COMPUTER APPLICATIONS TECHNOLOGY PAPER 2
GRADE 12
NOVEMBER 2017
MEMORANDUM
NATIONAL SENIOR CERTIFICATE

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.
