I graduated from a T20 school in 2024 as a computational biology major, but I don't feel like I really learned anything from my biology and chemistry classes. I ended up with a 3.64 cGPA and around a 3.38 sGPA; I had mostly B's in my bio and chem classes and ended up with 2 C minuses in math classes because I couldn't GAF towards the end of my senior year. Bad, I know. Would it be beneficial if I retook the classes I didn't do very well in at a CC? I think it would be good to review/relearn stuff from my past classes for the MCAT, but it's been hard for me to find a straight answer as to whether retake grades from CC would replace what I originally got while at a university.
