If i were you, i would try to get my G.P.A past that 3.0 mark..both of them if its possible. take as many classes as you can this semester while you can sign up right now, and get past that 3.0 mark..i would reapply with the stats you have , but prob to several schools( just because you dont have much to lose ). i would also apply to a master program. I DONT THINK u need to retake the DAT, your scores are legit. the only red flag is the QR, but a good amount of schools dont care about that score, so its a little fine. that is the only reason I would retake it if i were you, but it seems as if now you should focus on your gpa, not your DAT.
