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

In a quiz there are ten questions. Each correct answer gains five points. Each wrong answer loses two points. (a) Liz gave ten correct answers. How many points did she get altogether? 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)

( a) 50 B1 - Marks awarded independent of method (b) subtracted from their 35 M1 – Method mark 29 A1 - Accuracy marks are awarded when following on from a correct method 35 M1 – Method mark (c) 9 questions right or 1 question wrong or 45 right 2 wrong B1 45 correct 1 wrong or 9 correct 2 wrong or 45 and 2 seen B2 - Marks awarded independent of method [6]

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 = 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”. Common Mistakes – what did the examiners say?
