Can essays and rec letters make the difference?

I applied to UChicago ED, but I have a very unusual profile GPA and SAT wise.
I wrote a very strong personal statement and uncommon essay.
I also have a very strong counselor recommendations and three teacher recommendations.
Can good essays and letters be decisive? I know Chicago has the reputation of being very ‘holistic’.

Yes? Maybe? No one really knows for sure. Go read a book or something, stressing about your application you already sent in is unhealthy.

Fair, lol
