks in English. The teacher answers in Chinese. The interpreter speaks English back — in a few seconds.
- We teach to the College Board course description. No extra tricks that are not on the exam.
- Every session is recorded. You can watch from the same link.
The point most students did not earn
In 2025, AP Calculus BC free-response question 6 asked for the interval of convergence of a Taylor series.
The scoring point for analyzing both endpoints and writing the correct interval averaged 0.14 out of 1.
That figure is from the College Board Chief Reader Report (Question BC6, point P5).
The clip above is a class on that point.
How it works
- 1. Saturday morning, U.S. Eastern (evening in the teacher’s time zone).
- 2. Your child joins on a computer with a headset. You may join muted.
- 3. Teaching is in Chinese. Live speech translation stays on. Bilingual captions stay on.
- 4. The first class is free. If it is a bad fit, stop. You will not be billed unless you book a paid session after that.
