Exam Hints:

Read the question, answer the actual question not the one you want to answer, use of technical terms

  • Learn key words for each topic
  • Learn command words (explain, identify, analyse). Do you know what the question is asking you to do?
  • Read the question 3 times using CUBE to highlight important words in the questions Circle the command word, Underline keywords, Block any examples, then Express your answer
  • Check how many marks a question is worth. If, for example, a question is worth 3 marks, be sure to make 3 valid points in your answer
  • Don’t forget to check through your paper after you have completed the questions to ensure that you are happy with your responses
