My name is Vivian Robert. I come from Switzerland. I worked with the Swiss curriculum, the IB curriculum and the American curriculum. I’ve taught high school math in three different schools:

- Lycée Jean-Piaget, Switzerland
- American School of Abu Dhabi, United Arab Emirates
- Korea International School, Korea

Some of my screencasts can be found here for AP Calculus AB and Intro to Proofs.

AP Calculus AB: (a) Theory for volumes units

(b) FRQ practice for the AP Calculus AB exam

(c) Textbook exercises worked solutions for harder exercises in all sections

Intro to Proofs: (a) Theory for logic unit

(b) A few additional sections of theory (cardinality of infinite sets…)
