You can't touch it until June 4th, but can do plenty to prepare. Can you believe it's only 2 weeks from today?
PM me your email address and I'll email you the application so you can check it out. There are general instructions out there (text format), but I've been getting good feedback from the people I've sent the actual application to. It does help to see it. It's a big PDF of how it all looks and what the matching forms look like and stuff.
Besides that, good luck on the DAT, and hopefully you have letter writers lined up.
