Using a Calculator
What is Using a Calculator?
The disciplined use of a scientific calculator: entering a whole expression with brackets rather than in separate pieces, retaining unrounded values throughout, checking that the angle mode matches the question, and translating the display back into the units and form the context requires. It is a judgement skill rather than a keying skill, and each route's non-calculator paper does not assess it: Paper 1 for Core candidates and Paper 2 for Extended candidates.
