COMPUTER APPLICATIONS TECHNOLOGY
PAPER 2
GRADE 12 
NSC EXAMS
PAST PAPERS AND MEMOS
NOVEMBER 2018

SUGGESTIONS AND RECOMMENDATIONS TO MARKERS  

  • Revisit the questions and the marking guidelines frequently during the marking  session.  
  • It is advisable to read the question frequently (and re-read) together with the  candidate's response to check that it correlates, so that you are not misled by the  candidate's statements/answers. 
  • Be careful not to focus on keywords or general statements, but rather read the entire  answer. If in doubt, read the entire answer and then the question paper and marking  guidelines. Ask yourself or your senior marker if the response could ΄fit΄ into the  marking guidelines before allocating the correct marks to the candidate. For example,  the marking guidelines state 'cheap' and the learner responds with 'less expensive'. 
  • Beware of overlapping answers to a specific question. In general, one mark is  awarded per fact.
