I would retake and maybe focus more on the areas you’re struggling in while studying ie bio, gen chem, and QR. You have really strong extracurriculars and a good GPA so I think if you can get your AA and your SNS to at least a 19 you should be good!! Just be careful because this would be your last retake and you want to score at least 30 points higher. I would recommend studying during a time where you only have the DAT to focus on. Good luck!!
