Frankly, I think Stanford's admissions office doesn't function particularly well. I realize this will sound obnoxious, and I apologize, but they turned my application around in three weeks. There's no excuse for that: my numbers are good, but they're not that good, and there's nothing spectacular about me - no Rhodes Scholarship, no Ph.D., no Nobel Prize - and I'm not a URM, so the only explanation is that it was a screwup on the part of the admissions office.While your modesty is commendable, most people would say your numbers are that good. Congrats on some really great choices.
This doesn't actually help, but unless Stanford does something spectacular at admit weekend I'll tell them 'no' early next week so another deserving student can have my slot.
And to the OP, someone just posted a message saying you can call Stanford's admissions office and they might give you an answer over the phone.
