It is informal. You don’t need to lead with your name or say their college name (remember that you will use this same essay for multiple colleges, and it is attached electronically to your app, so no need to put any special header on it). It isn’t really an explaining type of essay – and giving a few specific examples is best, instead of just telling them about your qualities. It is best to “show”, not tell. Here is just an off the cuff example of something I might have said in a similar essay (because I loved to camp in HS, so this is really true for me):
"The rain was dripping down my neck, and I couldn’t get the knot untied to pull down the tarp on the sixth day of our wilderness camping trip. It was the fourth day straight of rain, and I hadn’t had a shower in a week, but this wasn’t what I had in mind when I thought about that. Some other group members were holed up in the tents eating candy and complaining, but I was actually giddy – because even when it is raining and we are out of fresh food and I’m getting wet, these wilderness trips are my favorite thing in the world.
One reason I love them is because they really strip away the veneer of civilization. You find out who is really hardworking, can stay positive when there is adversity, and has your back when things are tough. Who cooks or goes for water in the rain, and who hides out from the chores. Who still has a sense of humor, and who gets surly. Who goes back after reaching our destination and helps someone with their heavier pack. When I went on my first trips, I didn’t really realize that if I slacked on a chore, someone else had to do it. But happened, and I learned from that how pulling my weight and then some helps the whole group, and feels really good.>
Another thing I like is . Once <blah, blah,="" blah="">, and I realized .</blah,>
See the difference between a straight description and something more “showing”? (No one should use this example, the plagiarism checkers will get you).
But I’m just trying to help show a little bit about how to approach it.
Don’t worry about when they read your app. Worry about putting together the best app you can, getting your pieces in on time, and getting the requests for those other components made as soon as possible. The college admissions office won’t read it until they get all the pieces, but you will get a fair reading whether you turn it in a few weeks ahead or right before the deadline.
