While all these posts where creative and amusing, I doubt these were the answers you were looking for...
I think the best thing you can do is bring your personality out on paper. They already know the details of your experience and all your qualifications... but what they dont know is who you really are as a person.
Think about what makes you stand out from all the other applicants. If you cant think of anything, then get some help from your close friends and family. Maybe share a funny story or something that is close to your heart.
Just try to avoid talking about your stats and experience because they will probably skim through your essay and not learn ANYTHING about you. Get a good attention grabber and just speak from the heart.
Finally, I think you might want to try going to the library and checking out some books on sample college entrance essays. I checked one out and it really inspired me to use some of my own uniqueness and I am pretty happy with my final result. Sorry that I don't remember the name of the book, but you can do a search at your library. Good luck! 👍
