Well I am doing the Common App so here is what is written for the essay:
Please indicate your topic by checking the appropriate button below.
Evaluate a significant experience, achievement, risk you have taken, or ethical dilemma you have faced and its impact on you.
Discuss some issue of personal, local, national, or international concern and its importance to you.
Indicate a person who has had a significant influence on you, and describe that influence.
Describe a character in fiction, a historical figure, or a creative work (as in art, music, science, etc.) that has had an influence on you, and explain that influence.
A range of academic interests, personal perspectives, and life experiences adds much to the educational mix. Given your personal background, describe an experience that illustrates what you would bring to the diversity in a college community, or an encounter that demonstrated the importance of diversity to you.
Topic of your choice.
When I went to visit colleges, most colleges said they want essays that are interesting, show multiple qualites about yourself and basically you have to show yourself off to the college. They also said that the common app just gives some ideas the admission office would also like to see essays that have there own unique topics!
I'm sure you get the point I am making. No need for me to expand any further.
