CAS practice: The testing interface is part of preparation
A candidate can understand a method and still struggle with an unfamiliar item type or spreadsheet interaction. Practise the official testing resources appropriate to your sitting. General spreadsheet fluency does not establish which functions or actions are available in the exam.
Worked example or practice scenario
For an original drill, present the same development calculation as a written formula, a short table and a spreadsheet task. Check that the basis and timing remain consistent in each format. Then separately practise navigating the official demonstration interface.

Keep conceptual mistakes distinct from interface mistakes. Consult the current testing guide and content outline. Do not infer permissions or submission procedures from a screenshot of an old exam environment.
