Let’s talk briefly about the purpose behind this essay.
You’re not trying to give them a view of your writing style. It’s not about why you chose your major.
What you’re trying to do, in approximately 650 words, is “give them a reason to say yes.” You’re trying to separate the real you from your statistics-- from the other 400 kids whose statistics are exactly like yours. You want to leave the reader thinking “Now, THAT’S a kid we want on this campus!”
You’ve narrowed it down to 2 essays. Why not write a rough draft of each, and see which one you like better?
