Most selective colleges require you to submit an essay or personal statement as part of your application.
It may sound like a chore, and it will certainly take a substantial amount of work. But it's also a unique opportunity that can make a difference at decision time. Admissions committees put the most weight on your high school grades and your test scores. However, selective colleges receive applications from many worthy students with similar scores and grades–too many to admit. So they use your essay (along with your letters of recommendation and extracurricular activities) to find out what sets you apart from the other talented candidates.
So what does set you apart?
You have a unique background, interests and personality. This is your chance to tell your story (or at least part of it). The best way to tell your story is to write a personal, thoughtful essay about something that has meaning for you. Be honest and genuine, and your unique qualities will shine through.
Admissions officers have to read an unbelievable number of essays, most of which are forgettable. Many students try to sound smart rather than sounding like themselves. Others write about a subject that they don't care about, but that they think will impress admissions officers.
You don't need to have started your own business or spent the summer hiking the Appalachian Trail. Colleges are simply looking for thoughtful, motivated students who will add something to the first-year class.
