In looking at the list of averages of the entering class of 2007, the average is about a 3.45-3.5, and DAT around AA19, so yes, I'd say a 3.5 would be competitive, and a 3.8 would be extremely competitive. Remember that these are averages, so an equal amount of people below that GPA as above that GPA get in (says the guy who got into 3 schools with a 3.01 sGPA 😉 ).
