Examiner Tips and Tricks

When you answer calculation questions, remember:

  • Take care that your figures are easily recognisable

    • In some cases, the number 4 and the number 9 could be confused by the examiner

  • Check the number of decimal places or significant figures required

    • If you only give  your answer to one decimal place rather than two, you will lose a mark, even if your answer is correct
