I think only a few (less than 5) of the pupils in her school have applied for Oxbridge and noone she was friends with applied to Cambridge, so there's not much of a chance of her being feeling bad comparing herself to friends who have got in - in fact, she's struggled with the fact that she's had her sights on oxbridge. Some 'friends' have been actively dismissive and sneery about it all because it's so far out of their frame of reference. She's ignored all of that and really put the work in, so I would love her to succeed. She hasn't had many failures (if you don't include a lack of a social life outside school) and there were tears at GCSE when she 'only' got an A in Maths. Although, failing her driving test (twice) has given her a bit of experience at that since then!
When she didn't hear about an interview due to an email mess up, she was pragmatic, saying that she liked her next two choices. I hope she can hold on to that if Monday brings no offer.
I haven't told her, but there's a tiny part of me that hopes it's a no. I know that she can be in danger of overworking herself and being unable to rein it in which can lead to stress and the odd meltdown, usually just before exams. GCSE exams (not mocks, 50% of the final exam score) in January the other year, for example, meant Christmas was ruined because it was hard to get her away from her room where she was revising. Cambridge don't rate or take into account Welsh bacc, which is compulsory at her sixth form and which she's in line for at least an A for already. Her other choices do take it into account and would be more wiggle room for getting the grades she needs (AAA for York, AAB for Liverpool).
I shall be glad when Monday is over!
