I *just* submitted mine. I felt that between my personal statement and their 3500 character "talk about a bunch of your activities and experiences and tell us your goals and how you're a good fit for Pritzker," that there really wasn't much left that I felt I needed to add. So, after agonizing about it for a few days, I just gave up and submitted it blank. What will be, will be. After all, I may have bombed the June MCAT, in which case it really won't matter what I said in my Pritzker secondary! Way to be optimistic, I know. But those May 31st score release threads have been eating away at my confidence and sanity.
