CalamitouslyWrong I can't see why, though.
I didn't read the Aeneid in its entirety for my Latin O or A Levels, but I was able to understand that it was a reasonable expectation when I trotted off to Uni to read Classics.
You progress from spending 2-3 hours a week on a GCSE subject, to rather more for A level, to full time as an undergrad, surely?
Given that the G in GCSE stands for General, you're teaching an awful lot of people who will do perfectly well studying a range of Eng Lit or whatever, but will have absolutely no interest in taking it further; presumably by the time you rock up at University you've picked something to study that you're actually interested in.
