I want to ask a question but don't consider me snobbish please.Why are a levels SO EASY? I mean so many students every year take A* and generally so students score so high marks. the success in this examination seem to depend on the practice you have made and they are not ''measuring'' potential of a candidate...that's why I think top UK universities (cambridge, oxford,...) also ask you to give another examination(step , mat) in order to see if you really diserve a place...if you see in other countries the mean score of the final score of final exams is much smaller .for instance my countries mean score for mathematics is 6/20 (that is 30%....)
