ignore cowjumping OP
Well yes, go ahead and ignore an academic with 30 years' experience!
@Fazackerley actually, I wasn't thinking about the OP's DS's A level grades. Predicted at BB is fine. I teach in a top-rated Russell Group university department - we're regularly in the top 3 in all the league tables - we take BTECs and mature students - we all take AAA students - we want to get a good fit first & foremost. So I'm not fixated on A level grades.
What I am concerned about is appropriate mindset for university. I was responding to the OP's description of her DS's situation [quote]: DSs failure is frankly down to sheer laziness and then later confirming he's a gamer.
My concern - and thus my advice - was based on this information. I teach undergrads and I know that they need to be not lazy and that distraction via an occupation such as gaming (potentially so addictive) can be really damaging. Undergrads need to be able to be self-starting, organised, and committed.
Even as an academic, totally committed to the wonders & power of education, I do think that we emphasise going to university far too much to the detriment of other kinds of education. It doesn't suit all young people.
And this boy might need a few years to mature.
Or the low mocks grades might give him a wake up call, and he'll pull his finger out and learn how to work effectively and productively, and look forward to much much more of the same at university.
