The quicker you get out of the habit of taking something because you believe it will "look good" the better. Take the courses that interest you and take the courses that are required. In the end, it's your performance and not the subject matter (other than the required courses) that will "look good" as long as you perform well.So I am talking with my advisor about having some other classes added to our science roster. I have always wanted to study embryology. Is this a class that will look attractive as an elective on medical school app?
