I have written my Common Application essay on my time volunteering and interning which I found to have revealed a personal challenge. I also mention how this challenge galvanised my interest and how it defines my aspirations. So I think that my Common App essay answers the prompt quite well.
However, as I looked at the UC App essay prompts, I noticed a similarity in that the UCs could be asking me to write similarly:
Describe the world you come from — for example, your family, community or school — and tell us >how your world has shaped your dreams and aspirations<.
Tell us about a personal quality, talent, >accomplishment, contribution or experience that is important to you<. What about this quality or accomplishment makes you proud and how does it relate to the person you are?
So my question is: would it be fine for me to use my Common Application essay (word for word) for the UC App?
