Copyright reserved Please turn over ### Page 2 Information Technology/P1 2 Hlayiso/Mock 2026 NSC – Marking Guidelines GENERAL INFORMATION: • These marking guidelines are to be used as the basis for the marking session. Markers should discuss the guidelines before marking to ensure that they are consistently interpreted and applied. • Learners who provide an alternative correct solution to the one given in the marking guidelines must be given full credit for the relevant solution, unless the specific instructions in the paper were not followed or the requirements of the question were not met. • Annexures A, B, C and D contain the marking grid for each question. • Annexures E, F, G and H contain examples of solutions for QUESTION 1 to QUESTION 4 in programming code. The complete model-solution projects are supplied in the folder memo_p1_solutions. • Copies of Annexures A, B, C and D and the summary of the learner’s marks should be made for each learner and completed during the marking session. • Code that is not executed (e.g. because of syntax errors in another part of the program) must still be marked, but marks are only awarded for statements that are logically correct. • Where a value is displayed in the wrong component or with a minor formatting difference (e.g. a missing space), award the mark for the calculation but not for the display. • Built-in routines that do the work the question asks for (e.g. Ceil, CharInSet) earn NO marks for that part of the question.
