Basically, A-levels, being no longer as important to employers on its own, only serve as a stepping stone before university. Each A-level is designed to test the student so that he/she can show their true potential at understanding and retaining knowledge (and thereby guiding a University towards their true ability). If a subject needs no revision, and the majority can just pick it up as it goes along (which some of you admit to) then please tell me wheres the challenge? Can anyone compare an A grade to be equal to an A in physics?
It is not well received because although many bright students take it, this lack of effort needed to do well makes it near impossible to distinguish between the good candidates, and the excellent ones.
