Just that really. I work in a university but am also a mental health professional, and I'm struggling to see the point of them. They cause a shed-load of stress and angst, but for what...?
I understand that they were introduced to help distinguish between the very able and the exceptional, but how many universities really need to make that distinction? The University that I'm with (think lower tier Russell Group don't tell them I said that, I'm fairly sure it's an instant dismissal offence) is very unlikely to need them for selection purposes, for even our most competitive courses. In fact, the only universities that I can think will make any use of them are Oxbridge, and maybe Imperial and UCL for their most demanding degrees.
Did we really need to upheave the entire system and demand ever higher levels of perfectionism, in the interests of a tiny handful of universities? Or have I missed the point?
