A common mistake the examiners point out: Accuracy: 2 s.f. answers, early rounding and ignored accuracy instructions. What to do instead: Keep full calculator values (store them) until the very last line. Give final answers exactly or to 3 s.f. unless the question says otherwise, and when a given answer has more figures, show your value to more figures than that before rounding.
