I just graduated with a bs in biology. I would like to apply to D.O. schools. I had a 3.47 cumulative GPA and a 3.14 science GPA. I also had a semester of research and about 200 hours of hospital volunteering. Should I raise my science GPA before applying? I have three C+'s on my transcript. If I retake these three classes, I could raise it to a 3.4.
