EvilTwins: 'no-one gives a shit what your GCSEs are once you get to the next level', I am afraid plenty of universities do give a shit. Perhaps someone ought to alert them to that fact.
One of the main problems of children from poor backgrounds not getting into top universities is because they are being actively encouraged to take unacceptable (by the universities) GCSES or diplomas.
It is not snobbery or backward thinking not to collude in the hypocrisy that is rife in the education system at the moment.
Why on earth do you think the universities are dominated by the private sector? Because those children are all much more clever?
Or because those schools have got the measure of which GCSEs are acceptable by the top universities. They have got it down to a tee and equally clever children from schools where they are encouraged to take different subjects are losing out on the places.
Whilst I accept that certainly not everyone is interested in applying to a redbrick/Russell Group/Oxbridge, if they are then, unfortunately, they need to know what is or is not acceptable.
The choices we made years ago are not relevant today, after all when I was at school very few pupils got 3 As at A level. Now, so many more do and the most academic universities do look at GCSE grades, as well as setting their own entrance tests.
Diplomas etc may well be being bandied about as being equivalent to 4 As at GCSE or whatever, but until someone can convince the university admissions departments (for oversubscribed academic courses) that they are, then it's all a bit of a mess, to say the least and parents/pupils are being fooled.
(It's interesting that a Business Studies teacher herself wouldn't recommend the subject to the higher level pupils.... why on earth would that be?)
