Yep, i applied 2 years ago, and the lady said she will give me an interview if i could score 18 across the board, but i only had less than a week to reschedule to take my Dats... and by that time i hadn't studied, for a retake. I wrote a letter telling them it wasn't sufficent time, and could they reconsider. They wrote a letter back saying, sorry please apply back next cycle. So yea, Detroit Mercy is funny about scores. Some people i hear they let slide, but if you recieved that packet that they send to everyone who is considering going to the school, it says under DAT: To get an interview must score 18 in each section.
Go figure...
