2 COMPUTER APPLICATIONS TECHNOLOGY P2 (EC/SEPTEMBER 2023) SUGGESTIONS AND RECOMMENDATIONS TO MARKERS • Revisit the questions and the marking guideline frequently during the marking session. • It is advisable to read (and re-read) the question frequently 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 the marking guideline. o Ask yourself if the response could ‘fit’ into the marking guideline before allocating the correct marks to the candidate. o Accept correct answers that are expressed differently, e.g. the marking guideline states 'slow' and the candidate responds with ‘not fast’. • Beware of overlapping answers to a specific question. In general, ONE mark is awarded per fact. • Do not choose answers on the candidate's behalf. Where a question requires a candidate to LIST or NAME: mark the first number of instances required, e.g. the first TWO facts if the candidate presents a list of FIVE facts and only TWO facts were required, even if presented in paragraph format. • Questions requiring longer answers must be regarded as a single unit. Marks can be awarded if correct statements are found anywhere in the paragraph. Copyright reserved Please turn over
