Like everyone else said, don't give up hope! I have yet to hear from Kent either, but I know many of my friends have so it freaks me out! I emailed the coordinator today in hopes of finding out where I stand. My GRE scores are not great at all and I definitely understand how you feel about retaking it. I took it twice and can't imagine that I could have possibly done better/put myself through that stress all over again. It seems like you have great experience working at an autism center, I think that will help your applications.
I'm glad to have a fellow Ohioan on here!
