@CornellReject, I received my rejection letter and it said the same thing, so no, they aren't personalized. I think it's just to try and give some rationale behind the decision.
I applied to CALS, have a 3.93 GPA(currently attend community college), have a number of extracurricular activities including serving on the student council and on number of school committees, a member of PTK, have worked full-time whilst going to school, etc etc etc. I did have a pretty mediocre high school record, but that was nine years ago.
I wasn't sure what to expect when I applied, I really just wanted to apply to one ivy league and was strongly advised to do so by one of my professors, so i'm not really upset by the decision. I thought I had a decent shot though. Still waiting to hear back from USC and UW, but i've been accepted to two other schools so it's all good
Congrats to everyone who got in and good luck to my fellow rejects!
