OP I attended Exeter decades ago when places like CC didn’t exist. All of these years later I remember vividly feeling some of the insecurities and concerns you are expressing while completing my applications. Take a deep breath.
I can’t promise you that you will get in but I can assure you that no one thing will exclude you, your feelings are normal, what you have accomplished so far is impressive and regardless of the admissions outcomes you will go on to great things if you are confident and determined.
@Panko one aspect of an application that AOs at all of these schools try and determine is fit. At PE the Harkness Table is central to the learning experience, and treating one another with mutual respect and encouragement is considered paramount for a productive discussion. OPs humility, vulnerability and willingness to express her/his self would make her/him an asset to a Harkness discussion.
I hope for your benefit that your predisposition to candor at the expense of kindness is not on display in your applications. That sort of false hubris (even if subtle) will lead to disappointment.
Good luck to both of you.
