I really don't want to be pessimistic, but I think retaking the DAT might be a tad too late. I'm assuming you'd take a few weeks to a month to study? Your GPA looks decent, but if you don't get in this cycle it'll probably be because of the late application and DAT score. Good luck on everything, though.
you got the numbers. I would say to look at the spreadsheet and apply to places that do alot of post Dec interviews. If not, next cycle you will be competetive. Your DAT is right at the average for accepted students.
