An aside, a disclosure, if you like.
Both my DSs have BTECs. The older messed up his GCSEs due to immaturity (by which I mean, AABBBBBBCC). He went on to a well regarded sixth form (AS level Maths, Physics, Economics and Geog.)
That went the same way, at Y12, so we pulled him out in order to do a 3 A level equivalent BTEC in Computing. Which had 4 exams (in 13 modules) as the govt was still smarting from the public anger with the modular, no exam approach where DC resat, and resat the modules they weren't happy with....
He got D star, D star, D, in that BTEC.
He's now at an ex-Poly doing Computing; all well.
But, what he's doing doesn't belong in uni! It's a technical qualification any Poly or Tech could have provided, back in the day! Yes, he grew up and worked hard in his modules for his BTEC, but he never faced the sheep/goats of A levels. Those on his course who did, got C/D,even E. (And it showed).
He'd've never have gone to a RG even with his BTEC triumph.
His is a middle ranking uni. He will get a reasonably paid job out of it. But how many people are being sold that pup? A year to go from 'no GCSEs' to ready to pass a value for money, meaningful degree?
