The only comment I would make is that a reader / senior lecturer and also a senior professor who taught me History at my Red Brick uni left to go to Oxford.
So you are being possibly taught by the same people. However, I had the benefit of having smaller classes or seminars at my college. Both were/ are leading experts in their field. In fact as you walk into the History section at Waterstones or Foyles many of the books on their topics are written by them.
One also had a well publicised ongoing feud with another Historian much aired in the Times / Telegraph whose name rhymes with Riggs.
My own regret is that I was too emotional anxious and getting over various boys to appreciate the peals of wisdom taught at university. I suffer terribly with anxiety and dyspraxia so struggled to write in those days before laptops.
I never went below an A minus or AB ( border line 1st) for all the essays I wrote in second and third year but ended up with a 2:2 because I freaked out with exams. The famous professor called me in and asked what could be done about it all as I got a first in one exam and then had a panic attack and got a third in another. That was my general pattern. Neck in those days there were no mitigating factors, extra time or quiet rooms.
That’s something that no one has mentioned and that is do exams test anything but nerves? Had I been continuously assessed at school, university and law school I would have been right up the top. So for many reason I don’t but the whole Oxford hype as a professor from my university marked my essay as firsts and then went to Oxford and marked people’s essays there as firsts etc.
My point being the people teaching at Oxford have probably just come from down the road in UCL or Kings etc. I doubt that the quality of reaching is all that much better.
Clearly, my advice would be go to Oxford as it’s well known around the World and opens doors but I don’t buy the concept of better teaching.
