One of the biggest problems I find with the students I tutor is they cannot understand what the question is asking them to do. Once I explain it they are often able to do the calculation fairly easily. This is an example from an AQA paper I was doing with a student yesterday. k = n^2 + 9n + 1 Mo says, “k will be a prime number for all integer values of n from 1 to 9” Show that Mo is wrong. You must show that your value of k is not prime. [3 marks] What is being asked is actually very simple, but he simply couldn't understand what was required until I explained it. I wonder if the questions are tested on typical year 10 or 11 pupils to see if they can understand them.
