My BA is in Clinical Physiology, D's were not accepted, which I had one and with retaking the course moved it up to a C+. I have debated retaking classes, but I have heard that programs do not take the better grade,or average the classes which may not increase your GPA very much, so it's time/money wasted. Does already having a BA of Science help at all, or will the application committee still only look at my low GPA, and solely decide off the numbers, you think?
