Your PAT is amazing though I'll trade you my QR score for it 😉. Your grades are a bit on the low side; the DAT is fairly decent but if you really want to get bio up by all means do it. I retook it to get BIO up and surprisingly got a 7 point boost in gen chem as well. Your scores are incredibly similar to my first one. It's a matter of pride. My GPA isn't much better than you either; I'm not faring super well this app cycle but it's not over yet so I won't give up (or maybe I already haveee.. nah.. maybe... idk... let me cry on my own xD). I think GPA should be your main priority over retaking the DAT but if you think a retake is necessary I won't dissuade you for it. I couldn't be at peace with myself until I retook the DAT.
