Zilch,
I would not recommend writing "crazy b.s." in your essays. For his "platoon commanders essay" which all of us were required to write, one kid in my platoon apparently wrote a "humorous" essay. Im not sure if they were actually serious or not, but according to him the staff was considering kicking him out because of this essay...character flaws or lack of seriousness...something along those lines. Sounds kind of outrageous but I wouldn't be taking any chances.
Oh, make sure you write your essays in accordance with rules set by the staff... i.e. 300 word essay but the only words that count are over three letters. I didnt use proper heading and had one of my essays torn in half and had to re-write it. Yea, it sucked loseing sleep having to do it all over again.
Youll also probably get some pretty crazy topics. One of mine was "Why I should not chew my fingernails at OCS."
