If I was in your shoes right now, I would not even think about a re-take until I call up ALL the schools and explain to them your DAT numbers. Make a yes/no spread sheet, how many schools told you to retake how many told you to keep it.... If the retake number is higher, then retake.
But honestly, I think your fine man, I don't think theyr going to ask you to retake. RC is overrated
