<p>1) No way of telling for sure but Stanford seems to not put as much weight into SATs as other top schools. I think your chances (and for any international, no matter how good their scores are) would be better if you were applying RD. Stanford was always my top choice, but SCEA is a self-selecting applicant pool (AKA much harder for me), so I chose to apply RD and I got in.
2) This is debatable. Do not attach a run-of-the-mill resume that you would send in for your job. What I did was attach an extra sheet explaining my duties and a bit more about my ECs, since they’re not traditional ones. Be careful about attaching a resume: keep it to one page, don’t repeat anything you already put on your app, and only include important things.</p>
