But of course she will attend Yale!!
Well, for what it is worth, I got something similar 30 years ago, but not a phone call though.
I actually got a personal letter at the end of January from an admissions officer of same class of school (HYP) telling me he liked my application and that I would be accepted. It was not an likely letter either. It was a simple I like your application and we will accept you. And signed personally by the admissions officer.
It was a weirdly personal letter and he clearly had ability to just call the shot three weeks after receiving my application.
Congrats! Cambridge and New Haven are battling it out for you! Can’t beat that.
Congrats!
