Definitely not enough data yet to make any conclusions, but it looks like so far most of us are taking it prior to or right after June 3rd.
I know it does up your chances to get in early. But I am sure we have all heard stories of those who waited. I know someone who took the DAT in August, applied in Sep and was accepted at Colorado and UoP.
So if you take the DAT prior to June 3rd and automatically have them sent to the schools, does it confuse them getting scores without an application filled out?
I took the DAT May 9th and had the scores sent to the schools.. for most schools it is not a problem and they will match up the application with the scores when they receive your application. I called schools to make sure they had both.
