What exciting times. DS's application year was such an intense rollercoaster, it really takes it out of them. He applied from a good but not stellar comp, he was the only one of the 2 or 3 Oxbridge applicants there to get an interview.
He felt his Oxford interview was an utter, utter disaster, and to be honest, by what he said about it, I agreed with him - it sounded like he'd come across as a complete stammering fool (I didn't tell him that of course, but tried to bolster him!) anyway after that we both assumed that was that and got excited about his other offers, then his first choice college came back with an offer in January, much to our surprise.
He was thrilled about his offer for about, ooh, ten minutes, then started to worry about getting his grades, a worry that lasted seven months.
In the end he considerably exceeded the required grades, and is having an absolute whale of a time. So it was worth it, but I think I have a few extra grey hairs in consequence. It's not that I ever thought Oxbridge was the be all and end all - but, when you know they want something so much, by gosh you want them to have it too.
