I'm applying to dental schools for 2019 cycle. I am junior currently sitting at 3.51 gpa, up from a 2.9 freshmen year(23 hours left to graduate). I haven't taken the DAT and haven't done any serious studying yet. I'm taking 3 upper div bio classes this semester and I'm doing only slightly above avg on the tests 80-88 range for low and high. How bad would it be for me if I ended up with a 3.5 gpa this semester? What's the lowest aa DAT score I need to achieve? 21-22?
