If you have a disability, are from a BAME background, come from a working class background or go through any illness Oxbridge is not the place for you.
I had the most amazing support through my health issues
I was able to defer my finals to have spinal surgery
I got priority accommodation in college in a building specially designed for accessibility, with a disabled friendly wetroom opposite (I'm not disabled but my mobility wasn't spectacular, and there were no other students with greater need at the time)
The same building was also adapted with a special fire alarm for deaf students
I had back supports kept for me at the Bodleian library, history faculty and exam schools building where lectures were held
I did my exams in college with my own invigilator with extra time
A friend with severe dyslexia got funds so he could photocopy all his library books and highlight them as he wasn't able to make notes. He did his exams on a computer and was given extra time. He got a first.
I don't have personal experience of more life limiting health issues, but I felt nothing but supported. The pastoral care of the college system was amazing, as I had my personal tutor who looked out for my welfare throughout my time there. Every student had a personal tutor for pastoral care - someone who knew you and your situation, you weren't an anonymous cog in a large machine
