Hi, I'm Jisoo.
I teach AP, IB and A-Level physics and chemistry, and IGCSE physics, chemistry and biology, to students at international schools. I also give feedback on IB IAs and EEs.
On this site I write up the questions students and parents ask me most: how courses overlap, what order to study in, and what's changed on the exams.
All exam information is checked against official College Board, IBO and Cambridge documents.
