Every video walks through one syllabus topic from the start: the idea, the working, and the exam-style examples — narrated in clear English, at the level the notes are written for.
Subtitles are burned in, in English and Simplified Chinese together, so a difficult sentence can be read while it is heard. Difficult terms carry a small Chinese gloss on screen.
Each video is chaptered. Use the chapter list to jump to the part you need, and the notes and lessons linked beside it to practise afterwards.
