Retaking is a waste of time. If you do well, they’re going to think, “Well of course you did well, it’s your second time through the course.”
If you do poorly, they’re going to think “Gee, you can’t even do well on the second chance.”
This is what we call high risk, low reward.
Take some more science classes (i.e. immunology, genetics, microbiology, biochemistry, anatomy, physiology) and prove that your chem grade was a fluke–or at least that you can do well in science fields that are closer to medicine.
