I was reading up on Goro's advice for reinvention and was just wondering if I should retake a D I had in biochem? I only ask because while it isn't exactly a prereq (I took it for my minor in chemistry), I still feel like it weighs heavily on my application. I could understand why I wouldn't want to retake a D in a non-science related course, just wondering if I should for this one. For reference, I got C's in organic, a B in my second semester of biochem, and a B and a C in gen chem (not my best subject).
