I'm currently 16 years old and am from the UK and I've just finished what you guys would call the '11th grade'. I'm really interested in applying to some of these top US unis and have found out that there is a much greater emphasis on ECs here than there is in the UK. Could someone please tell me what sort of ECs would be required for some of these elite schools? Would I have to be playing loads of different competitive sports and winning national science competitions? Or is that all just an exaggeration? Currently I just play the piano and violin, and cycle and rock climb in my spare time, neither of which I do competitively. Obviously I still have about a year ahead of me where I can start doing more ECs so could someone please advise me on what sort of stuff I should be looking at?
