Each chapter page now identifies what the current topic prepares students for later: algebra, functions, trigonometry, calculus, statistics, proof, modelling or exam synthesis.
The standard lesson pattern is question, pause, student thinking, explanation, practice and feedback. The platform is being shaped around active reasoning rather than passive video watching.
