Use this module to build one skill at a time, then apply it in a different situation. Read each worked example, explain its steps and attempt the exercises without copying the example. The mixed review is for retrieval now and after a delay.

## Study and feedback

Reading theory is open. Interactive access depends on your account and module access; the AI Tutor requires eligible All-Access membership. Structured checks provide feedback on specific answers. Written explanations and diagrams need comparison with the worked guidance and, where possible, a teacher's feedback. Passing a check is not a prediction of an exam grade.
