Do any of those schools require Dean's Cert besides W&L? I'm not complete there either but I know they're waiting to receive it from my school. As far as the Cornell email it sounds like you're complete. What does the status checker say?
Wow that story made me more paranoid than I already was about waiving my access to LORs and Dean's Certs. As it is i've been allowing at least a few days between mailing each dean's certification to my undergrad. I was worried they'd send Cornell's to BU, BU's to W&L, and so on. I wonder if the school would hold such a mistake against the applicant.
