Extracurricular Essay/ Resume Help

[Guest]

I am preparing my Columbia application and am confused on the extracurricular resume/ essay. I am stuck between preparing an essay or a resume outlined below. I want to take every opportunity I can to market myself and demonstrate my interest in Columbia, but am worried an essay might be inappropriate here.

1) Essay format
- What I did?
- What I learned?
- How will those experiences help me at Columbia?
- How activity wil help in future career?

2) Resume Format
- Activity
- # of hours
- role and responsibilities

There is a 400 word limit, which makes me think it should be more substantial than just a resume.

Thank you for the help.
