3.P12—Using apparatus and techniques

Understand how to use the apparatus and techniques appropriate to this specification.

Use .p12—using apparatus and techniques to connect the rule to the data and decision in the question.

This matters because .p12—using apparatus and techniques determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply .p12—using apparatus and techniques to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: .P12—Using apparatus and techniques is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
