They were prepared for use by markers. All markers are required to attend a rigorous standardisation meeting to ensure that the guidelines are consistently interpreted and applied in the marking of candidates' work. • Note that learners who provide an alternate correct solution to that given as example of a solution in the marking guidelines will be given full credit for the relevant solution, unless the specific instructions in the paper was not followed or the requirements of the question was not met • Annexures A, B, C and D (pages 3 to 12) include the marking grid for each question. • Annexures E, F, G and H (pages 13 to 27) contain examples of solutions for Questions 1 to 4 in programming code. • Copies of Annexures A, B, C, D and the summary for the marks of the learner (pages 3 to 12) should be made for each learner and completed during the marking session.
