Functional Question Foundation (Number 8) For the week beginning ….

Answer ................................................. (1) (b) Glen gave seven correct answers and three wrong answers. How many points did he get altogether? Answer ................................................. (3) (c) Iqbal answered all ten questions. Explain how Iqbal could get 43 points altogether. (2) (Total 6 marks)

Common Mistakes – what did the examiners say? Most candidates indicated that they were using the correct method in part (b). However, arithmetic slips were extremely common. The most frequent errors in method were 35 + 6 = 41, 10 × 5 – 6 = 44 and 7 × 5 – 3 = 32. In part (c) many candidates scored full marks. Some were confused over the 2 points lost for 1 wrong answer, so 9 right, 2 wrong and 8 right, 2 wrong were seen frequently. Weaker candidates worked back from a full score of 50 stating that were wrong. A few candidates were very vague, saying that “some were incorrect”.
