I'd probably say no. If you do bad on a science course and retake it for GPA, you can say its b/c you wanted to make sure you had a strong science base for your higher classes. You are just taking it to be greedy it seems, I dont see a good justication for retaking such a class.
I think that it would be better for you to take another History or Humanity. If your overall GPA is that low, retaking wont help your GPA that much depending on your school's academic forgiveness policy.
Like every board member has ever told me. You will have so much redundant science when you get in that you should not worry about retaking any class that you dont feel will directly affect your success in Med school.
This is long winded... no, take Theatre instead... Admissions boards seem to really like it.
