1 chapters live, each a 60-minute lesson built around IB method marks.

How to use these guides

Each chapter is a full lesson: a prerequisite check, a 60-minute flow, three read-aloud script scenes, worked question types, four common errors, homework and an exit check.

Working alongside the DSE line

The same topic appears in the DSE line with identical definitions and calculations; the difference is assessment emphasis, with IB rewarding method and evaluation over drill.
