I too am reeling at @Frankl four! It must be so difficult to know how to handle it - obviously easy if all four get in, but hard in any other combo (especially three I guess).
Going back to my laid-back son, I guess it's good if not everyone at Oxbridge is a crazily academic, accomplished person. Not that he's got in but I presume that were he to squeeze in, there would be plenty of others like him. I remembered a funny v true thing Hugo Rifkind wrote that I'll copy and paste:
Going up to Oxbridge hits you in one of two ways. Some people go into shock. Back at their sixth-form college in Arsehampton, Bottomshire, they were the cleverest and most interesting person around. Here, though, they’re average. Or worse, bland. Sure, they’re quite good on Shakespeare’s use of garden imagery in Hamlet and are grade seven at the violin, but that bloke in the next room? He’s trilingual. He’s dating a Cambodian princess. He has read Thucydides in Greek, spent his gap year interning for Deutsche Bank and used to be secretary-general of the Model UN.
[Then he goes onto say later...]
The opposite approach, Oxbridgewise, is to feel like you’ve blagged it and experience an overwhelming sense of relief. That was me. Emmanuel College, 1995. “I’m here!” I said to myself. “I can do basically nothing for the next three years, and I will still always be a person who got into Cambridge.”
