Your high school transcript contains at least three years of grades, showing evidence of hard work in a variety of subjects. Keep in mind essays are a major separating factor in sorting the mediocre students from those who have gone (and most likely will continue to go) above and beyond. I can’t even tell you how many wonderful application essays I’ve read about students’ mothers, fathers, brothers, grandmothers, neighbors, and even the ice cream truck driver being the most influential person in their lives. After reading them, I want to call the students up and encourage their grandmothers to apply! Don’t get me wrong, I love the essay prompts for many colleges, but some essay questions don’t exactly push for creativity or thinking outside of the box.
When there are only a few spots left in the class, you want to be the one they choose. I don’t recommend a friend who is afraid to correct your mistakes, or a parent, if you can help it.
If your essay is forgettable, well, you might be too. A teacher or family friend would be a great choice.
Since you already know how it’s supposed to read, and you’re accustomed to reading it, it’s often easier for another person to catch your mistakes.
You should also try reading the essay aloud to yourself.
