College Essay HELP!!!?
Ok so I really need some advice on what to write about for my essay. I’m using the common app f.y.i. So anyways my first idea is to write about an experience that affected me and blah blah blah, so I was going to write about my school carnival which I co-chaired (it’s a pretty big deal lol, and apparently a lot of colleges know what it is), but I feel like that could be too generic, so I was going to think of something more original. For example at Vanderbilt they said the best essay they had ever read was about what a guy dressed up as every year for Halloween. So this was kind of lengthy and I hope understands this.
and if you had any other suggestions for essay topics it would be welcomed! (:

Write about the school carnival. Other students will be writing about their parents’ divorce or their grandma dying of cancer or their volunteer work, but most schools don’t have carnivals, so your essay will be different. It doesn’t really matter what you write about. What the schools are interested in is how well you express yourself in writing — grammar, vocabulary, sentence construction, your voice as a writer, and whether you have something interesting to say and an interesting way of saying it.
