So the thing is if I want to apply for an SMP like wayne state or loyola, I need to have some sort of test score. I am devoting the entire summer to relearn the basics of biology, and chemistry and I have taken biochem already, so I have spent a lot of time fixing gaps. Instead of retaking my C+ in gen chem, bio 1 & pchem, would it be better if I took upper level courses to demonstrate that I am capable of handling science courses. I obviously need to fix the C-'s but would taking Upper level courses help? People have told me that it is a better route than retaking the classes with C+'s. What do you think?
