Well, the test did not specify that a particular method should be used. It just asked for the student to calculate the answer and show the working (which he did). He knows the "correct" way of doing it too, and could have done it if instructed to. He has other ridiculous examples, e.g. a question that asked what reason might explain why people were smoking less. He gave a perfectly good answer (better awareness of the risks), it just wasn't the "approved" fact they were looking for. It was somewhat like this when I was at school, but it's much worse now. No thought, even correct answers with working not accepted. Sometimes you just have to guess what the approved fact you are supposed to regurgitate is.
