<p>I feel 1600 is too long. Remember that admission officers will be reading thousands of essays, and such a lengthy essay can be a turn off, unless of course the essay is exceptional and successfully grips the attention of the reader at all times. Having said that, the reader could also assume that you are unable to articulate your thoughts in a concise way, which is one of the things evaluated in the application process. But anyways PM me the essay. I want to see what you have written :-)</p>
