I briefly taught law at a very rubbish university. The students were with one exception lazy and useless, and their work was appalling. Many openly copied and pasted from the internet. I was pressured by the Head of the Department to push marks up. In one assessment, there was only one student who, applying the marking scheme, warranted a First, and none who warranted a 2,1. The rest were Desmonds, Richards, and outright fails. But the marking scheme went into the bin during moderation, and the whole lot got 2.1 and 2.2s, mostly underserved.
Maybe I am a bad teacher, but I observe that every single one of my many pupils at the Bar has taken Silk (two of them are now the joint Heads of Blackstone Chambers, the number one set of barristers' chambers in the Common Law World).
The one good student was a Muslim woman who wore a hijab. She had obtained a place to read law at Cambridge but her family would not let her go there. She was bored and frustrated. At Cambridge, she might have got a 2.1, and maybe even a First. She was on for a First at the duff university. I urged her to do postgrad at UCL, KCL, or the LSE, and to tell her parents that she could commute daily.
I recently met online a bloke who teaches a variant of Grievance Studies at a very dire university. He has a BA, an MA, and a PhD from that university, now has a Chair, and has spent his whole career writing utter nonsense, some of which is published in laughable journals. He can barely write a comprehensible sentence. Oh well, it's a job.
Oxford, Cambridge, and a number of other UK universities maintain and defend real scholarship. They set exacting standards for their undergraduates. They are not really in the same industry as the degree mills.
