Four years ago, as a first-semester freshman in college, I took General Chemistry I and got an A. This was the last science class that I took in college. Now, I have enrolled in a postbac program, with the eventual hope of entering an allopathic medical school. The General Chemistry I course here covers different subjects, not to mention content that I have grown rusty at over the past few years. Would it hurt my future medical school applications to retake General Chemistry I at my postbac program? I know that retaking a course is generally frowned upon, although in my case, it would not be for strengthening my GPA (in fact, it could only harm it), but rather for helping me learn. I have thought about auditing the General Chemistry I course, although as an auditor, I would not be able to audit/participate in the lab. I worry that this would put me at a significant disadvantage for General Chemistry II lab.
