When I sat higher maths (2009) I remember being in class one day, it was when the standard grade exams had happened and our teacher had brought us up the credit papers to have a look at them. Now this was the top class, it was the same teacher and roughly all the same pupils that had been in this class for five years, we get this paper out and I'm sat looking through it, completely unable to answer anything in it. I think there was one question which was just calculating how much money was in a bank account based on the interest on it which was just putting the numbers into a calculator. Everything else may as well have been written in Chinese.
