Undergraduate / 'From a Catholic Indian' - How I Can Contribute to UPenn's Community [5]

I like your essay, it is well written; however, you might want to add how you will contribute to it. Your paper focuses more on what Penn will do for you, not what you will contribute back.

Undergraduate / The way I see myself: Stanford essay. To my roommate! [8]

focusing on a couple aspects are alright, but you want to choose strong points.
you should check out my essay also.

Undergraduate / Princeton Supplement - about a person who has influenced you. (Harvard sup too!) [3]

It is a good essay, but you did not answer the prompt exactly, you focus more on you, then how your friend has influenced you, and why he influenced you. But overall it's a good essay just do not know if it is answering the prompt.

Undergraduate / A HAPPY ESSAY =) (my unique common app essay) [16]

your cause is a good one, I wish someone did that every time I am stressed
