While it’s unfortunate that you’re currently waiting on schools, that’s no excuse to be discrediting others’ achievements. :/ You have no idea whether they may have had many parts of their application stand out, like their personal statement or LORs. Or perhaps they aced their interviews and yours were shaky. You don’t and can’t know 100% why they were accepted and you have not been. I really do hope you get into a school and don’t allow this discourage you, but you also shouldn’t drag other people down to make yourself feel better.
