Hmm I haven't received a rejection or invite. Feel like I will be rejected soon.
4.0 high school (with 20 ap classes)
4.0 college
1600/1600 sat 35 act
Started my own nonprofit that has grown to 500 members, have a business that is profitable, president of academic honor society, interned at Google freshman summer and at CSIS, a prominent policy think tank in washington DC this past fall. Also have 2 science publications as first author.
I thought I had a really solid resume with an amazing flexmed plan with good essays. Can't say for sure what my letters were like but I have a good relationship with all of them as research mentors. They all think highly of me and are proud of my accomplishments (I think)!
I truly don't know what I could have done better even if I had a chance to start my life over. Objectively speaking without trying to be bragging, I really thought I had a chance to be picked.
So to answer your question
@Platinumabi, I have no freaking clue.
