You'll be okay. I have a 3.2 and 20aa, applied to 17 schools, 6 pre-dec interviews, 1 post-dec interview. I have 2 acceptances and others on wait list/continuing review. Don't retake the DAT. Focus on ECs, getting great letters, and writing an amazing personal statement. If financially and physically possible, take classes for GPA, but I decided not to. Also apply early and wide. Do those things and you should be OK. Good luck!!!
