What's Interesting to Them?

I took what advice you guys said and wrote the two essays required of me. I feel as if they’re interesting. (Of course, I don’t like to feel confident in myself because that’s usually indicative that I do worse than I think) I’ve been working for hours to cut them down, but one is 100 words over (limit 500) and the other is 200 words over (limit 800). I had to stop at these numbers so I could sleep. I will work on them more tomorrow in addition to finalizing a couple fly in apps since they’re due soon. Could any of you help me in cutting them down and critiquing them?
Also, to be safe, should I also get started on the additional writing supplements for all QB partners I plan to apply to if I don’t get matched as a finalist? This is a lot of writing… that’s around 12 different supplements. Not a lot of time to do it either. I still have to complete fly-ins. I’ve just been trying to bulk up my QB app quick. Is there any benefit to submitting the app early or are they all reviewed at once?
