You already know, you are set for spring weeks.I've already posted in the CV thread, but as I'm just preparing to send off the first applications proper now I'd just like a quick evaluation of my prospects. I'm looking for a spring week.
PPE at Oxford. A*A*AA at A-level (plus an A* in EPQ). Two week internship in 2013 at a bulge bracket bank's investment management EM equities desk, although I never had the chance to do much (it was more of an access event for people from families with low income); it was more talks and workshops than actual work. I'm monolingual. My volunteer work consists solely of helping out at a local library throughout last year. My interests are esoteric and not the sort of things you'd put on a CV (tabletop/p&p RPGs, reading excessively, writing, etc). I've yet to start uni to get stuck in to extracurriculars.
I know this is obvious but really now you should just make sure you score well on the tests, get the competency questions in an OK standing, get your CV 100% 'correct' and prepare for your interviews. There's hardly anything you can add to your resume by the time you'll hand in your apps so that it would increase your chances; you have now a very strong profile anyway.
